Command History
Usage Guidelines Session is bidirectional and a reliable connection is established between two endpoints. Sync-data and
negotiation messages are sent to the peer endpoint through a session. On a Catalyst 4500 series switch,
each ISSU-aware client has a maximum of one session at each endpoint.
When an ISSU-aware client establishes its session with the 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 rollback-timer status:
Switch#show issu sessions 2072
Client_ID = 2072, Entity_ID = 1 :
*** Session_ID = 26, Session_Name = dot1x :
Peer Peer Negotiate Negotiated Cap Msg Session
