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

Binds this port to all VLANs known to the switch.

All

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

Binds this port to any VLAN it receives traffic from.

Received

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.

 

 

5.From the Automatic VLAN Creation pull-down menu, select Enable to automatically create a VLAN each time the port receives a frame from an unknown VLAN.

*Note: This feature does not create entries in 3Com Mapping Tables. Refer to “Creating 3Com Mapping Tables”, in Chapter 12, for more information on 3Com Mapping Tables.
