Catalyst 8500 Deployment Flexibility

The Catalyst 8500 series can be deployed as a Layer 3 switch

providing nonblocking routing for IP, IPX, and IP multicast while

also offering wire-speed Layer 2 switching for nonroutable

protocols such as NetBIOS and DECnet local-area transport (LAT).

This capability allows network managers to augment their

multiprotocol backbones with the Catalyst 8500 without having to

build parallel networks, as is often required with IP-only switches.

The Catalyst 8500 series can also be deployed as a multiservice

ATM switch or as an integrated Layer 3 and multiservice ATM

switch. This unique ability allows the deployment of hybrid

networks implementing the best of both technologies while

eliminating the need to choose one technology over another.

When deployed with the Switch Route Processor (SRP),

C8510-SRP, the Catalyst 8510 is equipped as a Layer 3 switch only.

When deployed with the Multiservice Switch Route Processor,

C8515-MSRP, the Catalyst 8510 is equipped as a multiservice ATM

switch. Future software enhancements and the addition of an ATM

router module will allow the deployment of multiservice ATM and

Layer 3 interfaces in a single Catalyst 8510 chassis deployed with

the C8515-MSRP.

Likewise, when deployed with Route Processors (RP) and

Switch Processors (SP), C8541-RP and C8542-SP, the Catalyst

8540 is equipped as a Layer 3 switch only. When deployed with

Multiservice Route Processors (MSP) and Multiservice Switch

Processor (MSP), C8545-MRP and C8546-MSP respectively, the

Catalyst 8540 is equipped as a multiservice ATM switch. Future

software enhancements and the addition of an ATM router module

will allow the deployment of Multiservice ATM and Layer 3

interfaces in a single Catalyst 8540 chassis deployed with the

C8545-MRP and C8546-MSP.
