What’s Changed in Release 21.4R2


DSCP rewrite on EVPN VXLAN NNI ports (QFX5130 and QFX5700)-- QFX5130 and QFX5700 platforms support DSCP rewrite on EVPN VXLAN NNI ports with limitations.

[See Implementing CoS on VXLAN Interfaces (Junos OS Evolved).]


  • 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.]

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.
