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.
 |
Note This chapter provides advanced configuration instructions for the Catalyst 8540 MSR, Catalyst 8510 MSR, and LightStream 1010 ATM switch routers. For complete descriptions of the commands mentioned in this chapter, refer to the ATM Switch Router Command Reference publication. For hardware installation and cabling instructions, refer to the ATM Port Adapter and Interface Module Installation Guide . |
Each port on the interface module or interface module 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 interface modules can be saved between hot swaps and switch router reboots. The switch router automatically discovers interface types and eliminates 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, refer to "Configuring Circuit Emulation Services." To configure the Frame Relay E1 port adapters, refer to "Configuring Frame Relay to ATM Interworking Port Adapter Interfaces." To configure the T1 and E1 inverse multiplexing over ATM (IMA) port adapters, refer to "Configuring IMA Port Adapter Interfaces." To configure the ATM router modules, refer to "Configuring ATM Router Module Interfaces."
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:
|
Note Pacing might not be configured on any physical port of the 25-Mbps port adapter. |
To manually change any of the default configuration values, perform the following steps, beginning in global configuration mode:
| Command | Purpose | |
|---|---|---|
Step 1 | Switch(config)# interface atm card/subcard/port Switch(config-if)# | Specifies an ATM interface and enters interface configuration mode. |
Step 2 | Switch(config-if)# atm uni [side network] [type private] [version {3.0 | 3.1 | 4.0}] | Modifies the ATM interface side, type, or version. |

You can configure any number and type of interfaces required, up to 64 155-Mbps interface ports on the Catalyst 8540 MSR and up to 32 155-Mbps interface ports on the Catalyst 8510 MSR and LightStream 1010 ATM switch routers.
|
Note The 155-Mbps port adapter supports mixed mode. Port 0 is a single-mode interface and ports 1 through 3 are multimode interfaces. |
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.
