What’s Changed in Release 21.4R2

General Routing

  • JNP10K-PWR-DC2 power supplies installed in PTX10008 and PTX10016 routers display as online when the power supplies are switched off— JNP10K-PWR-DC2 power supplies installed in PTX10008 and PTX10016 routers in which Junos OS Release 21.4R1 or Junos OS Evolved Release 21.4R1 is installed display as online in the output of the command show chassis environment psm when the input power feeds are connected, but the power switch on the power supplies are switched off.

  • JNP10K-PWR-DC2 power supply does not support 5500 W or 2750 W if the power supply temperature increases above 60 degrees Celsius (PTX10008 and PTX10016)— If the power supply temperature increases above 60 degrees Celsius, the maximum power capacity of JNP10K-PWR-DC2 power supply installed in PTX10008 or PTX10016 routers reduces from 5500 W to 5000 W if four feeds are connected and from 2750 W to 2500 W if two feeds are connected. If there is no redundant power supply installed in the router, the router would shut down.

Multicast

  • Changes to show mvpn c-multicast and show mvpn instance outputs]-- The FwdNh output field displays the multicast tunnel (mt) interface in the case of Protocol Independent Multicast (PIM) tunnels.

    [See show mvpn c-multicast.]

Network Management and Monitoring

  • Change in behavior of SNMP MIB object ifAlias?SNMP MIB object ifAlias now shows the configured interface alias. In earlier releases, ifAlias used to show configured interface description.

User Interface and Configuration

  • A new field rollback pending is added to the output of show system commit that identifies whether commit confirmed is issued. It is removed once commit or commit check is issued or commit confirmed is rolled back after rollback timeout.

  • When you configure max-cli-sessions at the edit system hierarchy level, it restricts the maximum number of cli sessions that can coexist at any time. Once the max-cli-sessions number is reached, new CLI access is denied. The users who are configured to get the CLI upon login, are also denied new login.
