Software Configuration of ATM ISE Line Cards for
Cisco 12000 Series Routers
This feature module describes the software configuration for the Cisco 4-Port ATM Internet Services
Engine (ISE) line cards in the Cisco 12000 Series Router. The line card comes in two variations:
OC-12c/STM-4c and OC-3c/STM-1; otherwise, the features are the same on both cards.
Feature History for the 4-Port ATM ISE Line Card
Release
12.0(25)S

    Be prepared with the information that you will need, such as the interface IP address. The Cisco 12000 Series Router identifies an interface address by its line card slot number and port number, in the format slot/port. Because each 4-Port ATM ISE line card contains four ATM interfaces, the port numbers are 0 to 3.

Two types of token bucket algorithms are in Cisco IOS Release 12.1(5)T: a one-token bucket algorithm and a two-token bucket algorithm. A one-token bucket system is used when the violate-action option is not specified, and a two-token bucket system is used when the violate-action option is specified.
  • Page 96 Software Configuration of ATM ISE Line Cards for Cisco 12000 Series Routers police rate Tokens are updated in the conform bucket. If the previous arrival of the packet was at T1 and the • current arrival of the packet is at T, the bucket is updated with T -T1 worth of bits based on the token arrival rate.
