Displaying IS-IS Syslog messages
When logging is enabled, the device generates Syslog messages and SNMP traps for the following
IS-IS events:
• Overload state (the device entering or leaving the overload state)
• Memory overrun (IS-IS is demanding more memory than is available)
You also can enable the device to generate Syslog messages and SNMP traps when an adjacency
with a neighbor comes up or goes down. To enable logging of adjacency changes, refer to “Logging
adjacency changes” on page 879.
To display Syslog entries, enter the following command at any level of the CLI.
The messages in this example indicate that the software has been reloaded (Warm start) and
adjacencies between the device and three ISs have come up.
Syntax: show logging
Table 136 lists the IS-IS Syslog messages.
Type The IS-IS type of the adjacency. The type can be one of the following:
• ISL1 – Level-1 IS
• ISL2 – Level-2 IS
• ES – ES
NOTE: The device forms a separate adjacency for each IS-IS type. Thus,
if the device has both types of IS-IS adjacencies with the
neighbor, the display contains a separate row of information for
each adjacency.
Pri The priority of this IS to be elected as the Designated IS in this broadcast
network.
StateChgeTime The amount of time that has passed since the adjacency last changed
state.
