Description

Use the if-match command to define a match criterion.

Use the undo if-match command to delete the match criterion.

When defining match criteria, use the usage guidelines described in these subsections:

l          Define an ACL-based match criterion

l          Define a criterion to match a destination MAC address

l          Define a criterion to match a source MAC address

l          Define a criterion to match DSCP values

l          Define a criterion to match the 802.1p priority values of the customer network

l          Define a criterion to match the IP precedence values

l          Define a criterion to match customer network VLAN IDs

Define an ACL-based match criterion

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

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

Define a criterion to match a destination MAC address

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

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

Define a criterion to match a source MAC address

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

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

Define a criterion to match DSCP values

l          You can configure multiple DSCP match criteria for a class. All the defined DSCP values are automatically arranged in ascending order.

l          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.

l          To delete a criterion matching DSCP values, the specified DSCP values must be identical with those defined in the rule (the sequence may be different).

Define a criterion to match the 802.1p priority values of the customer network

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

l          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.

l          To delete a criterion matching 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).

l          The match criterion takes effect only on incoming traffic.

Define a criterion to match the IP precedence values

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

l          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.

l          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).

Define a criterion to match customer network VLAN IDs

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

l          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.

l          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).

l          The match criterion takes effect only on incoming traffic.

Related commands: traffic classifier.

Port Priority Configuration Commands

qos priority

Syntax

qos priority priority-value

undo qos priority

View

Interface view

Default Level

2: System level

Parameters

priority-value: Port priority value, which ranges from 0 to 7.

Description

Use the qos priority command to change the port priority of an interface.

Use the undo qos priority command to restore the default value.

By default, the port priority of an interface is 0.

If a WLAN-BSS interface is in use, you cannot modify the port priority of the WLAN-BSS interface. To do so, you must stop the service the interface provides (in other words, make the current users on the interface offline) and then modify the port priority.

Examples

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

<Sysname> system-view

[Sysname] interface ethernet 1/0/1

[Sysname-Ethernet1/0/1] qos priority 2

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

display qos trust interface

Syntax

Default Level

Parameters

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

Description

Use the display qos trust interface command to display the priority trust mode and port priority information of an interface.

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 information of Ethernet 1/0/1.

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

Interface: Ethernet1/0/1

 Port priority information

qos trust

Syntax

qos trust { dot11e | dot1p | dscp }

undo qos trust

View

Interface view

Default Level

2: System level

Parameters

dot11e: Uses the 802.11e priority in incoming packets for priority mapping. This keyword is applicable to only WLAN-ESS interfaces.

dot1p: Uses the 802.1p priority in incoming packets for priority mapping. This keyword is applicable to only Ethernet interfaces.

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

Description

Use the qos trust command to configure an interface to use a particular priority field carried in packets for priority mapping.

Use the undo qos trust command to restore the default.

By default, QoS is disabled.

When packets enter the AP, the AP assigns a series of parameters (including 802.11e priority, 802.1p priority, DSCP value, and local precedence value) to the packets as configured.

A local precedence value is locally significant and corresponds to an output queue.

If a WLAN-BSS interface is in use, you cannot modify the priority trust mode of the WLAN-BSS interface. To do so, stop the service the interface provides (in other words, make the current users on the interface offline) first.

Examples

# Configure Ethernet 1/0/1 to use the 802.1p priority in incoming packets for priority mapping.
