Cisco MGX 8230 Edge Concentrator Installation and Configuration
Release 1.1.31, Part Number 78-11215-03 Rev. B0, May 2001
Chapter 6 Card and Service Configuration
Circuit Emulation Service Module for T3 and E3
Configuring the Card, Lines, and Ports
This section describes how to configure parameters for the card, line, and port through the CLI. If you
use the CiscoView application, refer to CiscoView documentation. The command sequence is:
Step 1 addln <line number>
where line number is 1. You can modify line characteristics with cnfln.
Step 2 Optionally execute cnfln to modify line characteristics:
cnfln <line_num> <line_code> <line_len> <clk_src>
• line_num is 1
• line_code is a number to specify line coding: 1 for B3ZS (T3); and 2 for HDB3 (E3)
• line_len is a number that specifies the line length: 1 for up to 225 feet; 2 for more than 225 feet
• clk_src is a number that specifies the clock source: 1 for local clock sourced on the PXM1; 2 for
looped clock
Step 3 Use dspln or dsplns to check the line. For dspln, the valid line number is 1.
Step 4 Create a logical port with addport:
addport <port_num> <line_num>
• port_num is the logical port number and is always 1
• line_num is the number of the physical line and is always 1
Step 5 Configure resources at the port level as needed by executing cnfportrscprtn:
cnfportrscprtn <port_num> <controller_name>
• port_num is the logical port number and is always 1
• controller_name is the name of the network control application. Enter one of the following strings:
PAR, PNNI, or MPLS
Step 6 Optionally configure Y-cable redundancy if you have connected the lines of adjacent CESMs through a
Y-cable. The applicable commands are addred, dspred, and delred. These commands run on the PXM1
rather than the service module, so you must change to the PXM1 CLI to execute them:
addred <redPrimarySlotNum> <redSecondarySlotNum> <redType>
• redPrimarySlotNum is the slot number of the primary card. The possible numbers are 1–6, 9–14,
17–22, and 25–30.
• redSecondarySlotNum is the slot number of the primary card. The possible numbers are 1–6, 9–14,
17–22, and 25–30.
• redType is the type of redundancy. Enter a 1 for 1:1 Y-cable redundancy.
Adding and Modifying Connections
Use either the Cisco WAN Manager application or the CLI to add or modify connections. If you use the
WAN Manager application, refer to the Cisco WAN Manager Operations Guide.
This section describes how to add a connection to a PXM1 in a stand-alone shelf according to the rules
for a standard connection or a management connection in the form of either a three-segment connection
or a DAX con. See “Rules for Adding Connections” earlier in this chapter. The preferred command is
