1.1.13 inboundcar

Syntax

inboundcar { enable | disable }

View

System view

Parameters

enable: Enables the inbound CAR feature.

disable: Disables the inbound CAR feature.

Description

Use the inboundcar enable command to enable the inbound CAR feature.

Use the inboundcar disable command to disable the inbound CAR feature.

By default, the inbound CAR feature is disabled.

& Note:

This command is only applicable to A-type LPUs and can take effect only after you restart the switch.

When the inbound CAR feature is enabled, the same ACL rule applied to different ports is treated as different rules, thus seizing multiple entries. If you enable the CAR feature for the traffic matching the same rule on multiple ports, the switch provides guaranteed bandwidth to the traffic matching the CAR rule on each port.

When the inbound CAR feature is disabled, the same ACL rule applied to different ports is treated as the same one, thus seizing one entry only. If you enable the CAR feature for the traffic matching the same rule on multiple ports, the switch provides guaranteed bandwidth to the traffic matching the CAR rule on these ports.

For example, if you want to set the CAR bandwidth of 2 M for the traffic matching ACL rule 0 on the switch, use the traffic-limit command to enable the CAR feature on two ports.

l If the inbound CAR feature is enabled, the two ports provides guaranteed bandwidth of 2 M for the traffic matching ACL rule 0 on each port.

l If the inbound CAR feature is disabled, the two ports provide the total guaranteed bandwidth of 2M for the traffic matching ACL rule 0 on the two ports.

View

QoS view

Parameters

kbps: Specifies the limit rate to be measured (in kbps).

target-rate: Total limit rate of all the packets sent by the port. If the kbps keyword is specified, the rate is measured in kbps, in the range of 64 to 1,024,000 with the granularity being 64. 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. If the kbps keyword is not specified, the rate is in the range of 1 to 1,000 in mbps.

Description

Use the line-rate command to limit the rate of the packets on the port.

Use the undo line-rate command to remove the rate limit configuration on the port.

& Note:

Only type-A LPUs support the rate limit configuration.

Parameters

priority-level: Priority value of the port, ranging from 0 to 7.

Description

Use the priority command to configure the priority of the Ethernet port.

Use the undo priority command to restore the default priority of the Ethernet port.

By default, the priority of a port is 0.

If the switch receives a VLAN-tagged frame, the switch will tag the frame with the default VLAN tag of the port receiving the frame. In this case the switch assigns the port priority of the port receiving the frame to the 802.1p priority of the VLAN tag in the frame.

The switch does not perform the operation above if it receives a VLAN-tagged frame.

1.1.16 priority trust

Syntax

priority-trust { dscp | ip-precedence | cos | local-precedence }

View

System view

Parameters

dscp: Puts a packet into the corresponding output queue on a port according to the DSCP precedence of the packet.

ip-precedence: Puts a packet into the corresponding output queue on a port according to the IP precedence of the packet.

cos: Puts a packet into the corresponding output queue on a port according to the CoS precedence of the packet.

local-precedence: Puts a packet into the corresponding output queue on a port according to the local precedence of the packet.

Description

Use the priority trust command to specify the priority type according to which the switch puts a packet into the output queue on a port.

By default, the switch puts a packet into the output queue on a port according to the local precedence of the packet.

A port supports eight output queues with different precedence levels. The packets in an output queue with a higher precedence will be delivered preferentially. The switch puts a packet into an output queue on a port according to the precedence of the packet.

l DSCP precedence ranges from 0 to 63. The packets with precedence value from 0 to 7 are put into queue 0, and those with precedence value from 8 to 15 are put into queue 1, and so on.

l IP precedence ranges from 0 to 7, the packets with precedence value 0 are put into queue 0, and those with precedence value 1 are put into queue 1, and so on.

l CoS precedence ranges from 0 to 7, the packets with precedence value 0 are put into queue 2, the packets with precedence value 1 are put into queue 0, and the packets with precedence value 2 are put into queue 1. As for the left precedence values, the queue number is equal to the precedence value. For example, the packets whose precedence value is 3 are put into queue 3.

l Local precedence ranges from 0 to 7. The packets with precedence value 0 are put into queue 0, and so on.

& Note:

For LPUs that are not of A-type, if you specify the trusted priority for adding packets to output queues by using the priority-trust dscp or priority-trust ip-precedence command, the switch will convert the DSCP precedence or IP precedence of the received packets to the corresponding CoS precedence according to the DSCP-CoS precedence mapping table or IP-CoS precedence mapping table and then add the packets to the corresponding queues by CoS priority. In this case, the precedence is converted as follows.

l DSCP precedence 0 through 7 are mapped to CoS precedence 2; 8 through 15 to CoS precedence 0; 16 through 23 to CoS precedence 1; 24 through 31 to CoS precedence 3; 32 through 39 to CoS precedence 4; 40 through 47 to CoS precedence 5, 48 through 55 to CoS precedence 6; 56 through 63 to CoS precedence 7.

l IP precedence 0 is mapped to CoS precedence 2; IP precedence 1 to CoS precedence 0; IP precedence 2 to CoS precedence 1; IP precedence 3 to CoS precedence 3. The values of other IP precedence values are the same as those of the corresponding CoS precedence.

You can choose the corresponding packet precedence as the basis for putting a packet into an output queue on a port as required.

# Configure the switch to put a packet into an output queue according to the DSCP precedence of the packet.

This command is applicable to ACLs used for filtering and classifying the traffic processed by software.

ACLs are referenced by software in the following cases:

l Referenced by routing policies

l Referenced when login users are controlled

In these cases, the ACL number is in the range of 2,000 to 3,999.

Refer to the ACL module in this manual for the introduction to the reset acl counter command.

reset traffic-statistic

Clear the traffic statistics.

This command is applicable to ACLs applied to the hardware of the switch for filtering and classifying traffic during data forwarding. Generally, this command is used to clear the statistics information obtained through the traffic-statistic command.

Syntax

traffic-bandwidth outbound acl-rule [ system-index ] min-guaranteed-bandwidth max-guaranteed-bandwidth weight

undo traffic-bandwidth outbound acl-rule

View

QoS view

Parameters

outbound: Guarantees the bandwidth for the packets sent by 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 1-4.

system-index: Specifies an interior index value which is used when an ACL rule is applied to the port. The index value ranges from 0 to 4294967295. This keyword is only available when the ACL rule number is specified in the command. After the specified ACL takes effect, there are three scenarios when you input the index value:

l If you do not input an index value or the index value you input is 0, the system will automatically assign an index whose value is greater than 0;

l If the input index value is not 0 and does not conflict with the interior index used by the system, the system will adopt the index value input by you;

l If the input index value is not 0 but conflicts with the interior index used by the system, the system will reassign an index value.

When the specified ACL rule is not effective, the system will adopt the index value input by you.

min-guaranteed-bandwidth: Minimum guaranteed bandwidth in kbps, in the range of 0 to 8,388,608. It must be a multiple of 64.

max-guaranteed-bandwidth: Maximum guaranteed bandwidth in kbps, in the range of 0 to 8,388,608. It must be the multiple(s) of 64.

weight: Bandwidth weight in the range of 1 to 100, in percentage. It is used in the situations when bandwidth guarantees are enabled for multiple flows respectively on the current port. For example, bandwidth guarantees are enabled for two flows on a port with 10 M of bandwidth. The minimum guaranteed bandwidth for each flow is 2 M, the maximum guaranteed bandwidth is 8 M, and the bandwidth weights are 40% and 80% respectively. After the port guarantees the minimum bandwidth for both flows (that is, 4 M), the remaining bandwidth (6M) cannot support the maximum bandwidth of both flows (16M). If the bandwidth occupied by the two flows exceeds the minimum guaranteed bandwidth, then the remaining bandwidth (6 M) will be allocated to each flow according to the bandwidth weights (40% : 80%).

& Note:

Assume there are N flows on a port, the bandwidth of the port is Bp, the minimum guaranteed bandwidth of the ith flow is Bimin, the maximum guaranteed bandwidth of the ith flow is Bimax, and the weight is Wi. If the bandwidth occupied by all the flows is greater than their minimum guaranteed bandwidth, and the sum of maximum guaranteed bandwidth is greater than port bandwidth Bp, the bandwidth allocated to the ith flow is Bi= Bimin+(Bp-)*Wi/.

Description

Use the traffic-bandwidth command to activate the ACL for traffic identifying and provide guaranteed bandwidth for the corresponding traffic. This command is applicable to only the permit rules in ACLs).

Use the undo traffic-bandwidth command to remove this feature.

This configuration provides the minimum guaranteed bandwidth and maximum available bandwidth for the specific traffic. Note that the maximum available bandwidth must be no smaller than the minimum guaranteed bandwidth.

Related command: display qos-interface traffic-bandwidth.

& Note:

l Only type-A LPUs support this command.

l Only the permit rule can be referenced in this command and applied to hardware.

Examples

# Guarantee the bandwidth of the packets that match the permit rule in ACL 2000: The minimum guaranteed bandwidth is 64 k, the maximum available bandwidth is 128 k, and bandwidth weight is 50.
