The user needs to reserve VLANs using the system resource-profile g8032-control-sap-tags command. A maximum of up to 4 VLANs need to be reserved per line card. These VLANs are used to internally identify G.8032 CCM messages and R-APS messages. These VLANs cannot be used on any of the ports of the IMM, that is, SAPs cannot be configured with VLAN tag value matching any of the configured VLAN tags using this command.
