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
