Context config>eth-tunnel>path
Description This command associates a port with the path defined under the Ethernet tunnel. If the operator wants
to replace an existing member port or control tag, the whole path needs to be shutdown first. The
alternate path will be activated as a result keeping traffic interruption to a minimum. Then the whole
path must be deleted, the alternate path precedence modified to primary before re-creating the new
path.
The following port-level configuration needs to be the same across the two member ports of an
Ethernet tunnel:
• port>ethernet>access>{ingress|egress}>queue-group
• port>ethernet>egress-scheduler-policy
• port>access>egress>pool
• port>ethernet>dot1q-etype
• port>ethernet>qinq-etype
• port>ethernet>pbb-etype
• port>ethernet>mtu
The Ethernet tunnel will inherit the configuration from the first member port for these parameters.
Additional member port that is added must have the same configuration.
The operator is allowed to update these port parameters only if the port is the sole member of an
Ethernet tunnel. This means that in the example below, the operator needs to remove port 1/1/4 and
port 1/1/5 before being allowed to modify 1/1/1 for the above parameters.
