What’s Changed in Release 21.4R2
General Routing
-
OpenConfig container names for Point-to-Multipoint per interface ingress and egress sensors are modified for consistency from "signalling" to "signaling".
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 theignore-ephemeral-default
statement at the[edit system configuration-database ephemeral]
hierarchy level.
[See Enable and Configure Instances of the Ephemeral Configuration Database.]
-
User Interface and Configuration
-
Support for temperature sensor (PTX10001-36MR)—We support the temperature sensor statement at the edit chassis cb hierarchy level. You can use the temperature sensor statement to increase the fan speed and customize the temperature threshold. We recommend certain values for ZR and ZR-M modules to work which helps the temperature to remain within the thresholds.

VPNs
-
Changes to

outputs—The FwdNh output field displays the multicast tunnel (mt) interface in the case of Protocol Independent Multicast (PIM) tunnels.[See
