The characteristics of the switch in this example are as follows:
?– The switch is transparent in the VTP domain.
?– The VTP domain name is ICND.
NOTE The domain name and password are case sensitive. You cannot remove a domain
name after it is assigned; you can only reassign it.

?– Pruning is disabled.
?– The con?¬?guration revision is 0.
802.1Q Trunking Configuration
The 802.1Q protocol carries traf?¬?c for multiple VLANs over a single link on a multivendor
network.
802.1Q trunks impose several limitations on the trunking strategy for a network. You should
consider the following:
?– Ensure that the native VLAN for an 802.1Q trunk is the same on both ends of the trunk
link. If they are different, spanning-tree loops might result.
?– Native VLAN frames are untagged.
NOTE In the output from the show vtp status command, ???VTP Version??? identi?¬?es what
version of VTP the switch is capable of running, and ???VTP V2 Mode??? indicates whether
VTP Version 2 is being used. If ???VTP V2 Mode??? shows disabled, VTP Version 1 is being
used.
