Table 5-8. VLAN Binding Field Pull-Down Menu Options
Option Definition
Static Assigns VLAN membership manually, using the VLAN Switch
Ports page described in “Creating and Implementing VLANs”, in
Chapter 11.
Bind to All Binds this port to all VLANs known to the switch. This is an
appropriate mode for switch-to-switch connections.
Note: When a tagged IEEE 802.1Q packet arrives on a port
that is set to bind to all and the VLAN does not exist on
the switch, the packet is forwarded on to the VLAN
assigned to the port default VLAN for that port. To
prevent unintended forwarding of unknown VLAN
traffic to the port’s default VLAN, configure the port
default VLAN to Discard. The automatic VLAN creation
feature will not work if the port’s default VLAN is the
discard VLAN, because the switch does not learn for this
VLAN.
if you use 3Com Mapping Tables, this setting is ignored.
Bind to Received Binds this port to any VLAN it receives traffic from.
Note: If Automatic VLAN Creation is enabled, the port binds to
previously unknown VLANs and a VLAN entry is added
to the switch VLAN table. If Automatic VLAN Creation is
disabled, the port does not bind to any VLAN unknown
to the switch.
