This chapter is a reference for the ingress Quality of Service (QoS) and hierarchical QoS.
• queue-limit
bandwidth
Use this command to allocate a minimum percentage of the interface bandwidth to a queue.
Use the no command to remove a bandwidth configuration.
Command Syntax
bandwidth (<1-1000000000> (kbps|mbps|gbps) | percent <1-100>)
no bandwidth
Parameters
<1-1000000000>
Bandwidth value
kbps
Units in kilobits/sec.
mbps
Units in megabits/sec.
gbps
Units in gigabits/sec.
percent <1-100>
Specify the percentage from 1 to 100.
Default
No default value is specified
Command Mode
Policy-class-map mode
Applicability
This command was introduced before OcNOS version 1.3.
This command applies only to the Trident II, Trident II+, and Tomahawk platforms.
Examples
(config)# policy-map type queuing PQOS
(config-pmap-que)# class type queuing 1p7q4t-out-pq1
(config-pmap-c-que)# bandwidth 10 mbps
class-map type qos
Use this command to create a class-map of type qos.
Use the no command to remove a class-map.
Note:
• Class-map without any match qualification behaves similar to default class by matching all the packets on the interface it is attached via service policy.
• In a class-map, adding or deleting match criteria with misconfiguration will have silent exit and will not proceed with operation.
Command Syntax
class-map (type qos|) (match-any|match-all|) NAME
no class-map (type qos|) (match-any|match-all|) NAME
Parameters
type qos
Ingress/egress class map.
NAME
Specify the class map name (Max Size 32)
match-any
Match any parameter (boolean OR)
match-all
Match all parameters (boolean AND)
Default
By default, match type is match-all for any class-map
Command Mode
Configuration Mode
Applicability
This command was introduced before OcNOS version 1.3.
Examples
#configure terminal
(config)# class-map type qos C_QOS1
class-map type queuing
Use this command to create a class-map of type queuing.
Use the no command to remove a class-map.
Note: Class-maps with no action are treated as incomplete configuration and don't take any effect until the action is added. Class-map deletion is not allowed if it is referenced by any policy-map.
Command Syntax
class-map type queuing (match-any|) NAME
no class-map type queuing (match-any|) NAME
Parameters
type queuing
Egress class map
NAME
Specify the class map name (Max Size 32)

class type qos
Use this command to add a QoS class-map to a qos policy map.

Note: Implicit priority of the classes in a policy-map will be calculated based on the number of matches with VLAN match given lower weight-age over other matches. In case of classes with conflicting matches, it is not guaranteed which class the traffic would hit. Users are recommended to use priority in such cases.

Usage
Traffic policing is based on the concept of marking IP packets, and then metering the packets in relation to how they are marked. This is called the “Two Rate Three Color Marker (trTCM)” process.
The Two Rate Three Color Marker (trTCM) meters an IP packet stream, and marks its packets as either green, yellow, or red. A packet is marked RED if it exceeds the Peak Information Rate (PIR). Otherwise it is marked either YELLOW or GREEN depending on whether it exceeds or does not exceed the Committed Information Rate (CIR). The trTCM is useful, for example, for ingress policing of a service, where a peak rate needs to be enforced separately from a committed rate.
The Meter meters each packet and passes the packet and the metering result to the Marker. The Meter operates in one of two modes – Color-Blind or Color-Aware. In the Color-Blind mode, the Meter assumes that the packet stream is uncolored.In the Color-Aware mode, the Meter assumes that some preceding entity has pre-colored the incoming packet stream so that each packet is either GREEN, YELLOW, or RED.
The following describes the equations used to determine the BC an BE values:
Note: CIR, PIR, BC, and BE values are all in kbits/sec.
=================
BC = CIR * 5 / 1000;
Range check [64kbytes-256mbytes]
if (BC / 8) < 64)
then BC = 64 * 8;
else if (BC / 8) > 256000)
then BC = 256000 * 8;
=================
Same calculation for BE, as well.
Note: If the PIR value is not mentioned in the configuration, then the CIR value itself is considered for BE calculation.
=================
BE = PIR * 5 / 1000;
Range check [64kbytes-256mbytes]
if (BE / 8) < 64)
then BE = 64 * 8;
else if (BE / 8) > 256000)
then BE = 256000 * 8;
==================
For example:
Configure: police CIR 1 mbps
Hardware: CIR = 1000kbits/sec , BC = 512kbits, BE = 512kbits
Configure: police CIR 1 mbps PIR 200 mbps
Hardware: CIR = 1000kbits/sec, BC = 512kbits, PIR = 200000kbits/sec, BE = 1000kbits

percent <1-100>
Specify the percentage from 1 to 100.
Default
No default value is specified
Command Mode
Policy-class-map mode
Applicability
This command was introduced before OcNOS version 1.3.
Examples
(config)# policy-map type queuing my_queue
(config-pmap-que)# class type queuing PQOS
(config-pmap-c-que)# shape percent 25
shape rate
Use this command to configure shaping on an egress port to impose a maximum rate on it.
Use the no form of the command to remove a shaping configuration.
Command Syntax
shape rate <1-1000000000> (kbps|mbps|gbps) burst SHAPE_BURST_RATE
no shape rate
Parameters
<1-1000000000>
Average rate for shaping in the following range:
8 kbps to 1000 gbps for Trident3
1 kbps to 1000 gbps for other XGS platforms
kbps
Units of kbps per second.
mbps
Units of mbps per second.
gbps
Units of gbps per second.
SHAPE_BURST_RATE
The burst size allowed by the traffic shaper. It determines the maximum amount of data to send or receive before shaping the traffic per the specified rate..
The burst value in kbits in the following range::
<2-1000000> for Trident3 and tomahwak
<1-1000000> for other XGS platforms
The limitation of 1000000 kbits is often a default or practical limit set by the network device or software. This limit ensures that bursts of traffic beyond this size are controlled to prevent network congestion or degradation of service quality. It is the maximum value supported by the hardware.
Default
NA
Command Mode
Interface mode
Applicability
This command was introduced in OcNOS version 1.3.8.
Examples
(config)#interface xe11
(config-if)#shape rate 100 mbps burst 20

show running-config cpu-queue
Use this command to display details about CPU queue information based on processes running.
Command Syntax
show running-config cpu-queue
Parameters

Applicability
This command was introduced before OcNOS version 1.3.8
Example
#show running-config | in cpu-queue
cpu-queue sflow rate 10000 no-monitor

storm-control
Use this command to set the rising threshold level for broadcast, multicast, or destination lookup failure traffic. The storm control action occurs when traffic utilization reaches this level.
Storm control is used to block the forwarding of unnecessary flooded traffic. A packet storm occurs when a large number of broadcast packets are received on a port. Forwarding these packets can cause the network to slow down or time out.
Use the no form of this command to disable storm control.
Command Syntax
storm-control (errdisable|((broadcast|multicast|dlf) (level LEVEL | <0-4294967294>
(kbps|mbps|gbps|fps) burst-size <32-128000>)))
no storm-control (errdisable|broadcast|multicast|dlf)
Parameters
errdisable
Error disable interface on storm control
broadcast
Broadcast rate limiting.
multicast
Multicast rate limiting.
dlf
Destination lookup failure limiting.
level
Sets the percentage of the threshold.
LEVEL
The percentage of the threshold; percentage of the maximum speed (pps) of the interface <0.0000-1000.0000>.
<0-4294967294>
Sets absolute threshold value <0-1000000000>
kbps
specifies the units of Kilobits per second.
mbps
specifies the units of Megabits per second.
gbps
specifies the units of Gigabits per second.
fps
specifies the units of Frames per second.
burst-size
