Matches an ACL. The acl-number argument ranges from 2000 to 5999 for an IPv4 ACL, and 2000 to 3999 or 10000 to 42767 for an IPv6 ACL. The acl-name argument is a case-insensitive string of 1 to 32 characters, which must start with an English letter from a to z or A to Z, and to avoid confusion, cannot be all. |
|

|
service-dot1p 8021p-list |
Matches the 802.1p priority of the service provider network. The 8021p-list argument is a list of up to eight 802.1p priority values. An 802.1p priority ranges from 0 to 7. |
|
ip-precedence ip-precedence-list |
Matches IP precedence. The ip-precedence-list argument is a list of up to eight IP precedence values. An IP precedence ranges from 0 to 7. |
|
protocol protocol-name |
Matches a protocol. The protocol-name argument can be IP or IPv6 |
|
source-mac mac-address |

|
service-vlan-id { vlan-id-list | vlan-id1 to vlan-id2 } |
Matches the VLAN IDs of ISP networks. The vlan-id-list is a list of up to eight VLAN IDs. The vlan-id1 to vlan-id2 specifies a VLAN ID range, where the vlan-id1 must be smaller than the vlan-id2. A VLAN ID ranges from 1 to 4094. |
|
|
NOTE: If a class that uses the AND operator has multiple if-match acl, if-match acl ipv6, if-match customer-vlan-id or if-match service-vlan-id clauses, a packet that matches any of the clauses matches the class. |
|
|
NOTE: To successfully apply a traffic class that uses the AND operator, define only one if-match clause for any of the following match criteria and input only one value for any of the following list arguments, for example, the 8021p-list argument: · customer-dot1p 8021p-list · destination-mac mac-address · dscp dscp-list · ip-precedence ip-precedence-list · service-dot1p 8021p-list · source-mac mac-address |
|
|
NOTE: In a class that uses the operator AND, follow these guidelines when configuring match criteria: · You cannot configure if-match dscp and if-match ip-precedence at the same time. · If the class if configured with if-match dscp or if-match ip-precedence, you can configure if-match protocol ip but not if-match protocol ipv6. |
Description
Use the if-match command to define a match criterion.
Use the undo if-match command to delete a match criterion.
Use the if-match not command to define a criterion for matching traffic not conforming to the specified criterion.
Use the undo if-match not command to delete a criterion for matching traffic not conforming to the specified criterion.
When defining match criteria, use the usage guidelines described in these subsections:
Defining an ACL-based match criterion
Defining a criterion to match a destination MAC address
Defining a criterion to match a source MAC address
Defining a criterion to match DSCP values
Defining a criterion to match 802.1p priority in customer or service provider VLAN tags
Defining a criterion to match IP precedence values
Defining a criterion to match customer network VLAN IDs or service provider network VLAN IDs
Defining an ACL-based match criterion
If the ACL referenced in the if-match command does not exist, the class cannot be applied to hardware.
For a class, you can reference an ACL twice by its name and number respectively with the if-match command.
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 criterion to match a source MAC address 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 rule (the sequence may be different).
Defining a criterion to match 802.1p priority in customer or service provider 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 customer network VLAN IDs or service provider 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).

Parameters
inbound: Inbound direction.
policy-name: Specifies a policy name, a string of 1 to 31 characters.
Description
Use the qos apply policy command to apply a QoS policy.
Use the undo qos apply policy command to remove the QoS policy.
In interface view, the setting takes effect on the current interface only. In port group view, the setting takes effect on all ports in the port group.
Examples
# Apply policy USER1 in the inbound direction of GigabitEthernet 1/0/1.

Default level
2: System level
Parameters
inbound: Applies the QoS policy to the traffic sent by the online users.
policy-name: Policy name, a string of 1 to 31 characters.
Description
Use the qos apply policy command to apply a QoS policy to a user profile.
Use the undo qos apply policy command to remove the QoS policy.
If a user profile is activated, the QoS policy, except the ACLs referenced in the QoS policy, applied to it cannot be configured or removed. When the users of the user profile are online, the referenced ACLs cannot be modified either.
The QoS policy applied to a user profile takes effect when the user-profile is activated and the users are online.
Only the remark and filter actions are supported in the QoS policies applied in user profile view.
A null policy cannot be applied in user profile view.

Parameters
None
Description
Use the burst-mode enable command to enable the burst function.
Use the undo burst-mode enable command to disable the burst function.
By default, the burst function is disabled.
The burst function improves packet buffering and forwarding performance in the following scenarios:
· Dense broadcast or multicast traffic and massive burst traffic are present.
· High-speed traffic is forwarded over a low-speed link or traffic received from multiple interfaces at the same speed is forwarded through an interface at the same speed.
By enabling the burst function on your device, you can improve the processing performance of the device operating in these scenarios and reduce packet loss rate.
Examples
# Enable the burst function.
<Sysname> system-view
[Sysname] burst-mode enable
