Configuring Port VLAN Parameters

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:

	Table 13. VLAN Trunking Mode Options
VLAN Mode	Applies the following format to packets
	entering this port:
Clear	No VLAN tag. This is the default setting.
IEEE-802.1Q	The IEEE 802.1Q Ethernet VLAN tagging scheme.
Multi-layer	A widely available proprietary VLAN tagging
	scheme, that is fully Cisco ISL compatible.
3Com	3Com’s VLAN tagging scheme.

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.
