Cisco Systems MGX 8230 manual Rules for Adding Three-Segment Connections

Chapter 6 Card and Service Configuration

Rules for Adding Connections

2.A stand-alone node supports DAX cons with one or both endpoints on the MGX 8230 PXM in addition to DAX cons between service modules.

3.Either endpoint can be the master.

4.The first endpoint to add is the slave. The generic syntax is: addcon <local parameters>

where local parameters are the port, DLCI or VPI and VCI, and mastership status. Slave is the default case, so you actually do not have to specify it. When you press Return, the system returns an identifier for this connection. The identifier includes the port and DLCI or VPI and VCI.

Use the returned identifier to specify the slave endpoint when you subsequently add the connection at the master end. The slave endpoint is specified as the remote parameters in item 5..

5.To complete the DAX con, add the master endpoint. The generic syntax is addcon <local parameters> <remote parameters>

where local parameters are the port, DLCI or VPI and VCI, and mastership status (master in this case). The remote parameters are the items in the connection identifier that the system returned when you added the slave endpoint.

6.If the endpoint is a MGX 8230 PXM port in a stand-alone node, specify the slot as 0. The addcon command is the only command in which you specify the slot number for the MGX 8230 PXM as 0.

Rules for Adding Three-Segment Connections

A three-segment connection consists of a local segment on each MGX 8230 at the edges of the network cloud and a middle segment across the network cloud. Figure 6-1illustrates a three-segment Frame Relay connection. The MGX 8230 requirements are:

1.For MGX 8230 feeders, the backbone must consist of MGX 8000 series or BPX 8600 series switches.

2.On a feeder, the local segment exists between a service module and the MGX 8230 PXM.

3.On a stand-alone node, the local segment can be between a service module and the uplink port on the MGX 8230 PXM.

4.For the local segment, add the connection at only the master endpoint. The generic syntax is: addcon <local parameters> <remote parameters>

where local parameters are the port, DLCI or VPI and VCI, and mastership status (master in this case). The remote parameters are the current nodename, slot, port, and VPI and VCI of the slave end. For the MGX 8230 PXM endpoints, specify the slot number as 0. The addcon command is the only command in which you specify the slot number for the MGX 8230 PXM as 0.
