What’s Changed in Release 21.3R2

General Routing

  • Log messages are removed (MX Series)—When PTP Aggregate Ethernet primary is configured, and PTP Aggregate Ethernet secondary is not configured, the log message "Profiles are being modified" is removed.

  • No support for PKI operational mode commands on the Junos Limited version (MX Series, PTX Series, and SRX Series devices)—We do not support request , show , and clear PKI-related operational commands on the limited encryption Junos image ("Junos Limited"). If you try to execute PKI operational commands on a limited encryption Junos image, then an appropriate error message is displayed. The pkid process does not run on Junos Limited version image. Hence, the limited version does not support any PKI-related operation.

Layer 2 Ethernet Services

  • New output fields for subscriber management statistics (MX Series)—If you enable the enhanced subscriber management, the non-DHCPv4 bootstrap protocol (BOOTP) requests might not get processed even if you configure the DHCP relay or server with the overrides bootp-support statement at the edit forwarding-options dhcp-relay hierarchy level. To monitor the DHCP transmit and receive packet counters, we've introduced the following output fields for show system subscriber-management statistics dhcp extensive operational command. - BOOTP boot request packets received - BOOTP boot reply packets received - BOOTP boot request packets transmitted - BOOTP boot reply packets transmitted

    [See show system subscriber-management statistics.]

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").
