Transparent—VTP transparent switches do not participate in VTP. A VTP transparent switch does not advertise its VLAN configuration and does not synchronize its VLAN configuration based on received advertisements, but transparent switches do forward VTP advertisements that they receive out their trunk ports in VTP Version 2.
It is indeed possible to have a VTP Transparent switch placed between a VTP Server and a VTP Client switches. However, in order for this VTP Transparent switch to pass VTP messages, its VTP domain name must either be unconfigured (i.e. NULL) or it must precisely match the VTP domain name used on the VTP Server/Client switches. And of course, all switches must be interconnected with working trunk ports because VTP messages are not sent through access links, only over trunks.
I changed domain name on transparent switch to 'null' and then changed it to domain name of other switches and it is working now.
The problem was I didn't set trunk to no-negotiate so vtp domain name was going in the DTP packets and that was causing trunks to go down. I changed trunk to nonegotiate and bounced trunk ports. Changed domain name to match and then it is all working ok.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
