What's Changed

Starting from Junos 21.4R1 platforms with the following Routing Engines which have Intel CPUs with microcode version 0x35 observe the error warning, "000: Firmware Bug: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0x3a (or later)" on the console. RE-S-X6-64G RE-S-X6-128G REMX2K-X8-64G RE-PTX-X8-64G RE-MX2008-X8-64G RE-MX2008-X8-128G

Change to the commit process—In prior Junos OS and Junos OS Evolved releases, if you use the commit prepare command and modify the configuration before activating the configuration using the commit activate command, the prepared commit cache becomes invalid due to the interim configuration change. As a result, you cannot perform a regular commit operation using the commit command. The CLI shows an error message: 'error: Commit activation is pending, either activate or clear commit prepare'. If you now try running the commit activate command, the CLI shows an error message: 'error: Prepared commit cache invalid, failed to activate'. You then must clear the prepared configuration using the clear system commit prepared command before performing a regular commit operation. From this Junos and Junos OS Evolved release, when you modify a device configuration after 'commit prepare' and then issue a 'commit', the OS detects that the prepared cache is invalid and automatically clears the prepared cache before proceeding with regular 'commit' operation.

In a firewall filter configured with a port-mirror-instance or port-mirror action, if l2-mirror action is also configured, then port-mirroring instance family should be any. In the absence of the l2-mirror action, port-mirroring instance family should be the firewall filter family.

Support added for interface-group match condition for MPLS firewall filter family.

EVPN system log messages for CCC interface up and down events—Devices will now log EVPN and EVPN-VPWS interface up and down event messages for interfaces configured with circuit cross-connect (CCC) encapsulation types. You can look for error messages with message types EVPN_INTF_CCC_DOWN and EVPN_INTF_CCC_UP in the device system log file (/var/log/syslog).

Update to IGMP snooping membership command options— The instance option is now visible when issuing the show igmp snooping membership ? command. Earlier, the instance option was available but not visible when ? was issued to view all possible completions for the show igmp snooping membership command.

MLD snooping proxy and l2-querier source-address (ACX7024, ACX7100-32C, EX4400-24MP, PTX10001-36MR, QFX5120-32C, and QFX5130-32CD)— The source-address configured for proxy and l2-querier under the mld-snooping hierarchy should be an IPv6 link-local address in the range of fe80::/64. The CLI help text has been updated to "Source IPv6 link local address to use for proxy/L2 querier". In earlier releases, the CLI help text read, "Source IP address to use for proxy/L2 querier."

The xmlns:junos attribute includes the complete software version string (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX and vSRX)—The xmlns:junos namespace string in XML RPC replies includes the complete software version release number, which is identical to the version emitted by the show version command. In earlier releases, the xmlns:junos string includes only partial software version information.
