Catalyst Question

[skhirbash]

What command is used to display the mac addresses of all interfaces on a switch?

Thanks,

SK

[JBUIST]

show mac-address-table

[bjw]

Try

SHOW MODULE X

Where X is the module # you want to get MAC addresses of.

I.e., SHOW MODULE 2

I have to mention that this is a Cat3560 switch that I am trying to use this commnad on. There is no "module" option on these types of switches.

The show mac-address command doens't work. I am trying to list all the mac address of all the interfaces residing on the switch and not the mac addresses learned and added to the CAM.

Thanks,

sK

Oh, ok SK

Try

show int fa0/1 | include address

Hardware is Fast Ethernet, address is 001b.5417.fa83 (bia 001b.5417.fa83)

If you do this for the fa0/1 interface, then the fa0/24 interface you'll have a linear MAC address range. The same holds true for Gig ports.

The bummer is that IOS doesn't have many interface range capable commands like the CatOS module command I referenced earlier.

[skhirbash]

Yes, it is a real bummer that I will have to use the show command on each int individually..

Thanks,

sK

If you just do a "show interface " that lists all the interfaces with the mac address , yes it is a lot to look thru but you don't have to do each one indivudually.
