Displaying CLNS

You can display the following information related to the CLNS protocol:

CLNS information about interfaces
Information about router adjacencies
Information about ES and IS neighbors
Protocol-specific information for each routing process
Information about CLNS packets
Global CLNS configurations

You can set a statistics baseline for CLNS using the baseline clns command.

baseline clns

Use to set a statistics baseline for CLNS.
The router implements the baseline by reading and storing the statistics at the time the baseline is set and then subtracting this baseline whenever baseline-relative statistics are retrieved.
Use the optional interface-specifier parameter to specify an interface; otherwise the command sets a baseline for all interfaces.
You cannot set a baseline for groups of interfaces.
When baselining is requested, the time since the last baseline was set is displayed in days, hours, minutes, and seconds.
Use the optional delta keyword with the show clns traffic command to specify that baselined statistics are to be shown.
