Overview of the ATM Router Module
•IP fragmentation support.
•IP 6-path load balancing support.
•Supports OAM-based PVC management.
•Supports integrated routing and bridging (IRB).
•Supports LANE clients (LECs).
•Supports Soft PVCs.
•Supports VBR.
•Supports Shaped Tunnels.
•Supports a maximum of 8192 VCs.
•LECs and RFC 1483 PVCs can both be configured on different subinterfaces of the same main
interface.
Note Catalyst 8540 MSR enhanced ATM router module supports LANE clients from IOS release 12.1(20)EB.
The ATM router module has no external interfaces. All traffic is sent and received through internal
interfaces to the switching fabric. The Catalyst8540 MSR enhanced ATM router module has two
internal ports.
Catalyst 8540 MSR ATM Router Module Features
The Catalyst 8540 MSR ATM router module offers the following benefits:
•Interoperates with all of the Layer3 switching interface modules available for the
Catalyst 8540 CSR chassis. For more information on the Catalyst8540 CSR Layer 3 interface
modules, refer to the ATM and Layer3 Module Installation Guide.
•Provides an integrated high performance link between ATM and Layer 3 cards. The ATM router
module provides an aggregate switching capacity of 2 Gbps between ATM and Layer 3 ports
(2 x 1-Gbps interfaces per module). Data transfers to the switch core at the rate of 1Gbps.
•Simplifies management.
•Hot-swappable.
•Occupies only one slot in the chassis.
•Supports LANE clients (LECs).
•Supports RFC 1483 SVCs and PVCs with AAL5 SNAP encapsulation.
•Supports RFC 1577 SVCs and PVCs.
•Supports Soft PVCs
•Supports VBR
•Supports Shaped Tunnels
•Supports OAM-based PVC management.
•Supports BVI.
•Supports IRB.
