we have a typical VTP v2 server-client structure.
Now we are going to replace the 6509 with a VSS but this replacement cannot be made at once so both 6509 and VSS must co-exist for a while in the network.
Now my question: what is the best practice to migrate the VTP Server from the Catalyst 65009 to the VTP Server on the VSS?
Thanks for reply
As per the your network topology we can connect the switches
Before that Pl check the new core switch settings
Config rev number (0) default value new switches (the value should not be the higher then existing switch)
VTP password ( if you have )
You can verify the following command
show vtp status
configure the new switch
VTP mode : server
VTP domain : your existing (domain check the old switch )
VTP password ( same form old sw )
Establish Trunk connnection to new switch
This will download existing L2 VLANS and VTP info.
Later stage you can remove old 6509 take the config and put it into new switch.
I do not see any radical problems here. It is allowed to have multiple VTP Server switches in a network.
After setting up the VSS while having it still disconnected from your network, make sure that the VTP domain name and the VTP password (if used) are set up properly on the VSS. Also make sure that the VTP revision number as displayed in the show vtp status is lower than the VTP revision number in your network. Ideally, the VTP revision number on the VSS shall be set to 0 which can be done by setting the VSS to the VTP Transparent mode and back to VTP Server.
You now may set the VSS to the VTP Server mode and connect it via a trunk to your 6509. After the link comes up, the VSS will download the current VTP database. At your convenience, you may then remove the 6509.
