undo queue-scheduler

View

System view/Ethernet port view

Parameter

strict-priority: Indicates that the queue uses strict priority (SP) scheduling algorithm.

wfq: Indicates that the queue uses weighted fair queue (WFQ) scheduling.

queue0-width queue1-width queue2-width queue3-width queue4-width queue5-width queue6-width queue7-width: Minimum delivery bandwidth of each WFQ queue in Kbps. Its granularity is 64 Kbps. If the number you enter is in the range of N*64 to (N+1)*64 (N is a natural number), the switch sets the value to (N+1)*64 automatically. The value for fast Ethernet ports is in the range of 64 to 99,968, and the value for Gigabit Ethernet ports is in the range of 64 to 1,000,000. A value of 0 means the corresponding queue uses the SP scheduling.

wrr: Indicates that the queue uses weighted round robin (WRR) scheduling.

queue0-weight queue1-weight queue2-weight queue3-weight queue4-weight queue5-weight queue6-weight queue7-weight: Indicates that the queue uses the WRR scheduling. The value ranges from 0 to 15. A value of 0 means the corresponding queue uses the SP scheduling.

Description

Use the queue-scheduler command to configure the queue scheduling mode.

Use the undo queue-scheduler command to restore the default value.

The queue scheduling algorithm defined by executing the queue-scheduler command in system view takes effect on all the ports of the switch. The queue scheduling algorithm defined by executing the queue-scheduler command in Ethernet port view takes effect on the current port only. If the weight (or bandwidth value) of the WRR (or WFQ) queue scheduling algorithm defined globally cannot satisfy the requirement of a port, you can modify the weight (or bandwidth value) of the queue scheduling algorithm for this port in Ethernet port view of this port. On this port, the newly defined queue weight (or bandwidth value) will replace the globally defined one. You cannot use the display queue-scheduler command to display the queue weight (or bandwidth value) defined in Ethernet port view.

A port of the switch supports eight egress queues and you can configure a queue scheduling mode, which can be SP, WRR, or WFQ as needed to achieve the implementation of WRR+SP or WFQ+SP. For example, with WRR or WFQ, if you set the weight or the minimum bandwidth of one or more queues to 0, the SP applies to the queue(s) and WRR or WFQ apply to other queues.

By default, the WRR algorithm is selected for all outbound queues on a port, and their weight values are 1, 2, 3, 4, 5, 9, 13, and 15.

Related command: display queue-scheduler.

Example

# Set WRR as the queue scheduling mode, and set the weight value of each queue to 1, 2, 3, 4, 5, 6, 7, and 8, respectively.

Parameter

inbound: Filters the inbound packets on the port.

outbound: Filters the outbound packets on the port.

acl-rule: Applied ACL rules which can be the combination of various ACL rules. For the ways of combining ACLs and the description on related parameters, refer to Table 1-5 and Table 1-6.

Description

Use the packet-filter command to add packet filtering action to the QoS profile.

Use the undo packet-filter command to remove packet filtering action from the QoS profile.

Example

# Add the packet filtering action to the QoS profile named a123. The action is to filter the inbound packets matching ACL 4000.

System View: return to User View with Ctrl+Z.

2.1.4 qos-profile

Syntax

qos-profile profile-name

undo qos-profile profile-name

View

System view

Parameter

Description

Use the qos-profile command to create a QoS profile and enter the corresponding view. For an existing QoS profile, use this command to directly enter the corresponding view.

Use the undo qos-profile command to delete a QoS profile.

You cannot delete a QoS profile that has been applied to the port.

Example

# Create a QoS profile named a123.

<H3C> system-view

System View: return to User View with Ctrl+Z.

2.1.5 qos-profile port-based

Syntax

qos-profile port-based

undo qos-profile port-based

View

Ethernet port view

Parameter

None

Description

Use the qos-profile port-based command to configure the application of the QoS profile on the port to be port-based.

Use the undo qos-profile port-based command to restore the default application mode.

By default, a QoS profile is applied on a port in user-based mode.

l If the 802.1x authentication is MAC-based, you must configure the QoS profile application mode to be user-based.

l If the 802.1x authentication is port-based, you must configure the QoS profile application mode to be port-based.

After you configure the QoS profiles and the user passes the authentication, the switch delivers the right profile dynamically to the port through which the user is connected. The QoS profile can be delivered to the port in one of the following two modes:

l User-based mode: If the source station information (source MAC address, source IP address, or source MAC address + source IP address) has been defined in the ACL that is applied in the traffic actions, the switch cannot deliver the QoS profile dynamically; if no source station information is available, the switch generates a new ACL by adding the source MAC address and source IP address of the user into the existing ACL, and then applies all traffic actions in the QoS profile on the user port.

l Port-based mode: The switch delivers the traffic actions in the QoS profile directly to the user port. In this mode, all the users connected through one port should use the same QoS profile.

Example

# Configure the application mode of the QoS profile on Ethernet1/0/1 as the port-based mode.

<H3C> system-view

System View: return to User View with Ctrl+Z.

2.1.6 traffic-limit

Syntax

traffic-limit inbound acl-rule target-rate [ exceed exceed-action ]

undo traffic-limit inbound acl-rule

View

QoS profile view

Parameter

inbound: Imposes traffic limit on the inbound packets through the port.

acl-rule: Applied ACL rules which can be the combination of various ACL rules. For the ways of combining ACLs and the description on related parameters, refer to Table 1-5 and Table 1-6.

target-rate: Total traffic (in Kbps) to be set, with the granularity of traffic limit being 64Kbps. If the number user input ranges from N*64 to (N+1)*64, where N is a natural number, the switch automatically sets (N+1)*64 as the parameter value. The value of port rate ranges from 64 to 1,000,000.

exceed action: Specifies the action to be taken when the traffic threshold is exceeded (optional). Two actions are available:

l drop: Drops packets.

l remark-dscp value: Sets a new DSCP value.

Description

Use the traffic-limit command to add traffic policing action to the QoS profile.

Use the undo traffic-limit command to remove traffic policing action from the QoS profile.

You cannot remove traffic policing action from the specific QoS profile that has been applied to the port.

Example

# Add this traffic policing action to the QoS profile named a123: Limit traffic matching ACL 2000, set the target rate to 128 Kbps, and drop the packets that exceed this target rate.

<H3C> system-view

System View: return to User View with Ctrl+Z.

2.1.7 traffic-priority

Syntax

undo traffic-priority { inbound | outbound } acl-rule

View

QoS profile view

Parameter

inbound: Remarks the preference value for the inbound packets on the port.

outbound: Remarks the preference value for the outbound packets through the port.

acl-rule: Applied ACL rules which can be the combination of various ACL rules. For the ways of combining ACLs and the description on related parameters, refer to Table 1-5 and Table 1-6.

dscp dscp-value: Sets DSCP preference value, in the range 0 to 63. You can also enter keywords listed in Table 1-2.

ip-precedence { pre-value | from-cos }: Sets IP preference value. pre-value is in the range of 0 to 7. You can also enter keywords listed in Table 1-1. from-cos sets the IP preference value consistent with 802.1p preference value.

cos { pre-value | from-ipprec }: Sets 802.1p preference value. pre-value is in the range of 0 to 7. You can also enter keywords listed in Table 1-7. from-ipprec sets the 802.1p preference value consistent with the IP preference value.

local-precedence pre-value: Sets local preference value, in the range of 0 to 7.

Description

Use the traffic-priority command to enable the ACL and preference marking.

Use the undo traffic-priority command to remove the preference marking.

You cannot remove preference marking from a QoS profile that has been applied to the port.

& Note:

The CoS precedence and the local-precedence cannot be applied simultaneously on the switch.

Example

# Add preference marking to the QoS profile named a123. The action is to set the local preference of the inbound packets matching ACL 2000 to 0.

System View: return to User View with Ctrl+Z.
