Changing the Pruning-Eligible List

Configuring VLAN Trunks

Configuring an Ethernet Interface as a Trunk Port

The pruning-eligible list applies only to trunk ports. Each trunk port has its own eligibility list. VTP pruning must be enabled for this procedure to take effect.

SUMMARY STEPS

1.configure terminal

2.interface interface-id

3.switchport trunk pruning vlan {add except none remove} vlan-list[,vlan [,vlan [,,,]]

4.end

5.show interfaces interface-idswitchport

6.copy running-config startup-config

DETAILED STEPS

	Command or Action	Purpose
Step 1	configure terminal	Enters the global configuration mode.
	Example:
	Switch# configure terminal
Step 2	interface interface-id	Selects the trunk port for which VLANs should be pruned, and enters
		interface configuration mode.
	Example:
	Switch(config)# interface
	gigabitethernet2/0/1

Step 3	switchport trunk pruning vlan {add except
	none remove} vlan-list [,vlan [,vlan [,,,]]

Configures the list of VLANs allowed to be pruned from the trunk.

For explanations about using the add, except, none, and remove keywords, see the command reference for this release.

Separate non-consecutive VLAN IDs with a comma and no spaces; use a hyphen to designate a range of IDs. Valid IDs are 2 to 1001. Extended-range VLANs (VLAN IDs 1006 to 4094) cannot be pruned.

VLANs that are pruning-ineligible receive flooded traffic.

The default list of VLANs allowed to be pruned contains VLANs 2 to 1001.

Note To return to the default pruning-eligible list of all VLANs, use the no switchport trunk pruning vlan interface configuration command.
