1.5.3 Filtering the Traffic That Matches an ACL Rule
Context
By filtering the traffic that matches an ACL rule, the S3700 rejects or permits the packets that
match the ACL rule so that the traffic is controlled.

Configuring traffic filtering globally
1.
Run:
system-view
The system view is displayed.
2.
Run:
traffic-filter [ vlan vlan-id ] inbound acl { [ ipv6 ] { bas-acl | adv-
acl | name acl-name } | l2-acl | user-acl } [ rule rule-id ]
The incoming packets matching an ACL rule are filtered on an interface.
NOTE
If the value of vlan vlan-id is specified, it indicates that VLAN-based traffic filtering is
configured and the traffic matching an ACL rule is filtered on all interfaces on the VLAN.
If the value of vlan vlan-id is not specified, the statistics on the traffic matching an ACL rule
are collected on all interfaces of the device.
A Layer 2 ACL and a Layer 3 ACL can be set in the traffic-filter command simultaneously.
The Layer 3 ACL and its rules can be configured only after the Layer 2 ACL and its rules are
configured. The Layer 2 ACL number ranges from 4000 to 4999 and the Layer 3 ACL number
ranges from 2000 to 2999 or 3000 to 3999.
To configure both Layer 2 ACLs and Layer 3 ACLs on a switch interface, use the following
command:
traffic-filter [ vlan vlan-id ] inbound acl { l2-acl | name acl-name } [ rule rule-id ] acl { bas-
acl | adv-acl | name acl-name } [ rule rule-id ]
Configuring traffic filtering on an interface
1.
Run:
system-view
The system view is displayed.
2.
Run:
interface interface-type interface-number
The interface view is displayed.
Or, run:
interface eth-trunk trunk-id
The Eth-Trunk interface view is displayed.
3.
Run:
traffic-filter inbound acl { [ ipv6 ] {bas-acl | adv-acl | name acl-name }
| l2-acl | user-acl } [ rule rule-id ]
The incoming packets matching an ACL rule are filtered on an interface.
