Catalyst 8540 ATM Router Module
Feature Support
The following features and capabilities are supported on the
ARM module:
Table 1: Feature Summary
Integrated Layer 3 and ATM
The ARM is unique in that it allows Layer 3 traffic to pass
seamlessly between ATM and Layer 3 interfaces. The benefit
to the customer is that wire-speed Layer 3 switching between
frame (Gigabit Ethernet/Fast Ethernet) ports, ATM switching
between ATM ports, and high-speed frame/ATM
interworking are combined in a single chassis. The result is
fewer products in the network, simplified network designs,
and a lower total cost of ownership.
The ARM can be configured to support either Request
for Comments (RFC) 1483 or LANE for providing
integrated Layer 3 and ATM services.
RFC 1483
ARM support of the Internet Engineering Task Force (IETF)
specification RFC 1483, “Multiprotocol Encapsulation over
ATM Adaptation Layer 5” on the 8540 MSR includes:
• LLC/SNAP encapsulation
• IP/IPX
• IP multicast
