What’s Changed in Release 21.2R3

Class of Service

  • Junos OS Evolved now correctly displays the index for show class-of-service commands.

MPLS

  • When defining a constrained path LSP using more than one strict hop belonging to the egress node, the first strict hop must be set to match the IP address assigned to the egress node on the interface that receives the RSVP Path message. If the incoming RSVP Path message arrives on an interface with a different IP address the LSP is rejected.

Network Management and Monitoring

  • Changes to the NETCONF <edit-config> RPC response (ACX Series, PTX Series, and QFX Series)—When the <edit-config> operation returns an error, the NETCONF server does not emit a <load-error-count> element in the RPC response. In earlier releases, the <edit-config> RPC response includes the <load-error-count> element when the operation fails.

Routing Protocols

  • The RPD_OSPF_LDP_SYNC message not logged—On all Junos OS and Junos OS Evolved devices, when an LDP session goes down there is a loss of synchronization between LDP and OSPF. After the loss of synchronization, when an interface has been in the holddown state for more than three minutes, the system log message with a warning level is sent. This message appears in both the messages file and the trace file. However, the system log message does not get logged if you explicitly configure the hold-time for ldp-synchronization at the edit protocols ospf area area id interface interface name hierarchy level less than three minutes. The message is printed after three minutes.

  • To achieve consistency among resource paths, the resource path /mpls/signalling-protocols/segment-routing/aggregate-sid-counters/aggregate-sid-counterip-addr='address'/state/countersname='name'/out-pkts/ is changed to /mpls/signaling-protocols/segment-routing/aggregate-sid-counters/aggregate-sid-counterip-addr='address'/state/countersname='name'/. The leaf "out-pkts" is removed from the end of the path, and "signalling" is changed to "signaling" (with one "l").

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.
