Before inserting a new switch in the network, the network administrator checks that the VTP
domain name is correct, the VTP mode is set to server, and revision is lower than the switches in
the network. The administrator then configures interfaces and trunks, erases existing VLANs, and
connects the switch to the network. Following that procedure, there is no connectivity in the
network. What is a possible cause of this problem?
A.
Because the configuration revision of the new switches is lower than the rest of the network, it
can change the VLAN database of the other switches.
B.
As a VTP server, the new switch deleted all VLANs of the network.
C.
Erasing VLANs increases the VTP configuration revision.
D.
Since the configuration revision of the network is higher than the new switch, the VLAN
database was automatically synchronized.
Explanation:
Reset the Configuration Revision Number
You can easily reset the configuration revision number by either of the two procedures provided in
this section.
Reset the Configuration Revision using Domain Name Complete these steps in order to reset the
configuration revision number with the change of the domain name:
1. Issue “show vtp domain” in order to see that the configuration is empty
2. Configure the VTP Domain name
3. Change the VTP Domain back
4. Change the VTP Domain to what it was in step 2
Reset the Configuration Revision using VTP Mode
Complete these steps in order to reset the configuration revision number with the change of the
domain name:
1. Issue “show vtp domain” in order to see that the configuration is empty
2. Configure the VTP Domain name
3. Change the VTP mode from server to transparent
4. Change the VTP mode from transparent to server or client.http://www.cisco.com/en/US/tech/tk389/tk689/technologies_tech_note09186a0080890613.shtml#t
