Table 14. VLAN Binding Options
Option Definition
Static Assigns VLAN membership manually, using the
VLAN Switch Ports page described in “Creating and
Implementing VLANs”, in the Cajun P550/P220 Switch
Operation Guide.
Bind to
All Binds this port to all VLANs known to the switch.
This is an appropriate mode for switch-to-switch
connections. If you use 3Com Mapping Tables, this
setting is ignored.
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.
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.
