We have two Catalyst 4507 connected to two sites at the same city throught a black fiber. We use the Gigabit Ethernet ports on the Sup V-10GE to connect the fiber via Cisco CWDM.
It is the second time that the superviser enginge V-10GE is frozen; L1 and L2 are correct on the switch, the link is well connected. but the switch does not response to IP requests like ping and ssh (L3 does not work). We should reboot the switch to resolve the problem.
When the problem is present do you have console connection? how is the proc cpu? Have you check the STP when the issue is there? Is chaging the uplink port to antoher port regain connectivity to the switch? Wihtout much more info, there no way to tell whether you are running into a bug or not.
