perm Clears permanent entries. A permanent entry does not age

out and remains in the database even after a reboot, reset, or

power cycle. You must specify a VLAN name or number

with this option.

static Clears static entries. A static entry does not age out, but is

removed from the database after a reboot, reset, or power

cycle. You must specify a VLAN name or number with this

option.

dynamic Clears dynamic entries. A dynamic entry is automatically

removed through aging or after a reboot, reset, or power

cycle. You are not required to specify a VLAN name or

number with this option.

port port-list Clears dynamic entries that match destination ports in the

port list. You are not required to specify a VLAN name or

number with this option.

vlan vlan-id VLAN name or number—required for removing permanent

and static entries. For dynamic entries, specifying a VLAN

removes entries that match only that VLAN. Otherwise,

dynamic entries that match all VLANs are removed.

tag tag-value VLAN tag value that identifies a virtual port. If you do not

specify a tag value, UNIVERGE WL Control System

deletes only entries that match untagged interfaces.

Specifying a tag value deletes entries that match only the

specified tagged interface.
