Step Description Command Keys
22 Specify GRED (Generalized Random
Early Detection) parameters (if
required). esr(config-class-policy-map)#
random-detect precedence
<PRECEDENCE><LIMIT><MAX><MI
N><PROBABILITY> <PRECEDENCE> –
IPPrecendence value [0..7];
<LIMIT> – limited size of a
queue in bytes, takes values of
in the range of [1..1000000];
<MAX> – maximum size of a
queue in bytes, takes value in
the range of [1..1000000];
<MIN> – minimum size of a
queue in bytes, takes value in
the range of [1..1000000];
<PROBABILITY> – probability
of packet drop, takes values of
[0..100].
When specifying the values, the
following rules should be
fulfilled:
<MAX>> 2 * <MIN>
<LIMIT>> 3 * <MAX>
23 Enable tcp headers compression
protocol for the certain class traffic (if
required). esr(config-class-policy-map)#
compression header ip tcp
24 Enable QoS on the interface/tunnel/
network bridge. esr(config-if-gi)# qos enable
25 Define the QoS policy on a configured
interface/tunnel/network bridge to
classify input and prioritize output
traffic. esr(config-if-gi)# service-policy
{ input | output } <NAME> <NAME> – QoS policy name,
set by the string of up to 31
characters.
10.2.2 Configuration example
Objective:
Classify incoming traffic by a subnet (10.0.11.0/24, 10.0.12.0/24), label it by DSCP (38 and 42) and segregate
by a subnet (40Mbps and
60Mbps), limit general bandwidth to 250Mbps, process the rest of traffic using SFQ mechanism.
