3Com 4500 Switch User Manual


 
2-2
z VLAN 1 is the system default VLAN, which needs not to be created and cannot be removed, either.
z The VLAN you created in the way described above is a static VLAN. On the switch, there are
dynamic VLANs which are registered through GVRP. For details, refer to “GVRP” part of this
manual.
z When you use the vlan command to create VLANs, if the destination VLAN is an existing dynamic
VLAN, it will be transformed into a static VLAN and the switch will output the prompt information.

By default, the VLAN interface
is enabled. In this case, the
VLAN interface’s status is
determined by the status of the
ports in the VLAN, that is, if all
ports of the VLAN are down,
the VLAN interface is down
(disabled); if one or more ports
of the VLAN are up, the VLAN
interface is up (enabled).
If you disable the VLAN
interface, the VLAN interface
will always be down, regardless
of the status of the ports in the
VLAN.
