Static Virtual LANs (VLANs)
Port-Based Virtual LANs (Static VLANs)
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 the appendix on troubleshooting in the
Manage­
ment and Configuration Guide .
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.
Jumbo Packet Support
Jumbo packet support is enabled per-VLAN and applies to all ports belonging
to the VLAN. For more information, refer to the chapter titled “Port Traffic
Controls” in the
Management and Configuration Guide
for your switch.
