This chapter describes the steps required to configure the physical interfaces on the ATM switch router. Your switch is configured as specified in your order and is ready for installation and startup when it leaves the factory.
Each port on the port adapter physical interface can be configured to support the following clocking options:
The plug-and-play mechanisms of the ATM switch router allow it to come up automatically. All configuration information for port adapters can be saved between hot swaps and switch reboots, while interface types are automatically discovered by the switch, eliminating mandatory manual configuration.
When you upgrade your system, add components, or customize the initial configuration, refer to the following sections:
To configure the circuit emulation service (CES) T1 and E1 port adapters and the Frame Relay E1 port adapters, see the chapters "Configuring Circuit Emulation Services" and "Configuring Frame Relay-to-ATM Interworking Port Adapter Interfaces."
The ATM switch supports two types of 25-Mbps port adapters: a 4-port version and a 12-port version. The number of ports is determined by the type of cable used with the 25-Mbps port adapters. The cables have a 96-pin Molex connector with a multileg RJ-45 cable assembly. That is, multiple RJ-45 cables branch off from one large 96-pin Molex connector. You can choose either a 4-port version (with four RJ-45 cables) or a 12-port version (with 12 RJ-45 cables). Each 25.6-Mbps ATM port can be used for workgroup links. Each port complies with the ATM Forum PHY standard for 25.6 Mbps over twisted-pair cable.
The plug-and-play mechanisms of the ATM switch allow the switches to come up automatically. All configuration information for the port adapters can be saved between hot swaps and switch reboots, while interface types are automatically discovered by the switch, thereby eliminating mandatory manual configuration.
The ATM switch supports any combination of port adapters. You can configure your switch with up to 32 25-Mbps interface ports with the 4-port 25-Mbps port adapter, or up to 96 25-Mbps interface ports with the 12-port 25-Mbps port adapter.
If ILMI is disabled or if the connecting end node does not support ILMI, the following defaults are assigned to all 25-Mbps interfaces:
For the 12-port 25-Mbps port adapter, the following parameters can be configured on physical ports 0 or 6. Parameters configured on port 0 apply to ports 0 to 5, and parameters configured on port 6 apply to ports 6 to 11. For the 4-port 25-Mbps port adapter, parameters configured on port 0 apply to ports 0 to 4:
To manually change any of the default configuration values, perform the following tasks, beginning in global configuration mode:
| Step | Command | Purpose | ||
|---|---|---|---|---|
| interface atm card/subcard/port | Specifies an ATM interface and enters interface configuration mode. | ||
| atm uni [side network] [type private] [version {3.0 | 3.1 | 4.0}] | Modifies the ATM interface side, type, or version. | ||

The 155-Mbps Synchronous Optical Network (SONET) Synchronous Transport Signal level 3/Synchronous Digital Hierarchy (STS3c/SDH) Synchronous Transport Module level 1 (STM1) port adapter, used for intercampus or wide-area links, has four ports.
You can configure your Catalyst 8540 MSR with any number and type of interfaces required, up to 64 155-Mbps interface ports.
The port adapter supports SC-type and unshielded twisted-pair (UTP) connectors, while receive and transmit LEDs on each port give quick, visual indications of port status and operation.
Traffic pacing allows the aggregate output traffic rate on any port to be set to a rate below the line rate. This feature is useful when communicating with a slow receiver or when connected to public networks with peak-rate tariffs.
You can configure your Catalyst 8510 MSR and LightStream 1010 ATM switch router with any number and type of interfaces required, with up to 32 155-Mbps interface ports.
