What's Changed

Learn about what changed in this release for QFX Series switches.

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.

  • Changes when deactivating or deleting instances of the ephemeral configuration database (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—The following changes apply when you deactivate or delete ephemeral database instances in the static configuration database:
    • When you deactivate the entire edit system configuration-database ephemeral hierarchy level, the device deletes the files and corresponding configuration data for all user-defined ephemeral instances. In earlier releases, the files and configuration data are preserved; however, the configuration data is not merged with the static configuration database.

    • When you delete an ephemeral instance in the static configuration database, the instance's configuration files are also deleted. In earlier releases, the configuration files are preserved.

    • You can delete the files and corresponding configuration data for the default ephemeral database instance by configuring the delete-ephemeral-default statement in conjunction with the ignore-ephemeral-default statement at the edit system configuration-database ephemeral hierarchy level.

    [See Enable and Configure Instances of the Ephemeral Configuration Database..]

Routing Protocols

  • 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

  • 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).]
