On some PICs, the behavior aggregate (BA) translation tables are included for every
logical interface (unit) protocol family configured on the logical interface. The proper
default translation table is active even if you do not include any explicit translation tables.
On M40e, M120, M320, and T Series routers with Enhanced IQ (IQE) PICs, or on any
system with IQ2 or Enhanced IQ2 (IQ2E) PICs, you can replace the type-of-service (ToS)
bit value on the incoming packet header on a logical interface with a user-defined value.
The new ToS value is used for all class-of-service (CoS) processing and is applied before
any other CoS or firewall treatment of the packet. The PIC uses the translation-table
statement to determine the new ToS bit values. You can configure a physical interface
(port) or logical interface (unit) with up to three translation tables. The number of frame
relay data-link connection identifiers (DLCIs) (units) that you can configure on each PIC
varies based on the number and type of BA classification tables configured on the
interfaces.
To configure CoS Translation Table in NSM:
Chapter 13: Configuring Class of Service Features
Your Action
1.
In the Name box, enter the name of the
traffic-control profile.
2. Select the scheduler map.
3. Expand traffic-control-profiles.
4. Select the following:
Select Delay Buffer Rate as default value
and set the delay buffer rate.
Select Guaranteed Rate if you do not
configure delay buffer rate. The delay
buffer rate calculation is based on the
guaranteed rate.
NOTE: On LSQ interfaces, you can configure
the guaranteed rate as a percentage from 1
through 100.
On IQ and IQ2 interfaces, you can configure the
guaranteed rate as an absolute rate from 1000
through 160,000,000,000 bits per second.
Select Shaping Rate if you do not
configure delay buffer rate or guaranteed
rate. The delay buffer rate calculation is
based on the shaping rate.
