Configuring Service On An Eight-Port Cesm - Cisco MGX-FRSM-2CT3 Configuration Manual

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 PXM)
•
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 8850 Wide Area Edge Switch 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
Step 2
addln <line number>
where line number is in the range 1–8. You can modify line characteristics with cnfln.
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-signaling]
•
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
RJ48 line module
•
clk_src is a number specifying the clock source: 1 for loop clock, 2 for local clock
•
E1-signalling specifies the E1 signaling. The possible entries are:
— CAS, which specifies CAS and no CRC
— CAS_CRC, which specifies CAS with CRC
— CCS, which specifies CCS and no CRC
— CCS_CRC, which specifies CCS with CRC
— CLEAR: CLEAR channel
