Sorry, I wrote by mistake, any way its blocking.
All switches had the revision of 0.
So why when I change the SW2 from transparent to client all the switches
getting updated.

How can a port be desg, blocking?
Its desg, fwd, or alt, blocking. ;)
I suspect you are having an issue tracking the config revision number in
use. In your lab based on the roles you describe sw1 (server) will always be
able to update the client (STP ROOT) unless the client has a later config
revision number.

Subject: Strange VTP issue with vtp transparent
Hi
I found that the VTP server only sends the VTP packets over its SPT
designated ports not through the root port.
I have 4 switches, a ring topology
SW1-(desg)----------(root)-SW2
|(root) | (desg)(blocking)
| |
|(desg) |(desg)
SW3-(desg)--------(root)---SW4
SW1 is VTP server
SW2 is VTP Transparent
SW3 is VTP Client , STP Root
SW4 is VTP Client
All are same VTP domain CISCO
When I create vlan 2 on SW1, it will not affect other switches. (SW2, SW3,
SW4 still have original vlan database)
When I change the SW2 to VTP client, VTP propagates.
So this means that SW1 is not sending its VTP packets through the SPT root
port.
Any comment will help.
Regards
