Chapter 10: Interface mode configuration

You can configure a port on an Avaya Secure Router 2330/4134 as an access port, a trunk port, or a
hybrid port.
You can enable Layer 2 switching on all Ethernet and WAN interfaces. The Secure Router 2330/4134
supports all Layer 2 switching features on WAN interfaces that are configured with PPP or FR
encapsulation. This section describes the supported interface modes and how to configure each mode
on LAN and WAN interfaces.

Configuring trunking on Ethernet interfaces

Trunk links are required to pass VLAN information between devices. You can configure a trunk
port to be a member of all the VLANs that exist on the device. That port then carries traffic for
all the VLANs between the devices. To distinguish between the traffic flows, a trunk port must
mark the frames with special tags as they pass between the devices. You must enable trunking
on both sides of a link. If two devices are connected together, for example, you must configure
both device ports for trunking.

Enabling trunking on an Ethernet port

Use the procedure in this section to enable trunking between the devices.
