If the remote-id is configured through the CLI on a specified VLAN, it can have either a user defined value, or the system-name. If the user does not configure the value or marks “none” as the remote-id, the switch MAC address will be used as the remote-id. The value of the remote-id present in the packet will have the following format:vlan_port_<remoteId, where remoteId will be either the configured string, or the system name or the switch MAC address. The Enterprise number field will be populated with the Extreme Networks enterprise number, “1916”.
If so, it verifies if the specific VLAN has a remote-id configured. If a remote-id is present, it is added to the packet along with the VLAN and port, in the format mentioned above. If it is not configured, the default (switch MAC address) will be added as the remote id, along with the VLAN and port.
If it is not present, the agent will check for the interface-id. If one of these is present, it will verify if the value matches the local configuration. If it matches, after removing the remote-id and/or interface-id, the packet will be forwarded to the respective client. If the remote-id is present in the packet, and it does not match the configured value, the packet will be dropped. If none of them are present, the packet will be forwarded to the client, based on the IPv6 address of the VLAN.
