I have a following connection: WS-C2960G-24TC-L[Gi0/24] <-> [1/8]Brocade_switch
..and today after few flaps between the two switches because of the cabling works, the ports in both switches came up: Gi0/24 -> Brocade connected trunk a-full a-1000 1000BaseLX SFP ..and according to "show interfaces Gi0/24 switchport", the I Gi0/24 seemed to be working fine. However, I could not see any MAC addresses on VLAN's allowed to this trunk port. Finally I did "shutdown" and "no shutdown" to the Gi0/24 port and all of the sudden, I saw MAC addresses on VLAN's. There were no differences in "show int status" or "show int Gi0/24" before and after the "shutdown" and "no shutdown". I don't manage the Brocade switch. SFP in Gi0/24 is made by Finisar. There is nothing interesting in the log of the Cisco switch. I'm just curious, what might happened and how did the "shutdown"/"no shutdown" improve the situation? Or is it impossible to analyse such problems(afterwards)? regards, martin _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
