Parameter
inbound: Limits the rate of inbound packets.
outbound: Limits the rate of outbound packets.
target-rate: Total rate (in Kbps) to limit both the inbound and outbound packets on the
port, with the granularity of rate limit being 64 Kbps. If the number you input is in the
range of N*64 to (N+1)*64 (N is a natural number), the switch will set the value to
(N+1)*64 Kbps automatically. The target rate range for fast Ethernet ports and Gigabit
Ethernet ports respectively is:
z Fast Ethernet port: 64 to 99,968
z Gigabit Ethernet port: 64 to 1,000,000

Parameter
priority-level: Priority level of the port, ranging from 0 to 7.
Description
Use the priority command to configure the priority of Ethernet port.
Use the undo priority command to restore the default port priority.
By default, the switch uses the port priority instead of the 802.1p priority carried by a
packet.
After this command is configured, the switch will replace the packet 802.1p priority with
the priority of the receiving port, according to which the packet will be put into the
corresponding egress queue.

# Set the priority of Ethernet1/0/1 port to 6.

priority.
By default, the system replaces the priority carried by a packet with the port priority.

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.

inclusive for a Gigabit Ethernet port.
exceed action: Optional. The action is taken when the traffic exceeds the threshold.
The action can be:

Use the traffic-limit command to activate ACL-based traffic identification, impose
traffic limit, and take different actions on packets within/exceeding the traffic limit.
Use the undo traffic-limit command to remove traffic limit.
The granularity of traffic limit is 64 Kbps.

from 0 to 7. You can also enter the keywords list in
Table 1-7. from-ipprec means to set
802.1p priority of the packet to be the same as the IP precedence.

local-precedence pre-value: Sets local precedence. The pre-value argument ranges

Description
Use the traffic-priority command to apply ACLs in traffic classification and remark
priority for the traffic matching the ACLs. This command is effective only for the ACL
rules whose actions are permit.
Use the undo traffic-priority command to remove the function of remarking priority for
the specified traffic.
Note:
The CoS precedence and the local-precedence cannot be applied simultaneously on
the switch.
Related command: display qos-interface traffic-priority.
Example
# Remark the 802.1p priority of the packets that are received on Ethernet1/0/1 and
match the permit rule in ACL 4000 as 1.

View
Ethernet port view
Parameter
inbound: Performs traffic redirecting on the packets received by the interface.
outbound: Performs traffic redirecting on the packets sent by the interface.
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.
cpu: Redirects the traffic to the CPU.
interface interface-type interface-number: Redirects the packets to the specified
Ethernet port. The interface-type argument refers to the port type.
Description
Use the traffic-redirect command to activate the ACL to identify and redirect the traffic
(whose action is permit).
Use the undo traffic-redirect command to cancel the redirection.
Related command: display qos-interface traffic-redirect.
Note:
z After the packets are redirected to CPU, they cannot be forwarded normally.
z If the traffic is redirected to a Combo port in down state, the system automatically
redirects the traffic to the port corresponding to the Combo port in up state.
Example
# Redirect the packets that are received on Ethernet1/0/1 and match the permit rule in
ACL 2000 to Ethernet1/0/7.
