Question

Does CPPM allow configuring MTU for the management and data interfaces?

 

 

Answer

Starting from Clearpass Version 6.4, we have an option to set the MTU for management and data interfaces on Clearpass Policy Manager.

This is ONLY allowed from Cli. Web UI configuration of the same is not available.


Configure MTU usage

Log into the Cli of the CPPM server as appadmin user to configure this:

 

[appadmin@CPPM]# configure mtu <mgmt|data> <mtu-value>

 



Example:
========

[appadmin@CPPM]# configure mtu mgmt 1499
