ISL - Trunking Issue on Brocade 4100s

[shaque26]

I have noticed with Brocade 4100s, 6.1.0c firmware. The ISLs won't trunk consistently. Some time it does, some time both the links will show up as the trunk master. Has any one seen this?

Make sure your ISLs are connected on "consecutive" ports, or the same port groups.

for example: 0,1, 2, 3
