Hardware and Software Restrictions of the ATM Router Module

Catalyst 8510 MSR and LightStream 1010 ATM Router Module Features

The Catalyst 8510 MSR and LightStream 1010 ATM router module offers the following benefits:

•Interoperates with all of the Layer 3 switching interface modules available for the

Catalyst 8510 CSR chassis. For more information on the Catalyst 8510 CSR Layer 3 interface modules, refer to the ATM and Layer 3 Module Installation Guide.

•Provides an integrated high performance link between ATM and Layer 3 cards. The ATM router module provides a switching capacity of 1 Gbps between ATM and Layer 3 ports. Data transfers to the switch core at the rate of 1 Gbps.

•Simplifies management.

•Hot-swappable.

•Occupies only one slot in the chassis.

•Supports RFC 1483 SVCs and PVCs with AAL5 SNAP encapsulation.

•Supports RFC 1577 SVCs and PVCs.

•Supports OAM-based PVC management.

•Supports BVI.

•Supports IRB.

•Supports VBR.

The ATM router module has no external interfaces. All traffic is sent and received through internal interfaces to the switching fabric. The Catalyst 8510 MSR and LightStream 1010 ATM router module has one internal port.

Hardware and Software Restrictions of the ATM Router Module

Hardware Restrictions

The following hardware restrictions apply to the Catalyst 8540 MSR, Catalyst 8510 MSR, and LightStream 1010 ATM router modules, and the Catalyst 8540 MSR enhanced ATM router modules:

•You can install the ATM router module in any slot except a route processor slot, and, in the case of the Catalyst 8540 MSR, a switch processor slot.

•The ATM router module is only supported on LightStream 1010 ATM switches with multiservice ATM switch route processor with FC-PFQ and the Catalyst 8510 MSR system software image.

•You can install up to two ATM router modules per chassis.

•When you hot swap an ATM router module, wait one minute after removing the module before inserting a new module.

Note The ATM router module is only supported on ATM switches which have multiservice ATM switch processor installed.
