Cisco ATM Services (AXSM) Configuration Guide and Command Reference for MGX Switches
Release 5.2, Part Number OL-6484-01 Rev. C0, September 2005
Chapter 2 Preparing AXSM Lines for Communication
General AXSM Provisioning Procedures
Bringing Up Lines
Installing an AXSM card can add from 1 to 32 lines to your switch. You must bring up a line before you
can configure the line or provision services on the line.
Before a line is brought up, or after it is brought down, the switch does not monitor the line. The AXSM
port status light for the line is unlit, and all line alarms are cleared.
When you bring up a line, the switch starts monitoring the line. The AXSM port status light is green
when physical layer communications are established with a remote switch. If physical layer
communications problems are detected, the port status light turns red, and alarms are reported. The port
status light turns yellow when physical layer communications problems are detected on the remote
switch.
Note APS protection lines for intracard redundancy should be left down. APS automatically brings up each
line at the appropriate time. For general information on APS line redundancy, refer to Chapter 2 of the
the Cisco MGX 8800/8900 Series Configuration Guide, Release 5.2. For information on configuring
APS lines, see the “Establishing Redundancy between Two Lines with APS” section on page 2-14.
Tip To minimize the number of alarms and failed port status lamps (which display red), keep lines down until
they are ready for operation.
To bring up a line on the switch, use the following procedure.
Step 1 Establish a configuration session using a user name with GROUP1 privileges or higher.
Step 2 Select the card on which you want to bring up a line with the cc command.
M8950_DC.5.AXSM.a > cc < slotnumber >
Step 3 Enter the upln command:
M8950_DC.5.AXSM.a > upln < bay . line >
Replace <bay> with 1 if the line is connected to a back card in the upper bay, or replace it with 2 if the
line is connected to a back card in the lower bay. Replace <line> with the number that corresponds to
the line you want to configure.
Table 2-3 lists the valid bay numbers and line numbers for each AXSM card. Figure 2-1 illustrates the
bay and line numbers used on the Cisco MGX 8850(PXM45), MGX 8950, and MGX 8880 switches.
