First off, I can't believe that this isn't working after what seems like a lot of good information out there about setting this up. However perhaps I am just missing something stupid due to sitting and staring at my screen too long.
That said, I have a couple 3750 switches that I am trying to run VTP Version 3 on....one as primary and the other as "server" which implies secondary from my research.
Switch01 configuration -
Switch01#sh vtp stat
VTP Version capable : 1 to 3
VTP version running : 3
VTP Domain Name : domainname
VTP Pruning Mode : Disabled
VTP Traps Generation : Disabled
Device ID : 70ca.9ba2.4380
Feature VLAN:
--------------
VTP Operating Mode : Primary Server
Number of existing VLANs : 15
Number of existing extended VLANs : 0
Configuration Revision : 20
Primary ID : 70ca.9ba2.4380
Primary Description : Switch01
MD5 digest : 0xCB 0xC9 0xE3 0x9C 0x91 0x7C 0xB5 0x3D
0x59 0xB2 0x02 0x7D 0xD7 0x3F 0x52 0x67
Feature MST:
--------------
VTP Operating Mode : Transparent
Trunk port enabled on port Gi1/0/1 -
interface GigabitEthernet1/0/1
switchport trunk encapsulation dot1q
Switch01#sh int gi1/0/1
GigabitEthernet1/0/1 is up, line protocol is up (connected)
Port Status on switch01 -
Switch01#sh int gi1/0/1
GigabitEthernet1/0/1 is up, line protocol is up (connected)
VTP Counters on Switch01 -
VTP statistics:
Summary advertisements received : 0
Subset advertisements received : 0
Request advertisements received : 0
Summary advertisements transmitted : 0
Subset advertisements transmitted : 0
Request advertisements transmitted : 0
Number of config revision errors : 0
Number of config digest errors : 0
Number of V1 summary errors : 0
So at this point, I thought everything looked good other than the fact that the counters indicate that no VTP communications are taking place.
Switch02 Configuration -
VTP Configuration -
Switch02#sh vtp stat
VTP Version capable : 1 to 3
VTP version running : 3

Feature VLAN:

Additionally, running a show VTP devices yields a "No VTP3 devices found" on both devices. Despite ensuring that the domainname and password match.
I have a patch cable from Gi1/0/1 on switch one runnning to Gi1/0/1 which from what I read is acceptable on GigE.
Does anyone with a clearer head than mine see anything wrong here or know of something to try?
Thanks,
james
