As Adam says if the 6500 supervisor is running IOS then the same way.
If it is running CatOS
6500# set port disable 2/4
6500# set port enable 2/4
where 2/4 would be the 4th port on module 2 in the 6500 chassis.
If I want to see all the mac-address on a 6509 (not the port addresses but the computer addresses that are connected to the 6509 what is the command?
I tried sh port mac-address 4 but that gave me all the port mac-addresses and not the computers. Help..
For 6500 with CatOS you will need
6500# show cam dynamic
to display all mac addresses
6500# show cam dynamic 6/20
to display the mac address on module 6 on port 20
you can filter the Vlans as for Vlan 6 type
6500# show cam dynamic 6
