I have the following scenario...
Having my CAT 4500 series CORE switch at one building and have the follwing switches at the other building
From the CORE switch the uplink comes to the CE500-Distribution, and all the uplinks of other switches in this building connect to the CE500-Distribution.
I have VTP configured on my CORE switch and on all the CAT 2960's, but not on CE500's as I belive they do not support VTP mode other than transparent mode.
I have the following Vlans on my CORE switch
Vlan 23,24,25,26 and 27.
I have created all these vlans on my CE500 switches too as they are VTP transparent.
Now coming to my problem, on my CE500 switches I assigned any of these vlans for the access ports I'm unable to get connected to my network, however on the CAT 2960's its working perfectly fine with all the Vlans
I have tried all type of port roles (I mean the smartport roles on the CE500), but nothing is working.... also this behaviour is the same for all the 3 CE500's...
(Note:- But when I disconnected all the uplinks of CAT 2960's from the CE500-Distribution, all the 3 CE500's works perfectly normal. I can get any of the vlans to my access port and get connected to my network.)
So what could be the problem? anyone can give me your inputs...
