Upgrade Considerations


Before upgrading please review the Upgrade Considerations and the Rolling Back Software pages. Several modifications have been made to the process for verifying configurations, which will impact existing configurations.

  • I95-43243/IN-460 Upgrade and Rollback: Upgrading or rolling back a system (conductor peer or router) with the interactive installer install128t, that is managed by a conductor may result in the system becoming unresponsive. It is highly recommended that upgrades be performed through the conductor UI. Manual upgrades and rollbacks may not be resilient to failures. See Rolling Back Software for more information on these operations.

  • I95-42452 Conductor Upgrade Time: Upgrades to version 5.4 and above can take up to 40 minutes due to the number of rpms being upgraded. Please plan accordingly.

  • I95-42624 Upgrade Installer: Before upgrading to, or installing version 5.4 and above, update the Installer to at least version 3.1.0. Failing to upgrade the installer may result in a rollback failure, should a rollback be necessary at any time. The Installer typically prompts you update when a new version is available. Select Update when prompted.

  • Plugin Upgrades: If you are running with plugins, updates are required for some plugins before upgrading the conductor to SSR version 5.4.0 or higher. Please review the Plugin Configuration Generation Changes for additional information.

  • I95-51007 Conductor only - cpuProperties-core value isolating cores: In SSR software versions 6.0.0 and greater, the cpuProperties-cores setting in /etc/128technology/local.init is erroneously isolating cores on conductor nodes when set. Because the conductor does not forward packets, there should be no traffic cores allocated to or isolated on the conductor for packet forwarding. This setting was previously ignored on the conductor, but while resolving an earlier issue with the installer and initializer that allocated CPU cores for traffic, that is no longer the case.

It is recommended that prior to upgrading the conductor that the user modify local.init to set this setting to 0. For example, a setting like this in /etc/128technology/local.init:

  "cpuProperties" : {
"cores" : 4

should be changed to:

  "cpuProperties" : {
"cores" : 0

Note that only the relevant section of local.init is shown for clarity. All other settings should be left the same. The change should be made on both nodes of an HA system. If a conductor is already running 6.0.0 or later it will be necessary to systemctl restart 128T on each node after making this change. If the modification is made prior to upgrade it is not necessary to restart 128T service as this will be performed during the upgrade. Making this change on versions earlier than 6.0.0 will not affect operation, and will not require a restart.

This issue will be corrected in an upcoming release.

Release 6.0.10-5

Release Date: May 12, 2023

Resolved Issues Requiring Configuration Changes

  • I95-48862 Load balance sessions across BGP RIB Entries with multiple paths: Resolved an issue when BGP was used to build a routing table, only the first next hop was used. All next hops are now used, and load balancing occurs over all routing protocol routes.

  • I95-49354 Display SSD smartctl info in show platform disk: We now display the following disk info, if supported by the disk, in show platform disk:
    • Lifetime used
    • Power On Hours
    • TBW (Terabyte Written)
    • TBW per year

  • I95-49824 SVR Transport Reuse In deployments where the number of SVR sessions between SSRs are limited due to carrier settings, the established BFD transport session is reused to carry SVR sessions. For details about using this feature, see SVR Transport Reuse.

  • I95-50072 Support for ConnectX-6 Lx PCIe device: Support has been added for this device.

  • I95-50510 New fields for IPFIX: The SSR IPFIX implementation was not sending the industry standard fields of flowStartMilliseconds and flowEndMilliseconds. In the new implementation, all IPFIX records include these fields. The start time is set to the start time of the flow, and the end time is always set to the time the last packet was received on the flow. For intermediate records, this indicates that the flow is still ongoing but provides the last activity timestamp. For the end records, this indicates when the last packet was received on the flow prior to the session terminating. For additional information, see IPFIX.

  • I95-50571 Add packet buffer tracking to help analyze buffer exhaustion: The following features have been added to help diagnose packet buffer pool depletions in certain environments:
  • Track packet buffer locations.
  • Enforce setting of packet location.
  • Add the ability to walk packet buffer pools, count the locations, and display.

Resolved Issues

  • The following CVE's have been identified and addressed in this release: CVE-2021-44531, CVE-2021-44532, CVE-2021-44533, CVE-2021-44906, CVE-2022-35256, CVE-2022-21824, CVE-2022-28733, CVE-2022-2964, CVE-2022-4139, CVE-2023-22809, CVE-2023-21830, CVE-2023-21843, CVE-2022-4254, CVE-2021-25220 CVE-2022-2795, CVE-2022-38023, CVE-2022-37434, CVE-2023-0286, CVE-2023-0767, CVE-2023-0286, I95-50535, CVE-2023-23918, CVE-2023-23920.

  • The following issues have been identified during penetration testing and addressed in this release: I95-48445, I95-48448.

  • I95-37833 Apply password policy more consistently: The password policy for SSR users has been updated, and now requires passwords to have a special character in addition to previous requirements.

Please refer to Password Policies for updated password requirements.

  • I95-42379 BGP over SVR global service policy: Security and Service Policy configuration options are provided for specifying the policy to be used for generated BGP-over-SVR services.

  • I95-48485 Broadcom NIC (NetXtreme) fails to initialize properly: Resolved an issue with initization errors during memzone creation.

  • I95-48518 Application Identification not recognizing Apps: Resolved an issue where the GUI was only pulling Application data from one node in an HA configuration. Application ID Summary display now aggregates data from both nodes.

  • I95-49340 Crash when the unexpected input of tenant-prefix with no source-address is committed: Validation has been added to restrict the tenant-prefix source-address to a minimum of one.

  • I95-49350 BFD echo generating latency overhead: BFD echo tests are now staggered to minimize application latency's contribution to overall peer path latency.

  • I95-49447 Conditional BGP advertisement is not respected: Resolved an issue that if a peer went down and came back up, the conditional advertisement was no longer respected.

  • I95-49456 Ensure password requirements are configured: Password requirements are verified as configured.

  • I95-49514 Linux interfaces bounced on startup: Resolved an issue where all Linux interfaces managed by 128T are bounced once on 128T startup.

  • I95-49564 Reduce volume of logs during pending lookups: The error logs during a pending lookup has been changed to a muted error log with a stat.

  • I95-49603 Process Manager crash: When a long running process was being cleaned up by the subprocess, the cleanup would fail causing a crash. Long running processes are now properly terminated, which allows the cleanup subprocess to complete correctly.

  • I95-49604 Alarm when a node is disconnected: An alarm is now raised when a node is disconnected from the internal synchronization database.

  • I95-49633 Validation not strict for static assignment within DHCP server configuration: Configuration for static addresses within DHCP server exists in multiple locations per design. Cross-validation has been added to prevent the same ip-address from being configured and assigned to multiple dhcp-clients.

  • I95-49675 Incorrect path in console help message for export config running: The help message now correctly identifies the export path: Exported files are stored in /etc/128technology/config-exports/ and are stored as GZIP compressed files.

  • I95-49754 Waypoint re-use causing duplicate reverse flows: Resolved a case where when the waypoint pool is nearly depleted, released waypoints were reused prematurely causing errors when installing reverse flows.

  • I95-49791 Add audit rules to track modification of grub config files: Added rules to log notifications in case of changes to grub configuration files.

  • I95-49912 Login banner not displayed on serial console: The login banner is now displayed on the serial console.

  • I95-49913 Some Login/Logout events not logged in Audit Logs: All login and logout events are now logged in the audit logs.

  • I95-49925 GRE tunnel health-check not migrating sessions when path is down: The GRE tunnel manager now removes all sessions before adding new ones rather than modifying the existing sessions.

  • I95-49969 Permission Denied error when attempting to self-generate a webserver certificate: Resolved an issue that prevented users with the admin role from creating a new self-signed web certificate via the PCLI command create certificate self-signed webserver.

  • I95-49974 Stuck flow not cleared when reverse metadata is incomplete: Resolved an issue where reverse metadata is coming through incomplete - without the source tenant. The source tenant has been added to the reverse metadata.

  • I95-50014 Hitting Buffer Overflow during configuration changes: Resolved an issue where a config change request may not make it to a managed router, and returns a buffer overflow error.

  • I95-50034 Issues with stuck sessions in load balancer: Resolved an issue with session modify, where gateway changes on the same egress interface can fail due to a missing ARP.

  • I95-50047 Conductor config unable to pass local validation on one of the routers: Resolved an issue where a router missing the reachability-profile configuration may pass validation on conductor.

  • I95-50050 VRRP High Availability gets stuck in Active/Active: The DPDK version has been updated to resolve this issue.

  • I95-50247 Duplicate peer path alarms: Resolved an issue where both BFD and the path MTU feature were generating alarms for the same peer path being down. The criteria for which peerPath state changes can trigger peer path events has been tightened.

  • I95-50260 show idp events does not honor the router or node arguments: Resolved an issue where show idp events did not honor the router and node arguments and always executed against the local node. The command is now executed correctly, using the specified arguments.

  • I95-50262 Routers disconnected from their conductor may have incorrect log rotation settings: Resolved an issue where a managed router was not able to pull down the configuration from the Conductor - which includes the log rotation config. The default salt log rotation configuration has been improved, preventing the log from growing too large before the connection to the Conductor can be established.

  • I95-50269 Router clone operation fails: Implemented checks to prevent cloning obsolete elements and internal lists/containers on legacy versions of the SSR software.

  • I95-50286 Rebooting a node of an HA pair from Linux breaks routing: Resolved an issue where a delay in the shutdown process caused a node to take over a VRRP interface, creating routing issues.

  • I95-50331 System fails to synchronize keys on startup: The SSR now dynamically updates rsync IP host address from the non forwarding HA sync interfaces, and will fall back to the global.init host IPs if they don't exist.

  • I95-50363 MOS Metrics not refreshing: Resolved an issue where the SLA and MOS values were not being updated in the stats (or PeerPathTable) when a BFD session was brought down. The SLA and MOS stats are now set to 0 when the BFD session is brought down.

  • I95-50376 Failure to make config changes after rollback: Resolved an issue where commits would not take effect after rolling back an HA router, because of older/newer version conflicts.

  • I95-50445, I95-49377 i40e and ice devices enter malicious descriptor detection state, preventing forwarding of traffic: Resolved an issue where fragmented packet chains larger than 8 buffers were discarded causing a malicious descriptor event.
    • The below dpdk.log snippet provides an example of the event:
[DPDK| -- ] ERROR (00007f03ec18e700) i40e_dev_alarm_handler(): ICR0: malicious programming detected
[DPDK| -- ] WARN (00007f03ec18e700) i40e_handle_mdd_event(): Malicious Driver Detection event 0x02 on TX queue 6 PF number 0x01 VF number 0x00 device 0000:08:00.1
[DPDK| -- ] WARN (00007f03ec18e700) i40e_handle_mdd_event(): TX driver issue detected on PF
  • Added hooks for the NIC driver to trigger an unrecoverable event and invoke the Highway lockup detector mechanism.

  • I95-50534 Race condition between NetworkInterfaceManager and FastLane: Resolved a race condition caused by adding and deleting the same network interface in a very short window of time, potentially causing a system crash.

  • I95-50543 systemd unable to start 128T after upgrade: This issue has been resolved by ensuring that the netfilter kernel is installed.

  • I95-50554 No dynamic synchronization of repos to the routers: Resolved an issue where it was necessary to restart 128T on the Conductor in order for the Conductor to recognize newly added repositories and sync them down to the assets. Authenticated repos are now automatically synchronized when repos are added to the conductor.

  • I95-50699 Upgrade process to 6.0.8 failure: Mist-managed systems with low available memory could fail to upgrade. An updated dependency and fix for these Mist-managed systems has been published via the cloud and will be absorbed the next time a customer attempts an upgrade.

  • I95-50710 Configuration cannot be applied to router when its time is ahead of the conductor: Implemented time detection for configurations using a future time that is corrected upon commit. This resulted in an mtime older than what is in the datastore, and the configurations were rejected.

  • I95-50736 SSH key change not propogated to secondary conductor: Resolved an issue where an SSH key change to /etc/128technology/ssh/pdc_ssh_key was not automatically detected and resynced between peer node and conductor nodes.

  • I95-50754 Race condition between ICMP ping request and a reverse flow: Resolved a crash due to a race condition when service ping icmp-request is matched against a partially installed flow.

  • I95-50778 Event History filter not working: Resolved an issue where searching on the Event History page didn't show matching results when the search string is only found in the Details column.

  • I95-50787 Rebooting the OS from the conductor throws error code 400: Resolved an issue in the GUI with the reboot button on the Router page. When trying to reboot a router, the button would fail and display Error: EOF.

  • I95-50823 Support for time-offset DHCP option: int-32 encoded-type has been added to provide support for the time-offset DHCP option.

  • I95-50834 NodeMonitor crash on 128T startup when hardware interface is missing: Resolved a NodeMonitor crash when the interface configuration is not present.

  • I95-50967 SSR is not allowing other DHCP relay traffic to pass through: When the SSR acts as a DHCP Relay, it will no longer drop packets received from other relay agents on the network. Instead the packets will be routed appropriately as per the configured policies.

  • I95-50977 Installer fails to download software when the Conductor software proxy is enabled: Resolved an issue where when the Conductor software proxy is being used, DNF transactions to the conductor repo go through the proxy, despite the repo pointing to a local tunnel to the conductor. These transactions now go through the proper tunnel.

  • I95-50979 Routers remain in connected state: Resolved an issue where assets will perform a new highstate unnecessarily if a commit occurs while a highstate is already in progress, causing assets to take a long time to get to the running state.

  • I95-51006 Nodes stuck in connected state after upgrade: On an HA conductor, if the user is performing an upgrade on the first conductor node and that user makes a config commit during the upgrade, then the configuration's modified time will become out of sync between the two conductor nodes. When the conductor first node is finished upgrading the result is a loop where the configuration keeps getting committed by each node back and forth until a new commit is made. This issue has been resolved by allowing the peer conductor node to accept the config despite the perceived version disparity. Please note performing a commit mid-upgrade is not supported.

  • I95-51007 Conductor is incorrectly honoring core pinning: The cpuProperties cores setting in /etc/128technology/local.init was erroneously isolating cores on conductor nodes when set, even though this setting is intended for a router. This would cause a reduction in available processing cores for normal conductor operations. This setting will now be ignored on the conductor.

  • I95-51021 Package to Image conversion fails on FIPS enabled SSR: Conversion of package-based to image-based is now supported for systems with FIPS 140-2 mode enabled.

  • I95-51044 Hide forwarding-core-mode on conductor: Disabled the forwarding-core-mode setting on conductor nodes, since this setting does not apply to a conductor.


  • I95-51087 SSR fails to download firmware after upgrading the conductor: An issue has been identified where the first time a conductor is upgraded and conductor-only is selected in the software-update settings. The proxy service on the conductor does not work correctly, and downloads attempted by the router will fail. This issue will be resolved in the next release.

    Workaround: Make a simple configuration change and commit the change. Any configuration change is sufficient to start the internal proxy service. Once this commit has been made this will no longer be an issue.

Release 6.0.9-3

Release Date: April 3, 2023

Resolved Issues

  • I95-49594 Highway Crash: In a system where any of the following are configured:
    • application-identification is enabled,
    • a service is defined with domain-name child services, or
    • a service address is configured as a domain and there are established flows for any of these services, a link flap triggering a flow invalidation (changes to FIB) will induce a crash in the highway process of the SSR. This issue exists in versions 5.6.3 through 5.6.6, and is resolved in 5.6.7.
  • I95-50543 SSR may not start after upgrade: A race condition during startup may cause some services to start out of order, causing the SSR to not start. A reboot is required to start the system normally.

Release 6.0.8-20

Release Date: March 7, 2023

Resolved Issues Requiring Configuration Changes

  • I95-47947 Increase max CoreDump size to 4GB: The maximum size of coredumps now defaults to 4G. This value can be configured in environment config by modifying the maxCoredumpSize field of the new crashReporting object. Any manual modifications to coredump.conf will be overwritten whenever the service is started.

Upgrading to this release version will cause coredump.conf to be re-written with 4G limits for coredumps even if coredump.conf had been updated manually for a higher value!

  • I95-48571 IDP Topology User Experience Improvements: The SSR will include the auto-generated IDP mode when enabled as a part of show idp application status. Additionally, enabling hub mode will not result in engine bring-up errors.

Resolved Issues

  • The following CVE's have been identified and addressed in this release: I95-48464, I95-48859, I95-48907, I95-49039, I95-49079, I95-49445, I95-49745, I95-49746, I95-49747, I95-49748.

  • I95-34384 Rotated datastores with different permissions: Resolved an issue where some rotated datastore files had different permissions.

  • I95-46336 Peer connection not established after AWS upgrade: Resolved an issue where an AWS C5 instance size can fail to initialize when more than one accelerated network interface is configured.

  • I95-47797 Packet duplication does not interoperate well with outbound-only adjacencies: When utilizing the packet-duplication feature (service-policy -> session-resiliency = packet-duplication), any peer adjacencies marked as outbound-only are no longer used. Packets are only duplicated along bidirectional paths.

  • I95-47992 HTTP service not working in WAN Assurance: Resolved an issue where HTTP traffic is dropped when using a combination of application-identification, adaptive-encryption, and spoke-to-hub-to-spoke topology (outbound-only peer-connectivity).

  • I95-48054 STEP not working in Core Network: Resolved an issue where processing STEP route updates can cause modification of unrelated FIB entries, potentially interrupting existing sessions.

  • I95-48061 DHCP server not starting after upgrade: Resolved an issue where existing DHCP servers were not coming back up after upgrading from pre-6.0.X to post-6.0.X SSR software.

  • I95-48107 EoSVR sessions not stable: Resolved an issue with loss of connectivity to STEP EoSVR peer. The STEP route is now held in place and available when STEP connectivity is restored.

  • I95-48163 Only services with load-balanced paths are shown in show services: Resolved an issue where services without load-balanced paths were missing from show services output.

  • I95-48232 Ability to ping lost after failover: We now prevent unnecessary FIB changes (which may lead to a short traffic interruption) when new routes are added to the RIB that are more specific than some configured service IP prefixes.

  • I95-48324 Application Identification not parsing domain names: The App-ID parsing mode has been updated to correctly parse domain names.

  • I95-48352 Application ID is not identifying MS-Teams correctly: Resolved an issue where sessions with IP addresses as their domain names were not classified correctly. Sessions with IP addresses as their domain name are now verified against the IP tree, and not the domain name database.

  • I95-48396 show-rib limited to 512 entries: The show rib count maximum has been increased.

  • I95-48447 JWTs signing does not meet stringent security standards: Changed how JWTs are signed to increase security posture.

  • I95-48580 Application summary classification fails for hub-to-spoke sessions: The spoke now learns application names for sessions when receiving packets from a hub with application identification disabled.

  • I95-48581 Missing entry timestamp for show app-id cache: Additional timing information has been added to show app-id cache to help identify the oldest entry.

  • I95-48582 show bfd command ignoring parameters: The query parameters are now passed to the REST endpoint to be used byt the show bfd command.

  • I95-48590 ACK RTT Improvements: Resolved an issue where the stats were not resetting properly, and added supporting sampling to ACK RTT tracking.

  • I95-48641 Recreating BFD flow when an outbound-only session is reset: Flow creation is now deferred until a reverse packet arrives from the peer, similar to the initial creation case.

  • I95-48684 SSR not answering ARP requests: Increased internal-application traffic-engineering rates for ARP traffic which was being dropped in a multiple packet-processing core environment incorrectly due to an over aggressive traffic engineering profile.

  • I95-48689 Top Sessions not displaying source address: Restored the Source column in the Top Sessions table.

  • I95-48723 HA metrics sync not running after systems reconnect: Historical metrics and events are synced between HA nodes after extended downtime.

  • I95-48869 Validation for idp-policy incorrectly permits mixing modes across access-policies (e.g., strict and alert): The default IDP policy is now handled as IDP off in all cases.

  • I95-48872 show sessions by-id doesn't correctly display tcp state or retransmission counts: show sessions by-id now correctly display tcp state and retransmissions when udp-transform is enabled for a session.

  • I95-48897 Adaptive encryption breaks after flow move: Resolved an issue where the session breaks during failover when adaptive encryption is enabled.

  • I95-48904 Stuck pinhole session after flow invalidation: Resolved an issue with a stuck session that was setup from hub to HA spoke after a routing change.

  • I95-48927 Audit log disc failure mode: Added a Failure Notification parameter and failure mode to inform users that the auditd.conf log disc is nearing capacity, or has reached capacity, and that action is required.

  • I95-48942 Routing policy filter condition reference type not validated: Added a check to verify that when a routing policy condition references a filter, the condition type and filter type match.

  • I95-48950 Application identification modify packet is dropped: Packets with inline-modify that traverse the BFD pinhole are now handled correctly.

  • I95-48988 High CPU for packet processing core: Resolved an issue where the CPU can spike to 100% after a failover from internode/interrouter path to local breakout when failover is enabled for local breakout.

  • I95-49106 Degradation in performance during file rotation: This issue has been resolved.

  • I95-49118 HA LTE Interfaces go down and impact BGPoSVR and Conductor: The handling of FIB updates due to interface state changes has been optimized to avoid possible traffic loss for unaffected FIB entries.

  • I95-49134 DHCP server does not work when device IDs on HA interface do not match: Resolved an issue where a DHCP server interface may instead forward DHCP requests through the service-area and out to the WAN.

  • I95-49166 OSPF is not configurable using the GUI: This issue has been resolved.

  • I95-49225 Packets containing only path-metrics metadata are dropped: Resolved an issue where FPM calculations caused these packets to be dropped when flows were affected due to routing changes.

  • I95-49242 When HMAC is disabled, the automatic MSS adjustment calculation for enforced-mss = automatic may be wrong: The Automatic MSS adjustment calculation has been corrected (expanded).

  • I95-49341 BGP next hop exception being thrown: Resolved an issue where a duplicate BGP next hop resulted in an exception.

  • I95-49451 Secondary conductor failed to synchronize after upgrade: This issue was resolved by re-ordering the start up process for the 128T service.

  • I95-49454 Error while creating a new Radius user from the GUI: The create user API now rejects requests with invalid input parameters.

  • I95-49655 Cutting and pasting the output of show flat does not work for OSPF: Resolved the issue that prevented editing the OSPF list.

  • I95-49722 Event filter does not work on HA router nodes: Resolved issues with filtering by node, and an incorrect value was displayed for the node column in the GUI.

  • I95-49756 RDP sessions failure over peer path: Resolved an issue that caused RDP traffic to fail when adaptive encryption and AppId are both enabled.

  • I95-49778 Conductor GUI not showing data metrics for routers running: Resolved an issue where API keys were not properly synced down to the managed routers which caused certain router data to not show up on the GUI.

  • I95-50058 Performance regression in Running Config APIs: Resolved a constant cache miss for a specific set of the running config APIs.

  • WAN-1598 IDP Policies not set on the SSR: This issue has been resolved.
