Thanks,

Re: Catalyst Question

Try

SHOW MODULE X

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

I.e., SHOW MODULE 2

Mod Slot Ports Module-Type Model Sub Status

--- ---- ----- ------------------------- ------------------- --- --------

2 2 48 10/100/1000BaseT Ethernet WS-X6148-GE-TX yes ok

Mod Module-Name Serial-Num

--- -------------------- -----------

2 XXXXXXXXXX

Mod MAC-Address(es) Hw Fw Sw

--- -------------------------------------- ------ ---------- -----------------

2 00-0e-d7-9f-9c-b8 to 00-0e-d7-9f-9c-e7 5.0 7.2(1) 8.5(8)

Mod Sub-Type Sub-Model Sub-Serial Sub-Hw Sub-Sw

--- ----------------------- ------------------- ----------- ------ ------

2 Inline Power Module WS-F6K-VPWR-GE SAD07XXXXX 1.0 1.1(1)

Re: Catalyst Question

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,

Re: Catalyst Question

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.

Re: Catalyst Question

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

Re: Catalyst Question

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.
