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 steps, 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 routers with any number and type of interfaces required, with up to 32 155-Mbps interface ports.

The ATM router module allows you to integrate Layer 3 switching and ATM switching within a single chassis, which eliminates the need to purchase a separate chassis for each technology. When the ATM router module is installed, you no longer need to choose either Layer 3 or ATM technology, as is frequently the case with enterprise campus and MAN applications. You can have both Layer 3 and ATM technologies within the same multiservice ATM switch router chassis.
The ATM router module separates the control and data path so that all LANE control messages are handled by the ATM switch processor, and data messages are switched on the ATM router module port. The LEC is configured on the ATM router module interface, but control message traffic is sent to the ATM switch processor by the ATM router module. All control signals are routed by the ATM router module to the appropriate VCs.
The ATM router module offers the following benefits:
The following hardware restrictions apply:
The following software restrictions apply:
The only features you can configure directly on the ATM router module interfaces are:
Otherwise, the ATM router module operates as a passive device.
The ATM router module has two internal interfaces, but no external ports. Use the interface atm card/subcard/port command to specify these interfaces.
This section describes the default ATM router module interface configuration and how to change the configuration manually.
The following defaults are assigned to both ATM router module interfaces:
To manually change the default configuration values, perform the following steps, beginning in global configuration mode:
| Step | Command | Purpose | ||
|---|---|---|---|---|
| interface atm card/subcard/port | Specifies an ATM interface and enters interface configuration mode. | ||
| atm maxvci-bits max-vci-bits | Modifies the maximum number of active VCI bits. |
The following example shows how to change the default number of active VCI bits:
Switch(config)# interface atm 0/0/0 Switch(config-if)# atm maxvci-bits 10
The procedures for configuring LANE clients on the ATM router module are the same as the configuration for LANE clients on the route processor, with one exception. To specify an ATM router module interface, rather than the route processor interface, use the interface atm card/subcard/port command. On the route processor, you would use the interface atm 0 command.
To specify the ATM router module interface, use the following command in global configuration mode:
| Command | Purpose |
|---|---|
interface atm card/subcard/port[.subinterface#] | Specifies the ATM interface on the ATM router module and enters interface configuration mode. |
The following example shows how to configure two LECs on an ATM router module interface:
Switch# configure terminal Switch(config)# interface atm 1/0/0.4 multipoint Switch(config-subif)# ip address 40.0.0.1 255.0.0.0 Switch(config-subif)# lane client ethernet VLAN4 Switch(config-subif)# exit Switch(config)# interface atm 1/0/0.5 multipoint Switch(config-subif)# ip address 50.0.0.1 255.0.0.0 Switch(config-subif)# lane client ethernet VLAN5 Switch(config-subif)# exit Switch(config)# router ospf 1 Switch(config-router)# network 40.0.0.0 0.255.255.255 area 0 Switch(config-router)# network 50.0.0.0 0.255.255.255 area 0
For more information on configuring LANE clients on ATM router module interfaces, see the section "Configuring a LAN Emulation Client on the ATM Switch Router" in the chapter "Configuring LAN Emulation."
