Hello fellow colleagues,
I have a really interesting question right here, it happened to me yesterday morning and trying to find any explanation was a bit difficult for this matter, maybe some of you guys could help me, here it is:
I had to add three VLANs to a medium sized switched network which had a quite big number of vlans for the size the network was (63 vlans) and I added them in the VTP Server switch for it to propagate them throughout the network. The thing is that two switches in the network were completely out and they were not communicating with anybody and could only see the CDP neighbor table, no telnet, no ssh, no ping, it just wasn't answering.
Knowing the fact that the switches that get to the maximum number of vlans configured (64) turn themselves into VTP Transparent mode doesn't mean that the switch will not communicate with anybody in the network and it does not reset the revision number, so there had to be something else here that affected the switch. I know that my configuration was the starting point but I believe that there was something in the switch previously configured that caused the outage.
Thanks in advance for your kind support
What switch model you were using in your network? Also, can you post the
output of "show vtp status" from the switches in question?
