Cisco MGX 8230 Edge Concentrator Installation and Configuration

Release 1.1.31, Part Number 78-11215-03 Rev. B0, May 2001

Chapter 5 Configuring the MGX 8230 Shelf

MGX 8230 MGX to BPX Feeder

The preceding MCR and PCR formulae are predicated on a relatively small frame size of 100 octets, and

even smaller frame sizes can result in worst-case scenarios. For example:

% Util should be set to the same value as that used for the Frame Relay segments of the connection.

CiscoView Configuration of a Feeder

This section describes how to use the CiscoView application to create and optionally modify the

characteristics of the logical ports on the MGX 8230 uplink card. It provides another way of configuring

the MGX 8230. To configure equipment on an MGX 8230, you must use Release 2.x or higher of

CiscoView. No CiscoView screen representations appear in this appendix. For a description of

CiscoView usage, see the CiscoView documentation. The task descriptions begin from the point where

you have already specified all IP addresses and the top-level CiscoView window is on-screen. The task

descriptions tell you how to:

• Specify that the application of the MGX 8230 is a feeder to a BPX series switch.

• At the card level, optionally specify the number of connections available to a network controller.

• Activate and optionally modify the characteristics of a line on the broadband interface of the MGX

8230 PXM—only one line for an MGX feeder.

• Create 1–32 logical ports on the line. By default, each network controller can compete for all the

resources you assign to the port.

• Optionally specify the amount of resources each network controller has on a logical port rather than

allow the controllers to compete for resources. (Note that for this release PAR is the only network

controller using MGX 8230 resources.)

Selecting an MGX 8230

To reach the target MGX 8230:

Step 1 Click on the File option at the top of the CiscoView - Main window, then click on the Open Device

option.

Step 2 Enter the node name or IP address of the MGX 8230 in the Device Select window. When the graphical

representation of the MGX 8230 shows the cards’ faceplate features, you can begin configuration.

Step 3 You can configure features from either the front or back view of the MGX 8230. Optionally, select a side

of the MGX 8230 through the View option at the top of CiscoView - Main.

For a frame size of 64 octects the PCR formula becomes: PCR = AR * 2/512 cells per sec

For a frame size of 43 octects the PCR formula becomes: PCR = AR * 2/344 cells per sec
