Mike, I got back to this one today. Here is what I have at this time Switch A Fibre port 50 tagged, VLAN 2 Switch B Fibre port 50 tagged, VLAN 2
I still am seeing the same issue. I tried tagging both port 49 and 50 but that caused total loss of communications, on the admin VLAN 1 between the two. untagged port 49 on each end and got my admin VLAN back across the network. So now I am still trying to figure out what is going on. The link to the 200/300 switches does not even match the screens I have on these SG200-50p I did find another Cisco document that explained that I just needed to tag the two ends of the the VLAN 2 fibre ports (port 50 on each switch) that is what I have done but still get no data across the fibre. If I look at the Spanning Tree data, I see under STP Interface settings Switch A 49 GE49 Enabled Disabled STP Designated 20000 128 Forwarding 32768-f0:29:29:f5:43:bd 128-97 0 1 50 GE50 Enabled Disabled STP Designated 20000 128 Forwarding 32768-f0:29:29:f5:43:bd 128-98 0 1 Switch B 49 GE49 Enabled Disabled STP Root 20000 128 Forwarding 32768-f0:29:29:f5:43:bd 128-97 0 1 50 GE50 Enabled Disabled STP Alternate 20000 128 Discarding 32768-f0:29:29:f5:43:bd 128-98 0 0 This one says discarding for port 50, so suspect that is the issue. One other question, all of the ports on the VLAN 2 are marked [Trunk] should the end user/device ports be marked as [Access] or [General] I am wondering if this is causing any issues. All of the ports on VLAN 1 are also marked as [trunk] but they talk to anything that gets connected to the switch.
