Chapter 3 Provisioning PXM1E Communication Links
General PXM1E Configuration Procedures
Step 1 Establish a configuration session with the Cisco MGX 8850 (PXM1E) or the Cisco MGX 8830 using a
user name with GROUP1 privileges or higher.
Step 2 Enter the upln command to create an interface between the PXM1E card on the Cisco MGX 8850 or
Cisco MGX 8830 switch, and the UXM card on the IGX switch.
Step 3 If you are creating a non-IMA interface, enter the addport command. If you are creating an IMA
interface, enter the addimagrp, addimalink and addimaport commands, as described in the
“Configuring Inverse Multiplexing for ATM” section earlier in this chapter.
Tip Remember that you cannot configure a line until you have brought it up as described in
“Bringing Up Lines,” which appears earlier in this chapter.
Step 4 At the active PXM1E, enter the addlmi <ifNum> <type> command to designate the interface as a feeder.
Replace <ifNum> with the logical interface number, in the range from 1 through 60. Replace <type> with
1 to specify that the interface you are configuring is a feeder.
Step 5 Enter the dsppnport to ensure that the port you are configuring is down. It the port is up, enter the
dnpnport command to bring it down.
Note The port you are configuring must be down before you specify port signaling.
Step 6 Enter the cnfpnportsig <portid> -cntlvc ip command to define the signaling protocol used on the trunk.
Replace <portid> using the format slot[:bay].line[:ifNum].
Step 7 Enter the uppnport <portid> command to bring the port up. Replace <portid> using the format
slot:bay.line:ifNum. Table 3-11 describes these parameters.
Step 8 Establish a configuration session with the Cisco MGX 8850 (PXM1E) or the Cisco MGX 8830 using a
user name with GROUP1 privileges or higher.
Step 9 At the UXM switch prompt, enter the cnfswfunc command to make the IGX node a feeder.
Step 10 Enter the uptrk create a standard trunk or an IMA trunk between the UXM on the IGX and the PXM1E
on the Cisco MGX switch.
Step 11 Enter the cnftrk configure the trunk.
Note The configuration on the UXM end of the trunk must be identical to the configuration on the
PXM1E end of the trunk.
Step 12 Enter the dsptrk command to ensure that the trunk you just configured is functioning properly.
Note For more information on the IGX switch and the IGX CLI, refer to the Cisco IGX 8400 Series
Provisioning Guide, Release 9.3.30.
