Usage Guidelines Messages are sync-data (also known as checkpoint data) sent between two endpoints.
When an ISSU-aware client establishes its session with a peer, an ISSU negotiation takes place. The
ISSU infrastructure uses the registered information to negotiate the capabilities and the message version
to be used during the session.
Examples The following example shows how to display the message groups for Client_id 2082:
Switch#show issu message groups 2082
Client_ID = 2082, Entity_ID = 1 :
Message_Group = 1 :
Message_Type = 1, Version_Range = 1 ~ 2
Message_Type = 2, Version_Range = 1 ~ 2
Switch#
