Usage guidelines

Defining an ACL-based match criterion

If the ACL used in the if-match command does not exist, the class cannot be applied to hardware.

For a class, you can use an ACL twice by its name and number with the if-match command, respectively.

Defining a criterion to match a destination MAC address

You can configure multiple destination MAC address match criteria for a class.

A destination MAC address match criterion is significant only to Ethernet interfaces.

Defining a criterion to match a source MAC address

You can configure multiple source MAC address match criteria for a class.

A source MAC address match criterion is significant only to Ethernet interfaces.

Defining a criterion to match DSCP values

·          You can configure multiple DSCP match criteria for a class. All defined DSCP values are automatically sorted in ascending order.

·          You can configure up to eight DSCP values in one command line. If multiple identical DSCP values are specified, the system considers them as one. If a packet matches one of the defined DSCP values, it matches the if-match clause.

·          To delete a criterion that matches DSCP values, the specified DSCP values must be identical with those defined in the criterion (the sequence may be different).

Defining a criterion to match 802.1p priority in customer network VLAN tags

·          You can configure multiple 802.1p priority match criteria for a class. All the defined 802.1p values are automatically arranged in ascending order.

·          You can configure up to eight 802.1p priority values in one command line. If the same 802.1p priority value is specified multiple times, the system considers them as one. If a packet matches one of the defined 802.1p priority values, it matches the if-match clause.

·          To delete a criterion that matches 802.1p priority values, the specified 802.1p priority values in the command must be identical with those defined in the criterion (the sequence may be different).

Defining a criterion to match IP precedence values

·          You can configure multiple IP precedence match criteria for a class. The defined IP precedence values are automatically arranged in ascending order.

·          You can configure up to eight IP precedence values in one command line. If the same IP precedence is specified multiple times, the system considers them as one. If a packet matches one of the defined IP precedence values, it matches the if-match clause.

·          To delete a criterion that matches IP precedence values, the specified IP precedence values in the command must be identical with those defined in the criterion (the sequence may be different).

Defining a criterion to match local precedence values

·          You can configure multiple local precedence match criteria for a class. The defined local precedence values are automatically arranged in ascending order.

·          You can configure up to eight local precedence values in one command line. If the same local precedence value is specified multiple times, the system considers them as one. If a packet matches one of the defined local precedence values, it matches the if-match clause.

·          To delete a criterion that matches local precedence values, the specified local precedence values must be identical with those defined in the match criterion (the sequence may be different).

Defining a criterion to match customer network VLAN IDs

·          You can configure multiple VLAN ID match criteria for a class. The defined VLAN IDs are automatically arranged in ascending order.

·          You can configure multiple VLAN IDs in one command line. If the same VLAN ID is specified multiple times, the system considers them as one. If a packet matches one of the defined VLAN IDs, it matches the if-match clause.

·          To delete a criterion that matches VLAN IDs, the specified VLAN IDs in the command must be identical with those defined in the criterion (the sequence may be different).

Views

Traffic behavior view

Default command level

2: System level

Parameters

cir committed-information-rate: Sets the committed information rate (CIR) in kbps, which specifies an average traffic rate.

cbs committed-burst-size: Sets the committed burst size (CBS) in bytes.

ebs excess-burst-size: Sets the excess burst size (EBS) in bytes. The default is 0.

pir peak-information-rate: Sets the peak information rate (PIR) in kbps.

green action: Sets the action to take on packets that conform to CIR. The default is pass.

red action: Sets the action to take on the packet that conforms to neither CIR nor PIR. The default is discard.

action: Sets the action to take on the packet:

·          discard: Drops the packet.

·          pass: Permits the packet to pass through.

·          remark-lp-pass new-local-precedence: Sets the local precedence value of the packet to new-local-precedence and permits the packet to pass through. The new-local-precedence argument ranges from 0 to 7.

Usage guidelines

A QoS policy that has a CAR action can be applied to the inbound or outbound direction of an interface.

If a QoS policy that has a CAR action and the qos car command are both configured on an interface, only the CAR action in the policy takes effect.

A traffic behavior can contain only one CAR action. If you configure the car command multiple times in the same traffic behavior, the last configuration takes effect.

Examples

# Configure a CAR action in traffic behavior database (set the CIR to 200 kbps, CBS to 50000 bytes, and EBS to 0, and permit the conforming packets to pass, and mark the excess packets with local precedence 0 and forward them.)

Parameters

priority-value: Specifies the port priority value in the range of 0 to 7.

Usage guidelines

If a WLAN-BSS interface is being used, you cannot modify its port priority. To do so, you must log off all online users to stop the service the interface is providing.

Examples

# Set the port priority of interface GigabitEthernet 1/0/1 to 2.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] qos priority 2

# Set the port priority of interface WLAN-BSS 1 to 2.

<Sysname> system-view

[Sysname] interface wlan-bss 1

[Sysname-WLAN-BSS1] qos priority 2

Port priority trust mode commands

Parameters

interface-type interface-number: Specifies an interface by its type and number.

|: Filters command output by specifying a regular expression. For more information about regular expressions, see Fundamentals Configuration Guide.

begin: Displays the first line that matches the specified regular expression and all lines that follow.

exclude: Displays all lines that do not match the specified regular expression.

include: Displays all lines that match the specified regular expression.

regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.

Usage guidelines

If no interface is specified, the command displays priority trust mode and port priority information for all interfaces.

Examples

# Display the priority trust mode and port priority settings of GigabitEthernet 1/0/1.

<Sysname> display qos trust interface gigabitethernet 1/0/1

Interface: GigabitEthernet1/0/1

Parameters

auto: Uses the priority in incoming packets for priority mapping. For Layer 2 packets, the 802.1p priority is used. For Layer 3 packets, the IP precedence is used.

dot11e: Uses the 802.11e priority in incoming packets for priority mapping. This keyword is available only on WLAN-BSS interfaces.

dot1p: Uses the 802.1p priority in incoming packets for priority mapping.

dscp: Uses the DSCP value in incoming packets for priority mapping.

Usage guidelines

If a WLAN-BSS interface is being used, you cannot modify its priority trust mode. To do so, you must log off all online users to stop the service the interface is providing.

Examples

# Set the trusted packet priority type to 802.1p priority on GigabitEthernet 1/0/1.
