ATM Overhead Accounting

Cisco IOS Release: Release 12.2(28)SB

Description: The ATM Overhead Accounting feature was introduced on the PRE2 to enable the router

to account for various encapsulation types when applying QoS to packets. The router uses the

encapsulation type you configure to calculate the ATM overhead per packet.

Cisco IOS Release: Release 12.2(33)SB

Description: This feature was enhanced on the PRE3 to allow a user-defined number of overhead bytes.

Cisco IOS Release: Release 12.2(33)SB

Description: The Ethernet Overhead Accounting feature was introduced on the PRE2, PRE3, and PRE4

to enable the router to account for downstream Ethernet frame headers when applying shaping to

packets. A user-defined offset specifies the number of overhead bytes the router is to use when

calculating the overhead per packet.

Cisco IOS Release: Release 12.2(28)SB

Description: The Traffic Shaping Overhead Accounting for ATM feature was introduced on the PRE2

to enable the broadband access system (BRAS) to account for ATM encapsulation on the subscriber line

and the overhead added by cell segmentation. This enables the service provider to prevent overruns at

the subscriber line and ensures that the router executes QoS features on the actual bandwidth used by

ATM subscriber traffic.

Cisco IOS Release: Release 12.2(31)SB2

Description: This feature was introduced on the PRE3.

Cisco IOS Release: Release 12.2(33)SB
