1.5.5 Collecting Statistics on the Traffic That Matches an ACL Rule
Context
By configuring the traffic statistics action, the S3700 collects traffic statistics on packets
matching traffic classification rules.
Procedure
l
Issue 01 (2012-03-15)
NOTE
When the traffic-remark command and the traffic-filter (interface view) or traffic-filter
(system view) command are used simultaneously, and the same ACL rule is associated:
l If the deny action is configured in the ACL rule, the traffic-remark command does not
take effect.
l If the permit action is configured in the ACL rule, the traffic-remark command takes
effect.
A Layer 2 ACL and a Layer 3 ACL can be set in the traffic-remark 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 inbound interface of a switch, use
the following command:
traffic-remark inbound acl { l2-acl | name acl-name } [ rule rule-id ] acl { bas-acl | adv-
acl | name acl-name } [ rule rule-id ] { 8021p 8021p-value | destination-mac mac-address |
dscp { dscp-name | dscp-value } | local-precedence local-precedence-value | ip-precedence
ip-precedence-value | vlan-id vlan-id }
Configuring traffic statistics globally
1.
Run:
system-view
The system view is displayed.
2.
Run:
traffic-statistic [ vlan vlan-id ] 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
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-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 [ vlan vlan-id ] inbound acl { l2-acl | name acl-name } [ rule rule-id ] acl
{ bas-acl | adv-acl | name acl-name } [ rule rule-id ]
