Cisco Systems 8540 Manual De Usuario

The ATM uplink interface module does not work in a Catalyst 8540 MSR when the ATM
router module is present.

This section describes the default configuration of the ATM uplink interface, initial configurations you
should perform for a newly installed interface, and optional configurations you can do to customize the
interfaces to the requirements of your network.

The ATM uplink interface module consists of one OC-12c or OC-3c port and one
enhanced Gigabit Ethernet port. For instructions on configuring the enhanced Gigabit
Ethernet interface, see the “About the Enhanced Gigabit Ethernet Interfaces (Catalyst
8540)” section on page 4-5.

The following steps provide on overview of configuring an ATM uplink from the switch router to the
ATM network:

Configure the ATM uplink interface:

Enable the ATM interface.

Customize the configuration by configuring PVCs and SVCs.

You must configure at least one PVC or SVC. The VC options you configure must match in three
places: on the switch router, on the ATM switch, and at the remote end of the PVC or SVC
connection.

Configure the ATM switch to which the ATM uplink connects.

On power up, the ATM uplink interface is shut down. When you enter the no shutdown command, the
interface is enabled with the default configuration values shown in Table 4-4.
