Description
Displays the VTP operating mode, which can be
server, client, or transparent.
Server—A device in VTP server mode is enabled for
VTP and sends advertisements. You can configure
VLANs on it. The device guarantees that it can
recover all the VLAN information in the current VTP
database from NVRAM after reboot. By default, every
device is a VTP server.
The device automatically changes from VTP
Note
server mode to VTP client mode if it detects
a failure while writing the configuration to
NVRAM and cannot return to server mode
until the NVRAM is functioning.
Client—A device in VTP client mode is enabled for
VTP, can send advertisements, but does not have
enough nonvolatile storage to store VLAN
configurations. You cannot configure VLANs on it.
When a VTP client starts up, it does not send VTP
advertisements until it receives advertisements to
initialize its VLAN database.
Transparent—A device in VTP transparent mode is
disabled for VTP, does not send or learn from
advertisements sent by other devices, and cannot
affect VLAN configurations on other devices in the
network. The device receives VTP advertisements
and forwards them on all trunk ports except the one
on which the advertisement was received.
Maximum number of VLANs supported locally.
Number of existing VLANs.
Current configuration revision number on this device.
A 16-byte checksum of the VTP configuration.
