Need to pass info on VLAN 2363

what information?

the switch is set on VTP version 1. Do I just need do do the following:

what is the VTP  server version? make sure you do offline before connecting to switch, 

1. configure terminal
2. vtp version 3

3. vtp domain XXXX

4. vtp client
5. end

Then connect to the network and see switchable to get all the information from servers.

Hello,

provided you have a VTP domain name configured, all you need to do is indeed only to use the command 'vtp version 3' .

Be aware that only version 3 is capable of synchronizing extended Vlans, so you need version 3 enabled on all switches in your VTP domain in order for Vlan 2363 to be propagated. Also, version 3 is only compatible with version 2, not 1. And last but not least, with version 3 you might want to create a primary server in order to allow you to add/delete/change Vlans.

Hello
Extended vlans are compatible in vtp ver 1 however the vtp mode of the switch needs to be in transparent which defeats the object of automatically updating your vtp domain for extended vlan ranges, Also vtp modes 1/2 are not compatible within the same vtp domain.

As for vtp3, you can have multiple vtp servers just like vtp 1/2 however only one switch can be a primary server per vtp domain and this switch will the one responsible for allowing changes to the vtp database

For a switch to become vtp primary server (vtpv3)

• Change vtp ver to 3 (this WILL NOT change or erase the current vtp DB)
• Hide the password and Promote switch to vtp primary

Switch< vtp v3 primary sever>
conf t
vtp domain xx
vtp ver 3
vtp password xxxx hidden
exit
vtp primary force

Switch< vtpv3 client - Making sure password /domain are the same)

• Choose switch to become vtp 3 client
• Change vtp ver to 3 ( this will initiate a synchronization of the switch vtp DB to that of the new vtp3 primary server <above)
• Hide the password

conf t
vtp domain xx
vtp ver 3
vtp password xxxx hidden
exit
