Catalyst 8540 MSR Enhanced ATM Router Module Features
The Catalyst 8540 MSR enhanced ATM router module offers the following benefits:
•Interoperates with all of the Layer 3 switching interface modules available for the
Catalyst 8540 CSR chassis. For more information on the Catalyst 8540 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 an aggregate switching capacity of 2 Gbps between ATM and Layer 3 ports (2 x
•Simplifies management.
•
•Occupies only one slot in the chassis.
•Supports multiprotocol encapsulation over ATM (RFC 1483) switched virtual connections (SVCs), soft permanent virtual circuits (PVCs) and permanent PVCs with either ATM adaptation layer 5 (AAL5) Subnetwork Access Protocol (SNAP) or AAL5 MUX encapsulation.
•Supports classical ATM over IP (RFC 1577) SVCs and PVCs.
•Standard and extended access control list (ACL) support for IP, and standard ACL support for IPX.
For information configuring on IP ACLs, see Chapter 11, “Using Access Control,” and refer to the “Configuring IP Services” chapter in the Cisco IOS IP and IP Routing Configuration Guide. For information configuring on IPX ACLs, refer to the “Configuring Novell IPX” chapter in the Cisco IOS AppleTalk and Novell IPX Configuration Guide.
