Port Security

(config-if)#switchport port-security is, apparently, an unrecognised command.

And so is #show mac address-table.

Any ideas? It's a 2900 series switch running 12.0.

Cheers

I'm not sure if this matters, but what specific 2900-series are you using?

There are some pretty significant differences between them.

If it is running 12.0 then it is a 2900XL.

It is "port security" in a 2900XL I believe.

Hi I am sure these features are not available until 12.1, I'm sure someone will correct me if I 'm wrong. Your best bet is to get a 2950 as you will find the 2900 will be restricted on quite a few features.
Also check out the following link as a good guide to what features are supported on which platforms:

Catalyst 2900 XL and Catalyst 3500 XL Command Reference, 12.0(5)WC6 - Cisco IOS Commands [Cisco Catalyst 2900 Series LRE XL Switches] - Cisco Systems

theres a list of commands supported by the 2900 switch cant see any switchport port security commands.

show mac-address-table thats your mac address command

It is under "port security".

Huh? What hint?

Yes, it is just "port security" and not "switchport port security"

And "mac-address-table".

It's a shame that this switch doesn't use the commands as stated in the Lammle book - I might have a look for a 2950.

Thanks for your help.
