STACK -VLAN

hi all,

i am facing an issue. I've got two cisco 4503 to be configured as VTP Server mode. All vlans are created on this switches. I've got a stack of 3 cisco 3750 IOS 12.2(25) SEE2. and this stack has two gig link one connected to each 4503 switch. when i say show vlan on this stack i can see all the vlans. But problem is that switch 3 is become a master and if i congifure one port on switch 1 lets say fast 1/0/1 to be member of vlan xyz, the port will never work for this vlan or any vlan from vtp domain. If a confgure port 1 from switch 3 i.e. fast 3/0/1 and make it member of xyz vlan, all seems to work fine.

strange.

help pls.

Hi Adil,

Could you please paste the config from the stack. It would help us to find the issue.

Hi Adil,

can you make sure that switch-1 is working when it is individual with the vlan configured? u can simply erase the configuration & make it as an standalone switch rather than a stack switch.
