Chapter 3 Installing the IGX
Setting Up a UXM-E
To specify the range of ports for an IMA line, you can use either Cisco WAN Manager or the
command-line interface (CLI). To define an IMA line on the CLI, use the upln command:
upln slot.group-member
For example, you could enter upln 8.1–4. Subsequently, you would refer to this physical line by using
only the slot number and first group member—8.1 in this example—when you use commands, such as
upln, dnln, cnfln, and so on. Following the activation of an IMA line group, the logical port will be
created with the primary line port as the port number.
Commands for viewing IMA line information also include dsplncnf, dsplns, dspports, dspport,
dspphyslnstathist and dspphyslnstatcnf.
Note The UXM-E IMA ports on an IGX, will interoperate with an IMA compliant router or a device that
supports the ATM Forum Compliant IMA Protocol, Version 1.0.
Bringing Up a UXM-E in UNI or NNI Port Mode
If you are not familiar with card insertion, see the “IGX Configuration Summary” section on page 3-59.
To attach the cables:
Step 1 Bring each cable through the opening at the top or bottom of the cabinet (whichever is appropriate) and
along the back of the IGX enclosure.
Step 2 If the unit has the optional cable manager, you can use it to help route the cables.
Step 3 Connect the cables to the connectors on the back card.
To activate a port-mode UXM-E:
Step 1 Verify the correct card locations in both the local and remote nodes (using the dspcds command).
Step 2 Activate each line by using the upln command. Run this command on the nodes at both ends of the line.
Use the vt command to reach the far-end node to run commands. When you activate the first line with
the upln command, the UXM-E goes into port mode.
Step 3 At the near-end and far-end nodes, use the cnfln command to configure line parameters as required. Each
line comes up with a default configuration, but you can change the configuration with the cnfln
command.
Step 4 Optionally, you can specify Y-cable redundancy with the addyred command.
Step 5 Use the upport command at the near-end and far-end nodes to activate (up) the logical port. Use vt to
reach the far-end node. Activating the port makes it a usable resource, so you can subsequently add
connections through Cisco WAN Manager or the CLI (using the addcon command).
Step 6 Use the cnfport command at the near-end and far-end nodes to configure each logical port. Applicable
parameters are the choice of UNI or NNI cell header, an enable for Local Management Interface (LMI)
or Interim Local Management Interface (ILMI) protocol or no protocol, and an enable for the %util
parameter.
Step 7 If you do not want the defaults for the queue depths and high and low discard eligibility thresholds, use
the cnfportq command to configure parameters for the CBR, VBR, and ABR queues.
