Field	Description
Interface	Port name identified by port type and port number

qos gts

Syntax

qos gts queue queue-number cir committed-information-rate [ cbs committed-burst-size ]

undo qos gts queue queue-number

View

Ethernet interface view, port group view

Default Level

2: System level

Parameters

queue queue-number: Specifies a queue by its number, which ranges from 0 to 7.

cir committed-information-rate: Specifies the committed information rate (CIR) in kbps.

cbs committed-burst-size: Specifies the CBS (in bytes), which ranges from 4096 to 268435456 and must be a multiple of 4096.

If the cbs keyword is not specified, the default CBS is 62.5 ms × committed-information-rate and must be a multiple of 4096. If 62.5 ms × committed-information-rate is not a multiple of 4096, the default CBS is the multiple of 4096 that is bigger than and nearest to 62.5 ms × committed-information-rate. The maximum CBS is 268435456. For example, if the CIR is 640 kbps, then 62.5 ms × CIR is 62.5 ms × 640 = 40000. As 40000 is not a multiple of 4096, 40960, which is the multiple of 4096 that is bigger than and nearest to 40000, is taken as the default CBS.

Description

Use the qos gts command to configure traffic shaping.

Use the undo qos gts command to remove the traffic shaping configuration.

In Ethernet interface view, the configuration takes effect on the current port. In port group view, the configuration takes effect on all ports in the port group.

Examples

# Configure traffic shaping on GigabitEthernet 2/0/1 to limit the outgoing traffic rate of queue 2 to 640 kbps.

Default Level

2: System Level

Parameters

queue-id: ID of the queue, in the range of 0 to 7.

weight schedule-value: Specifies the scheduling weight of a queue. The range for the scheduling weight depends on the LPU type of your S7500E series switch:

l For EA LPUs, the scheduling weight of each queue is 1, that is, all queues share the allocable bandwidth (allocable bandwidth = total bandwidth – the sum of the minimum guaranteed bandwidth for each queue).

l For non-EA LPUs, the scheduling weight ranges from 0 to 15, and each queue is allocated with part of the allocable bandwidth based on its scheduling weight.

Description

Use the qos wfq command to enable weighted fair queuing (WFQ) on a port or port group and configure a scheduling weight for the specified queue.

Use the undo qos wfq command to restore the default.

On a WFQ-enable port/port group, the scheduling weight of a queue is 1 by default.

Default Level

2: System Level

Parameters

queue-id: ID of the queue, in the range of 0 to 7.

group-id: It can only be 1.

weight schedule-value: Specifies the scheduling weight of a queue, rang from 1 to 15.

sp: Configures SP queuing.

Description

Use the qos wrr command to configure Weighted Round Robin (WRR) queue scheduling algorithm or the SP + WRR queue scheduling algorithm on a port or port group.

Use the undo qos wrr command to restore the default queue-scheduling algorithm on the port.

By default, the switch adopts the SP queue-scheduling algorithm.

As required, you can configure part of the queues on the port to adopt the SP queue-scheduling algorithm and parts of queues to adopt the WRR queue-scheduling algorithm. Through adding the queues on a port to the SP scheduling group and WRR scheduling group (namely, group 1), the SP + WRR queue scheduling is implemented. During the queue scheduling process, the queues in the SP scheduling group is scheduled preferentially. When no packet is to be sent in the queues in the SP scheduling group, the queues in the WRR scheduling group are scheduled. The queues in the SP scheduling group are scheduled according to the strict priority of each queue, while the queues in the WRR queue scheduling group are scheduled according the weight value of each queue.

Related commands: display qos wrr interface.

Examples

# Configure SP+WRR queue scheduling algorithm on GigabitEthernet 2/0/1 as follows: assign queue 0, queue 1, queue 2, and queue 3 to the SP scheduling group; and assign queue 4, queue 5, queue 5, and queue 7 to WRR scheduling group, with the weight 2, 4, 6, and 8.

queue-id: ID of the queue, in the range of 0 to 7.

drop-level drop-level: Specifies a drop level, in the range of 0 to 2. If this argument is not specified, the subsequent configuration takes effect on the packets in the queue regardless of the drop level.

low-limit low-limit: Specifies a lower threshold. When the queue length exceeds the lower threshold, WRED begins to drop packets. The low-limit argument ranges from 0 to 100 and defaults to 10.

discard-probability discard-prob: Specifies the discard-prob argument, which ranges from 0 to 90 and defaults to 10. Each drop level is configured with an independent drop probability. The meaning of discard-probability discard-prob depends on the type of the LPU where the WRED table-applied port resides, as shown in Table 4-2.

Table 4-2 Description on discard-probability discard-prob

LPU type	Description on discard-probability discard-prob
EA	In a coordinate graph with the queue length percentage as the abscissa and drop probability as the ordinate, discard-prob specifies the degree of the included angle between the abscissa and the straight line starting at (low-limit, 0) and ending at (100%, max-drop-probability). The degree of the included angel ranges from 0 to 90. l When the queue length is fixed, the bigger the argument, the bigger the drop-probability. l When the argument is fixed, the bigger the queue length, the bigger the drop-probability.
SC	Reciprocal of the drop probability. The argument corresponds to the drop probability as follows: l 0 corresponds to 100% l 1 through 8 corresponds to 1/8 l 9 through 16 corresponds to 1/16 l 17 through 32 corresponds to 1/32 l 33 through 64 corresponds to 1/64 l 65 through 90 corresponds to 1/128

LPU type

Description on discard-probability discard-prob

In a coordinate graph with the queue length percentage as the abscissa and drop probability as the ordinate, discard-prob specifies the degree of the included angle between the abscissa and the straight line starting at (low-limit, 0) and ending at (100%, max-drop-probability). The degree of the included angel ranges from 0 to 90.

l When the queue length is fixed, the bigger the argument, the bigger the drop-probability.

l When the argument is fixed, the bigger the queue length, the bigger the drop-probability.

Reciprocal of the drop probability. The argument corresponds to the drop probability as follows:

l 0 corresponds to 100%

l 1 through 8 corresponds to 1/8

l 9 through 16 corresponds to 1/16

l 17 through 32 corresponds to 1/32

l 33 through 64 corresponds to 1/64

l 65 through 90 corresponds to 1/128

Description

Use the queue command to configure the drop-related parameters for a specified queue in the WRED table.

Use the undo queue command to restore the default.

By default, the lower threshold is 10 and the discard-prob argument is 10 for all the drop levels in the WRED table.

Related commands: qos wred queue table.

Examples

# Modify drop parameters for queue 1 in the WRED table queue-table1: set the lower threshold to 10 and the degree of the included angle between the drop probability and queue length percentage to 30 for packets with drop level 1 in queue 1 (assuming the WRED table queue-table1 is applied to a port on an EA LPU).
