Hi, i have experience a very odd issue with 5500 stacks a few times now and I am wondering if anyone else has seen it before:
5500 stack randomly loses a leg of its SMLT back to the core or drops off the network completely. When I check the logs of the 8600's which it connects to I can SLPP messages saying it has seen a loop on a particular VLAN from the 5500 stack. What is wierd is that the VLANs it see's the loop on, on one occasion didnt even exist on the 5500 stack and on the other two occasions the VLAN did exist but didnt have any access ports assigned - only the MLT ports. Sounds buggy to me, we are running code 6.1.5 on the 5500's.
Thanks,
Craig
