What's Changed

Learn about what changed in this release for PTX Series routers.

General Routing

  • On PTX10004, PTX10008, and PTX10016 routers, after executing the request node offline command, you must wait at least 180 seconds to execute the request chassis cb offline command.

  • Enhanced DDoS statistics operational command (PTX Series)—We've enhanced the aggregate DDoS statistics output field to display the aggregate statistics for BFD and DHCP protocols. The enhanced DHCP statistics output displays the collective DHCPv4 and DHCPv6 statistics for DDoS. Earlier to this release, the aggregate DDoS statistics output displayed 0 for aggregate BFD and the aggregate DHCPv4v6.

    [See show ddos-protection protocols.]

  • Disable power redundancy alarms for JNP10K-PWR-DC2 PSM (PTX10008 and PTX10016)- The JNP10K-PWR-DC2 PSM supports power redundancy across two DIP switches. When all input feeds are not connected to power supplies, it triggers a chassis alarm such as PSM 5 Input B0 and B1 Failed. Starting in Junos OS Evolved Release 24.2R1, you can disable this chassis alarm by using the set chassis alarm psm psm number input input number ignore command.

    [See JNP10K-PWR-DC2 Power Supply.]

  • DDoS protection protocols statistics update (PTX Series)—Starting in Junos OS Evolved Release 23.2R2, the show ddos-protection protocols statistics displays the Max arrival rate and Arrival rate output values as expected. Earlier to this release, the Max arrival rate and Arrival rate output values were displayed larger than expected.

    [See show ddos-protection protocols parameters.]

EVPN

  • Updates to syslog EVPN_DUPLICATE_MAC messages—EVPN_DUPLICATE_MAC messages in the System log (syslog) now contain additional information to help identify the location of a duplicate MAC address in an EVPN network. These messages will include the following in addition to the duplicate MAC address:
    • The peer device, if the duplicate MAC address is from a remote VXLAN tunnel endpoint (VTEP).
    • The VLAN or virtual network identifier (VNI) value.
    • The source interface name for the corresponding local interface or multihoming Ethernet segment identifier (ESI).
    For example: Feb 27 22:55:13 DEVICE_VTEP1_RE rpd 39839: EVPN_DUPLICATE_MAC: MAC address move detected for 00:01:02:03:04:03 within instance=evpn-vxlan on VNI=100 from 10.255.1.4 to ge-0/0/1.0.

    For more on supported syslog messages, see System Log Explorer.

Infrastructure

  • Option to disable path MTU discovery—Path MTU discovery is enabled by default. To disable it for IPv4 traffic, you can configure the no-path-mtu-discovery statement at the edit system internet-options hierarchy level. To reenable it, use the path-mtu-discovery statement.

    [See Path MTU Discovery.]

Junos OS API and Scripting

  • <get-trace> RPC support removed (ACX Series, PTX Series, and QFX Series)—The show trace application app-name operational command and equivalent <get-trace> RPC both emit raw trace data. Because the <get-trace> RPC does not emit XML data, we've removed support for the <get-trace> RPC for XML clients.

System Management

  • Additional Upgrade fields for the show system applications detail command (ACX Series, PTX Series, and QFX Series)—The show system applications detail command and corresponding RPC include additional Upgrade output fields. The fields provide information about notifications and actions related to various upgrade activities.

    [See show system applications (Junos OS Evolved).]

VPNs

  • Increase in revert-delay timer range— The revert-delay timer range is increased to 600 seconds from 20 seconds.

    [See min-rate.]

  • Configure min-rate for IPMSI traffic explicitly— In a source-based MoFRR scenario, you can set a min-rate threshold for IPMSI traffic explicitly by configuring ipmsi-min-rate under set routing-instances protocols mvpn hot-root-standby min-rate. If not configured, the existing min-rate will be applicable to both IPMSI and SPMSI traffic.

    [See min-rate.]
