This chapter describes the ATM router modules that are supported in the following systems:
 |
Note The Catalyst 8510 MSR and LightStream 1010 ATM router modules are not supported in the Catalyst 5500. |
This chapter includes the following sections:
The Catalyst 8540 MSR, Catalyst 8510 MSR and LightStream 1010 ATM switch routers equipped with ATM router module functionality provide Ethernet-ATM and ATM-ATM bridging and routing. The ATM router module offers interoperability between the Layer 3 switching interface modules used in the Catalyst 8540 CSR and the ATM port adapters and interface modules used in the Catalyst 8540 MSR chassis, and between the Layer 3 switching interface modules used in the Catalyst 8510 CSR and the ATM port adapters used in the Catalyst 8510 MSR and LightStream 1010 chassis. You can therefore combine Layer 3 and ATM port adapters and interface modules in a Catalyst 8540 MSR chassis equipped with the ATM router module. The Catalyst 8510 MSR and LightStream 1010 ATM switch routers can use Catalyst 8510 CSR interface modules.
The ATM router module cannot operate with feature card per-class queuing (FC-PCQ) on the processor card. FC-PCQ and FC-PFQ are two types of daughter cards for the processor card. FC-PCQ provides a subset of the ATM Forum traffic management features provided by FC-PFQ. Refer to the Processor Installation Guide for additional information.
|
Note The ATM router module is only supported on the ATM switches which have ASP-C with FC-PFQ installed. |
|
Note For information on how to configure the Layer 3 modules that interoperate with the ATM router module in the Catalyst 8540 MSR chassis, refer to the Catalyst 8540 Campus Switch Route Processor and Interface Module Installation Guide and the Layer 3 Software Feature and Configuration Guide. For information on the Catalyst 8510 CSR and the LightStream 1010 ATM switch routers, refer to the Catalyst 8510 Route Processor and Interface Module Installation Guide. |
The Catalyst 8540 MSR ATM router module has two internal interfaces across the backplane. The Catalyst 8510 MSR and LightStream 1010 ATM router module has one internal interface across the backplane. Each interface provides switching at 1 Gbps between Layer 2 and Layer 3 in the ATM switch.
The ATM router module is a full-width module that occupies the entire slot in the ATM switch. (See Figure 15-1.) You can install up to two ATM router modules in slots numbered 0-3 and 9-12 in the Catalyst 8540 MSR chassis. You can install only one ATM router module in slots 0, 1, 3, and 4 in the Catalyst 8510 CSR and LightStream 1010 chassis.
|
Note The ATM router module is hot-swappable. When hot swapping an ATM router module, wait 1 minute after removing the module and installing a new module. |
You can use the ATM router module for high-speed enterprise campus and metropolitan-area networks. The Catalyst 8540 MSR, Catalyst 8510 MSR and LightStream 1010 ATM switch routers equipped with the ATM router module are an ideal solution where an ATM infrastructure already exists or where ATM is the desired backbone solution. The ATM router module performs Gigabit Ethernet and ATM internetworking seamlessly on a single platform. You can use the ATM router module in campuses that are migrating from ATM to Gigabit Ethernet. The ATM router module allows you to use Gigabit Ethernet for wiring closet uplinks in an existing ATM backbone.
The Catalyst 8540 MSR, Catalyst 8510 MSR and LightStream 1010 ATM switch routers equipped with the ATM router module are used either as a core or an edge devices in an ATM network. Figure 15-2 shows a sample network with a Catalyst 8540 MSR.
The status LED provides information for the internal interfaces on the ATM router module. The LEDs are shown in Figure 15-3 and described in Table 15-1.
