Configured Default
Port assigned to default VLAN 1
or another VLAN using the
vlan port default command.
VLAN 1
If restore default VLAN is enabled....
Why enable restore default VLAN?
Security. VLANs only contain mobile port
traffic that has recently matched rule criteria.
VPAs created from occasional network users
(e.g., laptop) are not unnecessarily retained.
If restore default VLAN is disabled....
Why disable restore default VLAN?
VPAs are retained even when port traffic is
idle for some time. When traffic resumes, it is
not necessary to relearn the same VPA again.
Appropriate for devices that only send occa-
sional traffic.
Configured Default
Port is assigned to other VLANs
when its traffic matches their criteria.
