A link aggregator control which produces for a system in which the aggregator is located data units identifying the system and a partner identity for a partner system, and in response to a change from an old system identity to a new system identity produces data units identifying the new system identity and distinctively identifying the old system identity in place of the partner identity. Where the system identity and partner identity are each in the form of a globally administered unicast media access control the old system identity is represented in the form of a locally administered multicast address in place of the partner identity.
