How to discover my Isl information on my network?

Hi,

i need to get the isl's information (both sides = pwwn and peer pwwn).

Up until lately, i used the command "show interface" and then i could get my pwwn and the peer pwwn from the trunking information.

I noticed that when the trunking prt is down (from a failure or some other reason, i don't get the necessary information from the commad).

can someone help how to get the WWN info of all the isl's in my network, regardless the port state?

I thought to use "show topology -isl" but it doesn't print me the WWN's that i needs.

Thank!

•show interface

•show interface trunk
