Ta b l e 85 show issu sessions Field Descriptions
Field Description
Client_ID The identification number used by ISSU for that client.
Entity_ID The identification number used by ISSU for each entity within this
c
lient.
Session_ID The identification number used by ISSU for this session.
Session_Name A character string describing the session.
Peer UniqueID An identification number used by ISSU for a particular endpoint,
suc
h as a Route Processor or line card (could be a value based on slot
number, for example).
The peer that has the smaller unique_ID becomes the Primary
(
initiating) side in the capability and message version negotiations.
Peer Sid Peer session ID.
Negotiate Role Negotiation role of the endpoint: either PRIMARY (in which case the
d
evice initiates the negotiation) or PASSIVE (in which case the
device responds to a negotiation initiated by the other device).
Negotiated Result The features (“capabilities”) of this client’s new software were found
t
o be either COMPATIBLE or INCOMPATIBLE with the intended
upgrade process.
(“Policy” means that an override of the negotiation result has been
a
llowed by the software. Likewise, “no policy” means that no such
override is present to be invoked).
Cap GroupID Capability group ID: the identification number used for a list of
d
istinct functionalities that the client application contains.
Msg GroupID Message group ID: the identification number used for a list of formats
em
ployed when conveying information between the active device and
the standby device.
Session Signature Session signature: a unique ID to identify a current session in a shared
ne
gotiation scenario.
Nego_Session_ID Negotiation session ID: the identification number used by ISSU for
th
is negotiation session.
Nego_Session_Name Negotiation session name: a character string describing this
ne
gotiation session.
Transport_Mtu Maximum packet size (in bytes) of the ISSU messages conveyed
bet
ween the two endpoints.
A value of 0 means there is no restriction on size; in this case,
f
ragmentation and reassembly then are handled in a manner
transparent to the ISSU infrastructure.
