I have a HWIC-D-9ESW installed into a 2821 and it won't take any port security commands. I'm running advanced IP services (12.4(15)t12) on the router. How can I configure it, or is it not supported? Thanks in advance for the help.
What kind of security features you are trying to enable under the HWIC interfaces?
Here is the configuration guide for the HWIC cards.
Hope this helps.
