Use the set vtp pruneeligible command to specify which VTP domain VLANs are pruning eligible.
set vtp pruneeligible vlan_range
vlan_range | Range of VLAN numbers. |
The default is VLANs 2 through 1000 are eligible for pruning.
Switch command.
Privileged.
VTP pruning causes information about each pruning-eligible VLAN to be removed from VTP updates if there are no stations belonging to that VLAN out a particular switch port. Use the set vtp command to enable VTP pruning.
By default, VLANs 2 through 1000 are pruning eligible. You do not need to use the set vtp pruneeligible command unless you have previously used the clear vtp pruneeligible command to make some VLANs pruning ineligible. If VLANs have been made pruning ineligible, use the set vtp pruneeligible command to make them pruning eligible again.
This example shows how to configure pruning eligibility for VLANs 120 and 150:
Console> (enable) set vtp pruneeligible 120,150 Vlans 120,150 eligible for pruning on this device. VTP domain nada modified. Console> (enable)
In this example, VLANs 200-500 were made pruning ineligible using the clear vtp pruneeligible command. This example shows how to make VLANs 220 through 320 pruning eligible again:
Console> (enable) set vtp pruneeligible 220-320 Vlans 2-199,220-320,501-1000 eligible for pruning on this device. VTP domain Company modified. Console> (enable)
show vtp domain

ARP aging time is the period of time that indicates when an ARP entry is removed from the ARP table. Set this value by entering the set arp agingtime command. The remaining lines of the display show the mappings of IP addresses (or IP aliases) to MAC addresses.
