How Mobile Port Traffic that Does Not Match any VLAN Rules is Classified
OmniSwitch
If default VLAN is enabled....
Device traffic that does not match any
VLAN rules is forwarded on the mobile
port’s configured default 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.
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).
