interval: Specifies the interval at which log entries are generated and output. It must be a multiple of 5, in the range of 0 to 1440 minutes. To disable the logging, set the value to 0.

Usage guidelines

The logging feature is available for IPv4 or IPv6 ACL rules that have the logging keyword.

You can configure the ACL module to generate log entries for packet filtering and output them to the information center at the output interval. The log entry records the number of matching packets and the matched ACL rules. When the first packet of a flow matches an ACL rule, the output interval starts, and the device immediately outputs a log entry for this packet. When the output interval ends, the device outputs a log entry for subsequent matching packets of the flow.

For more information about the information center, see Network Management and Monitoring Configuration Guide.

Examples

# Configure the device to generate and output packet filtering log entries every 10 minutes.

Parameters

interval: Specifies the interval at which SNMP notifications are generated and output. It must be a multiple of 5, in the range of 0 to 1440 minutes. To disable SNMP notifications, set the value to 0.

Usage guidelines

The SNMP notifications feature is available for IPv4 or IPv6 ACL rules that have the logging keyword.

You can configure the ACL module to generate SNMP notifications for packet filtering and output them to the SNMP module at the output interval. The notification records the number of matching packets and the matched ACL rules. When the first packet of a flow matches an ACL rule, the output interval starts, and the device immediately outputs a notification for this packet. When the output interval ends, the device outputs a notification for subsequent matching packets of the flow.

Use packet-filter to apply an ACL to an interface to filter packets.

Use undo packet-filter to remove an ACL from an interface.

Syntax

packet-filter [ ipv6 | mac | user-defined ] { acl-number | name acl-name } { inbound | outbound } [ hardware-count ] [ share-mode ]

undo packet-filter [ ipv6 | mac | user-defined ] { acl-number | name acl-name } { inbound | outbound }

Default

No ACL is applied to an interface to filter packets.

Parameters

ipv6: Specifies the IPv6 ACL type.

mac: Specifies the Layer 2 ACL type.

user-defined: Specifies the user-defined ACL type.

acl-number: Specifies an ACL by its number. The following are available value ranges:

· 2000 to 2999 for basic ACLs.

· 3000 to 3999 for advanced ACLs.

· 4000 to 4999 for Layer 2 ACLs.

name acl-name: Specifies an ACL by its name. The acl-name argument is a case-insensitive string of 1 to 63 characters.

inbound: Filters incoming packets.

outbound: Filters outgoing packets.

hardware-count: Enables counting ACL rule matches performed in hardware. If you do not specify this keyword, rule matches for the ACL are not counted in hardware.

share-mode: Applies the ACL in sharing mode to a Layer 2 or Layer 3 Ethernet interface. In this mode, all interfaces on the same device with the same ACL applied in one direction share one QoS and ACL resource.

Usage guidelines

To specify the IPv4 ACL type, do not specify the ipv6 keyword.

The hardware-count keyword in this command enables match counting in hardware for all rules in an ACL, and the counting keyword in the rule command enables match counting specific to rules.

On the S9855 switch series, the following interfaces do not support applying ACLs for packet filtering in the outbound direction:

· Layer 2 aggregate interfaces.

· Layer 3 aggregate interfaces.

· Layer 3 aggregate subinterfaces.

If a Layer 3 aggregate interface has subinterfaces, its member ports do not support applying ACLs for packet filtering in the outbound direction.

To disable ACL rule match counting in hardware when resources are insufficient, you must execute the undo packet-filter command and then re-execute the packet-filter command without specifying the hardware-count keyword.

To disable ACL rule match counting in hardware when resources are sufficient, you can directly re-execute the packet-filter command without specifying the hardware-count keyword.

You can apply a maximum of three ACLs to the inbound direction of an interface: one IPv4 or one IPv6 ACL, one Layer 2 ACL, and one user-defined ACL. You can apply a maximum of three ACLs to the outbound direction of an interface: one IPv4 or one IPv6 ACL and one Layer 2 ACL.

If you specify the share-mode keyword when applying an ACL to an interface, follow these restrictions and guidelines:

· You can apply multiple ACLs to one direction of an interface. However, you can apply only one ACL with the share-mode keyword specified to one direction of an interface.

· In the same direction of the interface, you cannot apply a QoS policy with the share-mode keyword. For more information about applying a QoS policy to an interface, see QoS commands in ACL and QoS Command Reference.

· You cannot change the sharing mode dynamically after an ACL is applied to an interface. To change the sharing mode for an applied ACL, you must remove the ACL from the interface, and then reapply the ACL with or without the share-mode keyword specified.

Examples

# Apply IPv4 basic ACL 2001 to filter incoming traffic on HundredGigE 1/0/1, and enable counting ACL rule matches performed in hardware.

<Sysname> system-view

[Sysname] interface hundredgige 1/0/1

packet-filter continuous enable

Use packet-filter continuous enable to enable the continuous mode for packet filtering.

Use undo packet-filter continuous enable to restore the default.

Syntax

packet-filter continuous enable

undo packet-filter continuous enable

Default

The continuous mode is disabled for packet filtering.

Views

System view

Predefined user roles

network-admin

Usage guidelines

The continuous mode takes effect only on packet filtering configured in system view and interface view. When you modify, delete, or add a rule in the ACL of a global or interface-based packet filter, the packet filter will be invalid for a short time. Enabling the continuous mode ensures that the packet filter is in effect while you are dynamically configuring the ACL. However, it affects forwarding performance (for example, reduces packet match speed).

As a best practice, enable the continuous mode before configuring packet filtering.

If you enable the continuous mode before configuring packet filtering, the continuous mode takes effect immediately.

If you enable or disable the continuous mode after configuring packet filtering, you must reboot the device for the continuous mode configuration to take effect.

Examples

# Enable the continuous mode for packet filtering.

<Sysname> system-view

[Sysname] packet-filter continuous enable

Enable the continuous mode for packet filter? [Y/N]:y

For the continuous mode to take effect, save the configuration, and then reboot the device.

packet-filter default deny

Use packet-filter default deny to set the packet filtering default action to deny. The packet filter denies packets that do not match any ACL rule.

Use undo packet-filter default deny to restore the default.

Syntax

packet-filter default deny

undo packet-filter default deny

Default

The packet filtering default action is permit. The packet filter permits packets that do not match any ACL rule.

Views

Predefined user roles

Usage guidelines

The packet filter applies the default action to all ACL applications for packet filtering. The default action appears in the display command output for packet filtering.

# Set the packet filter default action to deny.

[Sysname] packet-filter default deny

Usage guidelines

To specify the IPv4 ACL type, do not specify the ipv6 keyword.

The hardware-count keyword in this command enables match counting in hardware for all rules in an ACL, and the counting keyword in the rule command enables match counting specific to rules.

To disable the extended mode or ACL rule match counting in hardware when resources are insufficient, you must execute the undo packet-filter command and then re-execute the packet-filter command without specifying the hardware-count keyword.

To disable the extended mode or ACL rule match counting in hardware when resources are sufficient, you can directly re-execute the packet-filter command without specifying the hardware-count keyword.
