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.
