Chapter6 Card and Service Configuration
Eight-Port Circuit Emulation Service Modules
Configuring Service on an Eight-Port CESM
This section describes the steps for setting up a CESM and adding connections. The maximum number
of connections is 248 on the MGX-CESM/B-8E1 and 192 on the MGX-CESM/B-T1. Use either the CLI
or the Cisco WAN Manager application to set up a CESM and add connections. The following list shows
the fundamental tasks and applicable CLI commands:
• Optionally configure redundancy at the card level (addred and possibly addlink on the PXM1)
• Optionally modify resource partitions at the card level (cnfcdrscprtn)
• Activate a physical line (addln) and optionally configure the line (cnfln)
• Create logical ports for structured data transport on a physical line (addport)
• Optionally modify resource partitions at the port level (cnfportrscprtn)
• Add connections by using addcon (or addchan if NSAP addressing is necessary)
For CESM-related commands, see the list of service module commands at the beginning of the Cisco
MGX 8000 Series Command Reference. Also, each command description in the command reference lists
related commands. For example, it shows display commands that relate to addition commands.
Configuring the Card, Lines, and Ports
This section describes how to configure parameters for the card, lines, and ports through the CLI. If you
use the CiscoView application, refer to the CiscoView documentation. On the CLI, the command
sequence is:
Step 1 addln <line number>
where line number is in the range 1–8. You can modify line characteristics with cnfln.
Step 2 Optionally execute cnfln to modify line characteristics from the defaults. (Use dspln or dsplns to
check). The syntax for cnfln is:
cnfln <line_num> <line_code> <line_len> <clk_src> [E1-signalling]
• line_num is a line number in the range 1–8
• line_code is a number that specifies the line coding: 2=B8ZS (T1); 3=HDB3 (E1); and
4=AMI (T1/E1)
• line_len is the line length: 10-15 for T1; 8 for E1 with SMB line module; 9 for E1 with RJ-48 line
module
• clk_src is a number specifying the clock source: 1 for loop clock; 2 for local clock
