How do you find the mac address for the Standby Supervisor

sho int mgmt0 works for the active but how do I get it for the standby on a Gen1 c9509 running 3.3.(1c) ?

Re: How do you find the mac address for the Standby Supervisor

I checked and was unable to come up with a display on the MDS that shows the standby's MAC. I did a system switchover and confirmed that each sup has it's own MAC.

You could look at the CAM table on the ethernet switch that the standby sup is attached to. If it's a Cisco switch 'show mac-addr table' I think is the command. Tou may have to unplug and re-plug the cable to populate the CAM table.

Hope this helps,

Mike

Can you do a "sh int mgt" while "attached" to the standby? (I don't have access to one while on the train!)

I figured it out.

sho module x (where x is the slot number of the standby sup.) Here's the output:

The Standby Supervisor

switchname1# sho module 6

Mod Ports Module-Type Model Status

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

6 0 Supervisor/Fabric-1 DS-X9530-F1-K9 ha-standby

Mod Sw Hw World-Wide-Name(s) (WWN)

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

6 3.3(1c) 4.0 --

Mod MAC-Address(es) Serial-Num

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

6 00-0e-38-c5-bc-80 to 00-0e-38-c5-bc-84 JAB00000000

The Active Supervisor

switchname1# sho module 5

Mod Ports Module-Type Model Status

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

5 0 Supervisor/Fabric-1 DS-X9530-SF1-K9 active

Mod Sw Hw World-Wide-Name(s) (WWN)

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

5 3.3(1c) 4.0 --

Mod MAC-Address(es) Serial-Num

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

5 00-0e-38-c5-bf-64 to 00-0e-38-c5-bf-68 JAB00000001

The output is much nice on my ssh session.

Nice...it does appear that the where it shows the MAC address range for the module, that the starting address is used for the MGMT 0 interface.

Thanks for the info,

Mike
