Usage Guidelines Session is bidirectional and a reliable connection is established between two endpoints. Sync-data and
negotiation messages are sen t to t he peer endpoint through a sessi on. On a Cat alyst 45 00 serie s 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:
