What’s Changed in Release 21.3R2

Network Management and Monitoring

  • SNMP support for MIB—Operational command show snmp mib walk system now shows the latest software version and does not show the build date.

    [See show snmp mib.]

  • 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.

  • Support for disconnecting unresponsive NETCONF-over-SSH clients (ACX Series, PTX Series, and QFX Series)—You can enable devices to automatically disconnect unresponsive NETCONF-over-SSH clients by configuring the client-alive-interval and client-alive-count-max statements at the [edit system services netconf ssh] hierarchy level. The client-alive-interval statement specifies the timeout interval in seconds, after which, if no data has been received from the client, the device requests a response. The client-alive-count-max statement specifies the threshold of missed client-alive responses that triggers the device to disconnect the client, thereby terminating the NETCONF session.

    [See ssh (NETCONF).]
