interface for the ease of packet analysis.
Procedure

Configuring traffic statistics 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-statistic inbound acl { [ ipv6 ] {bas-acl | adv-acl | name acl-
name } | l2-acl | user-acl } [ rule rule-id ]
The statistics on the incoming packets matching an ACL rule are collected on an
interface.
NOTE
A Layer 2 ACL and a Layer 3 ACL can be set in the traffic-statistic 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 an interface of a switch, use the
following command:
traffic-statistic inbound acl { l2-acl | name acl-name } [ rule rule-id ] acl { bas-acl | adv-
acl | name acl-name } [ rule rule-id ] [ by-bytes ]
Configure traffic mirroring globally.
1.
Run:
system-view
The system view is displayed.
2.
Run:
traffic-mirror [ vlan vlan-id ] inbound { acl { [ ipv6 ] { bas-acl | adv-
acl | name acl-name } | l2-acl | user-acl } } [ rule rule-id ] to observe-

The incoming packets matching an ACL rule are mirrored on an interface.
