Parameter
Description
VTP Snooping State
Select Enable to enable VTP snooping globally for the switch. The default value is Disable.

Note: Enabling or disabling VTP Snooping does not clear any learned VTP information.

Domain Name
Enter the name associated with the Cisco VTP Domain. The default is Null (not set). Changing this parameter automatically clears the learned VTP information (the remaining parameters in this table).

Note: The domain name is automatically learned from a Cisco VTP switch provided both the Domain Name is Null and the VTP Snooping State is enabled on the switch.

Configuration Revision Number
Displays the VTP snooping configuration revision number associated with the last successful VTP configuration update on the switch.

Note: VLANs are only be learned by VTP Snooping when a received VTP message has a Configuration Revision Number greater than this learned value.

Updater Identity
Displays the IP address of the Cisco switch that initiated the VTP configuration update.
Update Timestamp
Displays the date and time that the Cisco switch initiated the VTP configuration update. The format of the timestamp is "yy/mm/dd.hh:mm:ss", where yy/mm/dd represents the year, month, and day and hh:mm:ss represents the hours, minutes, and seconds.
