The SR OS platform provides a resilient out-of-band (OOB) management Ethernet redundancy mode for system management.
When the management Ethernet port is down on the active CPM, the OOB Ethernet redundancy feature allows the active CPM to use the management Ethernet port of the standby CPM, as shown in Figure 1 and Figure 2.
OOB management Ethernet port redundancy is enabled using the config>redundancy>mgmt-ethernet command.
