Port-Based Virtual LANs (VLANs) and GVRP
Port-Based Virtual LANs (Static VLANs)
IP interface for that VLAN is also activated. Likewise, when a VLAN is
deactivated because all of its ports are down, the corresponding IP interface
is also deactivated.
VLAN MAC Addresses
The switch has one unique MAC address for each of its VLAN interfaces. You
can send an 802.2 test packet to this MAC address to verify connectivity to the
switch. Likewise, you can assign an IP address to the VLAN interface, and
when you Ping that address, ARP will resolve the IP address to this MAC
address. The switch allows up to 30 VLAN MAC addresses (one per possible
VLAN).
Port Trunks
When assigning a port trunk to a VLAN, all ports in the trunk are automatically
assigned to the same VLAN. You cannot split trunk members across multiple
VLANs. Also, a port trunk is tagged, untagged, or excluded from a VLAN in the
same way as for individual, untrunked ports.
Port Monitoring
If you designate a port on the switch for network monitoring, this port will
appear in the Port VLAN Assignment screen and can be configured as a
member of any VLAN. For information on how broadcast, multicast, and
unicast packets are tagged inside and outside of the VLAN to which the
monitor port is assigned, see “VLAN-Related Problems” on page C-18.
VLAN Restrictions
■ A port must be a member of at least one VLAN. In the factory default
configuration, all ports are assigned to the default VLAN
(DEFAULT_VLAN; VID = 1).
■ A port can be assigned to several VLANs, but only one of those assign­
ments can be untagged. (The “Untagged” designation enables VLAN oper­
ation with non 802.1Q-compliant devices.)
■ An external router must be used to communicate between tagged VLANs
on the switch.
■ Before you can delete a VLAN, you must first re-assign all ports in the
VLAN to another VLAN.
