Cisco Systems EA6500 Manual De Usuario

When you enable or disable VTP pruning on a VTP server, VTP pruning for the entire management 
domain is enabled or disabled.

The pruning-eligibility configuration applies globally to all trunks on the switch. You cannot configure 
pruning-eligibility separately for each trunk.

When you configure VLANs as pruning eligible or pruning ineligible on a Catalyst 6500 series 
switch, pruning eligibility for those VLANs is affected on that switch only, not on all network 
devices in the VTP domain.

If there is insufficient DRAM available for use by VTP, the VTP mode changes to transparent.

Network devices in VTP transparent mode do not send VTP Join messages. On Catalyst 6500 series 
switches with trunk connections to network devices in VTP transparent mode, configure the VLANs that 
are used by the transparent-mode network devices or that need to be carried across trunks as pruning 
ineligible. For information about configuring prune eligibility, see the 

These sections describe how to configure VTP:

These sections describe configuring the VTP global parameters:

In Release 12.1(13)E and later releases, you can enter the VTP global parameters in either global 
configuration mode or in EXEC mode.

In earlier releases, you can enter the VTP global parameters only in EXEC mode.

To configure the VTP global parameters, perform this task:

Router(config)# vtp password password_string 

Sets a password, which can be from 8 to 64 characters long, 
for the VTP domain. 

Router(config)# no vtp password 

Clears the password.
