Understanding Mobile Port Properties
Assigning Ports to VLANs
page 6-14
OmniSwitch 6624/6648 Network Configuration Guide
April 2004
VLAN Management software on each switch tracks VPAs. When a mobile port link is disabled and then
enabled, all secondary VLAN assignments for that port are automatically dropped and the port’s original
configured default VLAN assignment is restored. Switch ports are disabled when a device is disconnected
from the port, a configuration change is made to disable the port, or switch power is turned off.
To view current VPA information for the switch, use the
show vlan port
command. Dynamic secondary
VLAN associations are identified with a value of
mobile
in the
type
field. For more information, see
“Verifying VLAN Port Associations and Mobile Port Properties” on page 6-19

If default VLAN is enabled....
Device traffic that does not match any
VLAN rules is forwarded on the mobile
port’s configured default VLAN until
the port is dynamically assigned to
another VLAN.
Configured Default
Why enable default VLAN?
Ensures that all mobile port device traffic is
carried on at least one VLAN.
If default VLAN is disabled....
Device traffic that does not match
any VLAN rules is discarded until
the port is dynamically assigned to
another VLAN.
Reduces unnecessary traffic flow on a port’s
configured default VLAN.
Restricts dynamic assignment to mobile port
traffic that matches one or more VLAN rules.
Device connected to a mobile port sends traffic. If the traffic matches
existing VLAN criteria, then the mobile port and its traffic are
dynamically assigned to that VLAN.
If device traffic does not match any VLAN rules, then the default
VLAN property determines if the traffic is forwarded on the port’s
configured default VLAN (VLAN 1 in this example).
Configured Default
VLAN 3
Why disable default VLAN?
