Logging Adjacency State Changes
You can configure the router to log messages that track when adjacencies change
state between up and down.
log-adjacency-changes
Configuring LSP Parameters
You can specify the following parameters for LSPs:
lsp-gen-interval
Example
host1(config-router)#ignore-lsp-errors
Use the no version to disable the function.
See ignore-lsp-errors
Use to generate log messages that track IS-IS adjacency state changes (up or
down).
The default is not to log adjacency state changes.
Recommended for monitoring large networks.
The system logs messages by using the router error message facility.
Specify the minimum severity (0–7) or verbosity (low, medium, high) of this log
category's messages.
You can also use the system log command to generate the desired log messages.
Example
host1(config-router)#log-adjacency-changes severity 3 verbosity low
Use the no version to disable the function.
See log-adjacency-changes
Maximum transmission unit (MTU)
Transmission rate
Generation rate
Maximum lifetime
Use to set the minimum interval rate that LSPs are generated on a per-LSP basis.
You can set an interval value in the range 0–120 seconds.
The default interval value is 5 seconds. When a link is changing state at a high
rate, the default value limits the signaling of the changing state to once every 5
