If you configure a remote ID sub-option in both system view and on a port, the remote ID sub-option configured on the port applies when the port receives a packet, and the global remote ID applies to other interfaces that have no remote ID sub-option configured.

In a port aggregation group, you can use this command to configure the primary and member ports respectively. When Option 82 is added, however, the remote ID is subject to the one configured on the primary port.

The remote ID configured on a port will not be synchronized in the case of port aggregation.
