Configuring VTP Pruning on a Catalyst 1900 Switch

To configure the switch for VTP pruning, use the following command:

1912(config)# vtp pruning

Configuring VTP on a Set/Clear CLI Switch

Before you can configure a router or internal route processor for interVLAN routing, you must enable VTP, assign a mode, and configure a domain.

1.You enable and configure VTP and VLANs on the switch in Privileged mode. To enable VTP and specify a VTP mode, use the set vtp mode {client server transparent} command, as follows:

5002> (enable) set vtp mode server VTP domain modified

2.If you set the mode to client or server, then you need to set the VTP domain name and password on the first switch. The VTP name can be up to 32 characters long. The password is a minimum of 8 characters with a maximum of 64. For our example, we set the mode to server. The following shows the available syntaxes for the set vtp domain option:

5002> (enable) set vtp domain ?

Usage: set vtp [domain <name>] [mode <mode>] [passwd <passwd>] [pruning <enabledisable>] [v2 <enabledisable>

(mode = clientservertransparent

Use passwd Ô0’ to clear vtp password) Usage: set vtp pruneeligible <vlans>

(vlans = 2..1000

An example of vlans is 2−10,1000)

You must configure a VTP domain name if you choose to configure the switch as a VTP client or server. To do so, use the set vtp domain name command, as follows:

5002> (enable) set vtp domain Coriolis VTP domain Coriolis modified

3. Set the password to “pass1” for the VTP domain with the following command:

5002> (Enable) set vtp passwd pass1

Configuring VTP on a 1900 Cisco IOS CLI Switch

The 1900 switch does not require you to set the VTP password, just the domain name. The following shows the options available for the vtp domain command:

1900EN(config)#vtp		domain ?
WORD Name of the		VTP management domain
1900EN(config)#vtp		domain Coriolis ?
client	VTP	client
pruning	VTP	pruning
server	VTP	server
transparent	VTP	transparent
trap	VTP	trap

Here is an example of setting the domain to “Coriolis” on the 1912EN:
