Web Agent Procedure

To configure VTP snooping using the Web Agent:

1. Select Configuration from the Modules & Ports folder on the Web Agent window. The Module Information window opens (see Figure 6-11).
2. Select the number in the Switch Ports column for the module you want to configure VTP. The Switch Ports window for that module opens (see Figure 6-13).
3. Select the port in the Name column on which you want to enable VTP Snooping throughout the switch. The Switch Port Configuration window opens for that port (see Figure 6-14).
4. Select either IEEE 802.1Q or Multi-layer from the Trunk Mode pull-down menu to match the setting of the trunk mode for the switch port at the other end of the link.
5. Select Enable from the VTP Snooping pull-down menu. This enables VTP snooping on the switch port.
6. Click APPLY to save your changes, or CANCEL to restore previous settings.
7. Select VTP Snooping from the L2 Switching > VLANs folder on the Web Agent window. The VTP Snooping Configuration window opens (see Figure 6-16).

8. See Table 6-4 and configure the VTP Snooping parameters.

   Table 6-4. VTP Snooping Parameters

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