show vtp
Table 2-55 show vtp status Field Descriptions
Field Description
VTP Version Displays the VTP version operating on the switch. By default, the switch implements Version 1
but can be set to Version 2.
Configuration Revision Current configuration revision number on this switch.
Maximum VLANs
Supported Locally
Maximum number of VLANs supported locally.
Number of Existing
VLANs
Number of existing VLANs.
VTP Operating Mode Displays the VTP operating mode, which can be server, client, or transparent.
Server: a switch in VTP server mode is enabled for VTP and sends advertisements. You can
configure VLANs on it. The switch guarantees that it can recover all the VLAN information in
the current VTP database from NVRAM after reboot. By default, every switch is a VTP server.
Note The switch automatically changes from VTP 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 switch 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 switch 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 switch receives VTP advertisements and forwards them on all trunk ports
except the one on which the advertisement was received.
VTP Domain Name Name that identifies the administrative domain for the switch.
VTP Pruning Mode Displays whether pruning is enabled or disabled. Enabling pruning on a VTP server enables
pruning for the entire management domain. Pruning restricts flooded traffic to those trunk links
that the traffic must use to access the appropriate network devices.
VTP V2 Mode Displays if VTP Version 2 mode is enabled. All VTP Version 2 switches operate in Version 1
mode by default. Each VTP switch automatically detects the capabilities of all the other VTP
devices. A network of VTP devices should be configured to Version 2 only if all VTP switches
in the network can operate in Version 2 mode.
VTP Traps Generation Displays whether VTP traps are sent to a network management station.
MD5 Digest A 16-byte checksum of the VTP configuration.
Configuration Last
Modified
Displays the date and time of the last configuration modification. Displays the IP address of the
switch that caused the configuration change to the database.
