ATM Service Provisioning on the IGX
This section provides information on how to provision ATM service on an IGX node. Information in this
section applies to the UXM, and the UXM-E card sets. For more information on these cards, see the
“Universal Switching Module” section on page 2-23 in Chapter 2, “Cisco IGX 8400 Series Cards.”
Before provisioning ATM service, you should perform basic configuration on the node, set up a trunk,
and configure at least one ATM line onto the node.
When provisioning ATM service, you will complete the following tasks:
1. Plan your connections to optimize bandwidth (see the “Calculating and Managing Bandwidth”
section on page 8-8).
2. Determine a traffic class (CoS) for the connection (see the “Setting Up an ATM Connection” section
on page 8-8).
3. Activate and configure the port on the local node.
4. (Optional) Specify a local management interface (LMI, ELMI, or ILMI).
5. (Optional) Configure the CoS queues for each traffic class.
6. (For network topologies utilizing LSCs and LERs) Configure VIs and VSIs.
7. (For network topologies utilizing LSCs and LERs) Apply SCTs to VIs and VSIs.
8. (For network topologies utilizing LSCs and LERs) Re-configure Qbins as necessary.
9. Configure the connection on the line.
