Displaying IPv4 IS-IS information
Displaying the IS-IS SPF Log
The show isis spf-log command displays the ISIS Log, as shown in the following.
Syntax: show isis spf-log {detail | level-1 [detail] | level-2 [detail] }
This display shows the following information.
TABLE 49 IS-IS SPF log information
This field... Displays...
When When (in hours: minutes : seconds) a full SPF calculation occurred. The
last 20 occurrences are logged.
Duration The time required to complete this SPF run, Elapsed time is normal clock
time (not CPU time). Other options for this field are:
•
Running – the SPF is still running and the duration will be updated
after the SFP has run.
•
Pending – the event is pending and another SPF will be run once
the currently executing SPF has completed.
Nodes The number of routers and pseudonodes (LANs) that make up the
topology calculated in this SPF run.
Count The number of events that triggered this SPF run. When a topology
change has occurred, multiple link-state packets (LSPs) are received in a
short time. Since a router waits about 5 seconds before running a full
SPF run, it can include all new information. This count includes the
number of events (such as receiving new LSPs) that occurred while the
router was waiting the 5 second interval before running full SPF.
