Virtual Channels
Virtual channel and IPX Routing
The following commands create an ATM virtual channel on an ATM port and associate the port
with an IPX interface. This allows IPX routing between two IPX interfaces. As with any IPX
interface, IPX routing using RIP (the default) will begin when you configure an IPX interface.
Setting the Operation Mode for a Virtual Channel
You can set certain operational modes on a VC, such as enabling forced-bridging. Enabling forced-
bridging forces the VC to encapsulate all ingress/egress traffic into a Layer-2 frame. As a result, all
traffic passing through the VC group is formatted as bridged traffic. This feature is advantageous
when inter-operability between different vendor equipment is a concern.
To enable forced-bridging on a VC, enter the following command in Configure mode:
The following is a description of the parameters used with this command:
port <port> This parameter identifies the ATM port as well as the virtual channel identifier
(VCI) and virtual path identifier (VPI). Specify this parameter in the format:
media.slot.port.vpi.vci
media Specifies the media type. This is at for ATM ports.
slot Specifies the slot number where the module is installed.
port Specifies the port on where you want to create a virtual channel.
vpi Specifies the Virtual Path Identifier. This number identifies a particular virtual
path.
vci Specifies the Virtual Channel Identifier. This number identifies a particular
virtual channel.
forced-bridged Enables all traffic to be encapsulated as Layer-2 bridged traffic. This
parameter can be used for inter-operability between the XP and other
vendor products.
