Defining VLAN Port Assignments Configuring VLANs

Enabling/Disabling VLAN Mobile Tag Classification
Use the vlan mobile-tag command to enable or disable the classification of mobile port packets based on
802.1Q VLAN ID tag. For example, the following commands enable the mobile tag attribute for VLAN
1525 and disable it for VLAN 224:
-> vlan 1525 mobile-tag enable
-> vlan 224 mobile-tag disable
If a mobile port that is statically assigned to VLAN 10 receives an 802.1Q tagged packet with a VLAN ID
of 1525, the port and packet are dynamically assigned to VLAN 1525. In this case, the mobile port now
has a VLAN port association defined for VLAN 10 and for VLAN 1525. If a mobile port, however,
receives a tagged packet containing a VLAN ID tag of 224, the packet is discarded because the VLAN
mobile tag classification attribute is disabled on VLAN 224.
In essence, the VLAN mobile tag attribute provides a dynamic 802.1Q tagging capability. Mobile ports
can now receive and process 802.1Q tagged packets destined for a VLAN that has this attribute enabled.
This feature also allows the dynamic assignment of mobile ports to more than one VLAN at the same time,
as discussed in the above example.
VLAN mobile tagging differs from 802.1Q tagging as follows:
If 802.1Q tagging is required on a fixed (non-mobile) port, then the vlan 802.1q command is still used to
statically tag VLANs for the port. See Chapter 11, “Configuring 802.1Q,” for more information.
VLAN Mobile Tag 802.1Q Tag
Allows mobile ports to receive 802.1Q
tagged packets.
Not supported on mobile ports.
Enabled on the VLAN that will receive
tagged mobile port traffic.
Enabled on fixed ports; tags port traffic
for destination VLAN.
Triggers dynamic assignment of tagged
mobile port traffic to one or more
VLANs.
Statically assigns (tags) fixed ports to one
or more VLANs.
