Release Notes for Cisco 7000 Family for Cisco IOS Release 12.1 T
78-10811-05
New and Changed Information
Class-Based Ethernet CoS Matching & Marking
Platforms: Cisco 7200 series and Cisco 7500 series routers
The Class-Based Ethernet Class of Service (CoS) Matching & Marking extends IOS capabilities to
match packets by looking at the CoS value of the packet and mark packets with user defined CoS values.
This feature can be used for L2 CoS to L3 TOS mapping. CoS Matching & Marking can be configured
via the IOS QoS Mod CLI framework.
Class-Based Quality of Service Management Information Base
Platforms: Cisco 7200 series with NPE150 or higher for T1/E1/Ethernet rates, Cisco 7200 series with
NPE200 or higher for T3 rates, Cisco 7500/ Route Switch Processor (RSP)
The Class-Based Quality of Service Management Information Base (Class-Based QoS MIB) provides
read access to class-based QoS configurations. This MIB also provides QoS statistics information based
on the Modular QoS CLI, including information regarding class map and policy map parameters.
This Class-Based QoS MIB is actually two MIBs: CISCO-CLASS-BASED-QOS-MIB and
CISCO-CLASS-BASED-QOS-CAPABILITY-MIB.
Closed User Group Selection Facility Suppress Option
Platforms: Cisco 7100 series, Cisco 7200 series and Cisco 7500 series routers
A closed user group (CUG) selection facility is a specific encoding element that allows a destination
data terminal equipment (DTE) to identify the CUG to which the source and destination DTEs belong.
The Closed User Group Selection Facility Suppress Option feature enables a user to configure an X.25
data communications equipment (DCE) interface or X.25 profile with a DCE station type to remove the
CUG selection facility from incoming call packets destined for the preferential CUG only or for all
CUGs. You can also remove the selection facility from a CUG with outgoing access (CUG/OA).
Configurable per ATM-VC Hold Queue Size
Platforms: Cisco 7200 series routers
Using the Configurable per ATM-VC Hold Queue Size feature, customers can specify the number of
packets contained in the hold queue, per virtual circuit (VC), on ATM adapters that support per-VC
queueing. By default, the queueing mechanism in use determines the size of the hold queue, and,
therefore, the number of packets contained in the queue. Customers can expand the default hold queue
size and change (or vary) the number of packets the queue can contain. With this new feature, the hold
queue can contain a maximum of 1024 packets. This feature provides a new command, called
vc-hold-queue, with which the customer can specify the number of packets contained in the per-VC
hold queue. This can be a number from 5 to 1024.
DiffServ Compliant WRED
Platforms: Cisco 7200 series and Cisco 7500 series routers
The DiffServe Compliant WRED feature extends the functionality of WRED (weighted random early
detection) to enable support for Differentiated Services (DiffServ) and Assured Forwarding (AF) Per
Hop Behavior (PHB). This feature enables WRED to be compliant with the DiffServ standard and the
AF PHB standard being developed by the Internet Engineering Task Force (IETF). Customers can
implement AF PHB by coloring packets according to DSCP values and then assigning preferential drop
