1.5.7 Redirecting the Traffic That Matches an ACL Rule
Context
By configuring the redirection action, the S3700 redirects the packets matching traffic
classification rules to the CPU, the specified interface, or the specified next hop address.
Procedure
l
Issue 01 (2012-03-15)
NOTE
If the value of vlan vlan-id is specified, it indicates that VLAN-based traffic mirroring is
configured and traffic that matches an ACL rule is filtered on all interfaces on the VLAN.
If the value of vlan vlan-id is not specified, it indicates that the statistics on the traffic that
matches 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-mirror 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 and 3000 to 3999. To configure both Layer 2 ACLs and Layer 3
ACLs on an inbound interface of a switch, run the following command:
traffic-mirror [ vlan vlan-id ] inbound acl { l2-acl | name acl-name } [ rule rule-id ] acl
{ bas-acl | adv-acl | name acl-name } [ rule rule-id ] to observe-port o-index
Configure traffic mirroring on an interface.
1.
Run:
system-view
The system view is displayed.
2.
Run:
interface interface-type interface-number
or
interface eth-trunk trunk-id
The interface view or the Eth-Trunk interface view is displayed.
3.
Run:
traffic-mirror inbound { acl { [ ipv6 ] { bas-acl | adv-acl | name acl-
name } | l2-acl | user-acl } } [ rule rule-id ] to observe-port o-index
The incoming packets matching an ACL rule are mirrored on an interface.
NOTE
A Layer 2 ACL and a Layer 3 ACL can be set in the traffic-mirror 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 and 3000 to 3999. To configure both Layer 2 ACLs and Layer 3
ACLs on an inbound interface of a switch, run the following command:
traffic-mirror inbound acl { l2-acl | name acl-name } [ rule rule-id ] acl { bas-acl | adv-
acl | name acl-name } [ rule rule-id ] to observe-port o-index
