Chapter 3 Preparing AXSM Cards and Lines for Communication
Setting Up Lines
Bringing Up Lines
Installing an AXSM card can add from 1 to 16 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.
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, see the “Planning for Card
and Line Redundancy” section in Chapter 1, “Preparing for Configuration.” For information on
configuring APS lines, see the “Establishing Redundancy Between Two Lines with APS” section later
in this chapter.
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.
mgx8850a.7.PXM.a > cc <slotnumber>
Replace <slotnumber> with the number of the slot in which the AXSM card is installed. Valid slot
numbers are from 1 to 6 and 9 to 14. Verify your card selection by viewing the switch prompt, which
should list the slot number and the AXSM card type.
Step 3 Enter the upln command after the switch prompt.
mgx8850a.10.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 back card port to which the line is connected. Table 3-3 lists the valid bay numbers and line numbers
for each AXSM card. Figure 3-1 illustrates the bay and line numbers used on the Cisco MGX 8850 and
Cisco MGX 8950 switches.
