Setting Up a UXM-E
Setting Up a UXM-E
This section consists of descriptions of how to set up a port-mode UXM-E and a trunk-mode UXM-E. The descriptions consist of the steps for attaching cables and entering commands at the command line interface (CLI). For detailed information regarding the UXM-E, refer to the Cisco IGX 8400 Series Reference. The Cisco IGX 8400 Series Reference contains crucial information on, for example, supported endpoints, connection types, allocation of cellbus bandwidth, and the logical trunk feature called Inverse Multiplexing over ATM (IMA).
You can specify the mode of the UXM-E through Cisco WAN Manager or the CLI. The entire UXM-E card set goes into the mode determined by the first port you activate. If you activate a logical port to be a trunk by using the uptrk command, for example, the UXM-E goes into trunk mode. If you use upln to activate a line as a UNI port to CPE or an NNI to another network, the UXM-E goes into port mode.
For a summary of commands you use to bring up an IGX node, refer to the section “IGX
Configuration Summary” on page 49.
Bringing Up a UXM-E in UNI or NNI Port Mode
If you are not familiar with card insertion, see the section “Preparing the Cards” page 1.
To attach the cables:
Step 1 Bring each cable through the opening at the top or bottom of the cabinet (however 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 (dspcds).
Step 2 Activate each line by using upln. Execute this command on the nodes at both ends of the line. Use the vt command to reach the far-end node to execute commands. When you activate the first line through upln, the UXM-E goes into port mode.
Step 3 At the near and far-end nodes, use cnfln to configure line parameters as required. Each line comes up with a default configuration, but you can change the configuration with cnfln .
Step 4 Optionally, you can specify Y-cable redundancy with the addyred command.
Step 5 Use upport at the near and far-end nodes to activate the logical port. Use vt to reach the far-end node. Upping the port makes it a usable resource, so you can subsequently add connections through Cisco WAN Manager or the CLI (addcon).
Step 6 Use cnfport at the near and far-end nodes to configure each logical port. Applicable parameters are the choice of UNI or NNI cell header, an enable for LMI or ILMI protocol or no protocol, and the 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 cnfportq to configure parameters for the CBR, VBR, and ABR queues.
Step 8 Optionally, you can use cnfabrparm to configure additional parameters for ABR traffic.
The cnfabrparm parameters are CI control and egress explicit rate stamping.
Step 9 Optionally, you can configure a UXM-E port as a clock source. Use cnfclksrc.
