Hi all,
I have question here where Switch 1 is in VTP server mode
3550SMIA# sh vtp status
VTP Version : running VTP2
Configuration Revision : 26
Maximum VLANs supported locally : 1005
Number of existing VLANs : 10
VTP Operating Mode : Server
VTP Domain Name : manveer.com
VTP Pruning Mode : Enabled
VTP V2 Mode : Enabled
VTP Traps Generation : Enabled
MD5 digest : 0xEB 0xEA 0xDE 0x00 0x23 0x6E 0xEB 0x00
Configuration last modified by 192.168.10.1 at 6-17-12 21:08:59
Local updater ID is 192.168.10.1 on interface Vl10 (lowest numbered VLAN interface found)
I created vlan 50
then gave it name Test
*****************************************************************************************************************************
Switch 2
On client switch which has VTP mode set to client
2950B#sh vtp status
VTP Version : 2
Configuration Revision : 26
Maximum VLANs supported locally : 250
Number of existing VLANs : 10
VTP Operating Mode : Client
VTP Domain Name : manveer.com
VTP Pruning Mode : Enabled
VTP V2 Mode : Enabled
VTP Traps Generation : Disabled
MD5 digest : 0xEB 0xEA 0xDE 0x00 0x23 0x6E 0xEB 0x00
Configuration last modified by 192.168.10.1 at 6-17-12 21:08:59
I do not see vlan 50
2950B#sh vlan
VLAN Name Status Ports
---- -------------------------------- --------- -------------------------------
1 default active Fa0/2, Fa0/3, Fa0/4, Fa0/5
Fa0/6, Fa0/7, Fa0/8, Fa0/9
Fa0/11, Fa0/13, Fa0/14, Fa0/15
Fa0/16, Fa0/17, Fa0/18, Fa0/19
Fa0/20, Fa0/21, Fa0/22, Fa0/23
Fa0/24, Gi0/1, Gi0/2
10 VLAN0010 active
20 VLAN0020 active
30 VLAN0030 active
40 VLAN0040 active
However when on Switch 1 which is server and layer 3 switch i did
int vlan 50
now i went back to Switch 2
2950B#sh vlan
VLAN Name Status Ports
---- -------------------------------- --------- -------------------------------
1 default active Fa0/2, Fa0/3, Fa0/4, Fa0/5
Fa0/6, Fa0/7, Fa0/8, Fa0/9
Fa0/11, Fa0/13, Fa0/14, Fa0/15
Fa0/16, Fa0/17, Fa0/18, Fa0/19
Fa0/20, Fa0/21, Fa0/22, Fa0/23
Fa0/24, Gi0/1, Gi0/2
10 VLAN0010 active
20 VLAN0020 active
30 VLAN0030 active
40 VLAN0040 active
50 Test active
My question is why we need to config int vlan 50 command in order to replicate vlan 50 into to client switches?
Also second question is vtp config revision number is still same 26 on both client and server even after i created new vlan 50 why?
Thanks
Mahesh

You should not have to create a SVI to replicate a L2 vlan to the client, could be a bug but a 3550 is end of life so it wont be fixed if it is . Are sure the config revision number wasnt 25 before you started the config ?

Hi Glen,
Thanks for reply.
I created 1 more vlan on VTP server 3550 switch .
It was not SVI VLAN.
This time config rev number incremented on all switches from 26 to 28 and i can see the vlan name on all client switches.
So all seems to be good now.
Regards
MAhesh
