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 Chapter 12, 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 Configuration for Port
XX 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 3-8. describes the VLAN Trunking Mode options:
Known Mode Select to enable or disable known mode. The
default value is Disable.
3Com Mapping Table Select how incoming tagged frames from
3Com equipment are mapped to Lucent
VLANs. The default value is 3ComDefault.
Mirror Port Displays whether the mirror port is enabled
or disabled. This is a Fast Ethernet only
option.
