I have a K-12 customer with the follwing setup.
Juniper 4550 in the MDF
10G links to IDF's with a S2500-48P in the IDF's
We have PVST turned on
Each switch has a data vlan, voice vlan and a mgmt vlan(customer is using V1 for this..I know! bad practice.)
The problem we are seeing is the IDF switches become unavailable from a management stand point. Traffic still flows out of the switch but you cannot reach it to manage it. All of the bridge ID's were set at 32768. Lastnight I had a call with TAC and they changed one of the ones we couldnt communicate with to 36684 and that fixed it, but then another IDF became unavailable. I changed it and then another IDF became unreachable on the mgmt vlan...and so on. I really dont want to have to go back and change every single 2500. The other odd thing is, I am not seeing this at every campus. Only at 2 of the 5 we have deployed to this date. We are deploying 13 more campuses in the next week or so. Really would like to **bleep** this in the bud quickly before the problem spreads.
PVST is disabled on the Juniper switch for vlan 1 only
Thanks in advance for any solutions or suggestions!!
