RE: Not the whole domain - Re: Delete VLAN [7:37254]
Your quote from the book answers your own question. A switch in transparent mode does not partake in the VTP process. Switches in the same VTP domain that are either servers or clients do. So a change made on a server propagates throughout the VTP domain changing the information on the other servers and the clients. The prior responses to your question are correct. What might be confusing is the part that says you can't delete VLANs on a client. Clients don't save the VLAN information. They only learn it from servers. Change the server and you automatically change the clients.

But I really got confused. Pls read the following excerpt about Deleting VLAN from the book of Cisco LAN Switching written by Clark Hamilton : You can remove VLANs from the management domain using the clear vlan vlan_number command. For example, if you want to remove VLAN 5 from your VTP management domain, you can type the command clear vlan 5 on a Catalyst configured as a VTP server. You cannot delete VLANs from a VTP client Catalyst. If the Catalyst is configured in transparent mode, you can delete the VLAN. However, the VLAN is removed only from the one Catalyst and is not deleted throughout the management domain. All VLAN creations and deletions are only locally significant on a transparent Catalyst. So, according the above words, it just remove the portion of vlan 5 on that Catalyst which clear command was executed. Is it right? From Woody's answer to my last question : Vlan 5 will also be cleared on all switches that are configured as clients as well. Also, any port that is configured on those switches will also lose their vlan assignment to vlan 5. I raised another question: if Woody is right, the portion of vlan 5 on the Catalysts configured as clients will also be removed, then my question is: Will all clients or just clients configured from that server-Catalyst which clear command is executed be removed?

Re: Not the whole domain - Re: Delete VLAN [7:37254]
mlh, the thing is, VLAN 5 will be deleted from the following switches: - all server-mode switches on the VTP domain, regardless of which one the command was issued - all client-mode switches on the VTP domain VLAN 5 won't be deleted from the following switches: - all switches that are in transparent mode on the VTP domain - any other switch that is not in the VTP domain Persio - Original Message - From: mlh To: Sent: Tuesday, March 05, 2002 2:06 PM Subject: Not the whole domain - Re: Delete VLAN [7:37254] Hi,Dave, First, thank you for your answer.

RE: Not the whole domain - Re: Delete VLAN [7:37254]
let me try to explain a little better. Server - Has the ability to add and remove VLan's for a Domain. This will remove the vlan from all switches that are clients on the domain. Client - Can't add or delete a Vlan from the Domain. All information about Vlan's is received from the Server. Transparent - Can add and delete Vlan's but only on that switch. No other switches in the Domain will be affected.

Re: Not the whole domain - Re: Delete VLAN [7:37254]
What that blurb is saying is that if you remove a VLAN on a switch running transparent mode the VLAN will only be deleted on that switch. This is correct, transparent mode is basically turning VTP off. If you clear the VLAN from a server in the VTP domain then you will clear the VLAN on all switches within said domain. In Client mode you you can't do VLAN manipulation, the Server/s is/are King. Dave mlh wrote: Hi,Dave, First, thank you for your answer. But I really got confused.

RE: Not the whole domain - Re: Delete VLAN [7:37254]
I belive that the part about a VTP client not saving VLAN information is not correct. Yes, a client gets updates from the VTP server and Yes changes (add,delete,mods) can only be initaited on a server. But, I belive that the client does save the most current revision of the VTP domain config in memory. Also, If a VTP server reloads and some how loses (or has cleared) its VLAN info but retains the VTP domain configuration and its revision number somehow is lower than a clients revision, the server will accept config the VLAN conifguration from the client. Atleast that is what I think/remember. Oleg Oz...

RE: Not the whole domain - Re: Delete VLAN [7:37254]
One more thing I forgot to mention. If a Client is powered off and disconnected (physicaly) from the network and then powered on. The client will retain the last known VTP domain/VLAN configuration.
