Software Installation and Upgrade

  • Optimize reboot times by disabling default initialization and startup of certain Layer 2 applications (ACX7332)—Starting in Junos OS Evolved 23.4R1-S1, when rebooting the device, the Layer 2 (L2) applications l2ald, l2ald-agent, l2cpd, and l2cpd-agent are initialized and started only if any of the following configuration hierarchy levels contain any configuration statements:

    • [edit interface interface-name unit number family ethernet-switching]

    • [edit vlans]

    • [edit routing-instance instance-name instance-type virtual-switch]

    • [edit routing-instance instance-name instance-type mac-vrf]

    • [edit protocols l2-learning]

    Additionally, l2cpd, and l2cpd-agent are initialized and started if the [edit protocols lldp] hierarchy level contains any configuration statements.

    As a result of this change, if your configuration already contains these configuration statements and you then delete all of them, these L2 applications stop running.
