Cisco Cisco IOS Software Release 12.2 Notas de publicación

This section describes how the Cisco OC-3c/OC-3c NI-2 card was enhanced to support QoS in a fully 
loaded chassis of G.SHDSL SHTU-C (8xG.SHDSL) line cards.

To accommodate these enhancements, the following changes were made to the legacy NI-2 card:

The upstream field programmable gate array (FPGA) was enhanced to support QoS tables for the 
upstream traffic manager (UPTM).

The DSLAM automatically builds the upstream QoS tables using the QoS values defined by 
commands such as atm connection-traffic-table-row and atm pvc. (See the 

 for a list of atm commands used 

to set upstream QoS table values.)

The size of the bootflash memory and main dynamic RAM (DRAM) were increased (see 

The enhanced NI-2 card can be installed in the following Cisco DSLAM chassis:

Cisco 6100 DSLAM
Cisco 6130 DSLAM
Cisco 6015 DSLAM
Cisco 6160 DSLAM
Cisco 6260 DSLAM

 shows the memory enhancements made to the new Cisco OC-3c/OC-3c NI-2 card.

The following list describes the software changes made to accommodate the enhanced NI-2 card:

The show hardware command output displays the new NI-2 card types:

NI2-155MM-155MM2
NI2-155SM-155SM2

The following atm commands were enhanced to accommodate upstream QoS tables. In addition to 
configuring the QoS values for the ATM switch component of the DSLAM, these commands now 
also define the values for the upstream QoS tables.
