Port VLAN parameters determine how a particular port’s traffic is 
flooded to VLANs when tagged and untagged packets are received 
on the port. See the examples later in this section for 
recommendations on settings for particular trunk port connections.

Refer to “VLAN Operation”, in the Cajun P550/P220 Switch Operation 
Guide, for more information on creating VLANs.

Refer to “Viewing Switch Port Parameters”, earlier in this chapter, 
for information on accessing the Switch Port dialog box.

To configure port VLAN parameters:

1. From the Port VLAN pull-down menu in the Switch Port dialog 

box, select a

 VLAN as the VLAN assignment for this port. This 

causes all untagged frames arriving on this port to be assigned to 
the specified VLAN. The port will still assign incoming tagged 
packets to the VLAN indicated by the tag.

2. From the Trunk Mode pull-down menu, select the option 

(excluding Clear) to indicate that the port is a trunk and to 
select the appropriate VLAN trunking format if the port is 
connected to another switch.

Table 13. describes the VLAN Trunking Mode options:

3. From the Frame Tags pull-down menu, select whether you 

want to 

Ignore or Use received Frame VLAN tags. If you ignore 

VLAN tags on incoming frames, the frames are bound to the 
port’s default VLAN.

4. From the VLAN Binding pull-down menu, select a VLAN 

binding type for this port. 

No VLAN tag. This is the default setting.

The IEEE 802.1Q Ethernet VLAN tagging scheme.

A widely available proprietary VLAN tagging
