MDS 9506 WWN

Postby Guest » Tue Aug 31, 2010 6:26 pm


I have been told by EMC to find the WWN for the 9506 MDS switch. How would i find this? I thought WWN was port based. is there a WWN for the sup modules or  the Chassis?

Thanks in advance

There are wwn's that are on the switch's side of each port and is known as the FWWN. There is also a switch WWN that is an identifier for the switch. That can gotten with this command:

show wwn switch.

Is this a new command in the OS. I did not find this on the CLI or is this hidden?. I was told by EMC that the command for this is "Show switch summary" but this was wrong.

thanks in advance

No, this is a pretty old  command. Here is one from a lab:

lab9216# show wwn switch

Switch WWN is 20:00:00:0d:ec:27:00:c0

If you are having trouble, can you post your show ver and show wwn switch results?

I tried this command and sent it to EMC, they told me that this is not the correct WWN. this is the show version.
