Parameter Description
user-group { acl-number | acl-name }
User-defined ACL
acl-number: ACL number of the
user-defined ACL, ranging from 5,000 to
5,999.
acl-name: ACL name, up to 32
characters long, beginning with an
English letter (a to z or A to Z) without
space and quotation mark, not case
sensitive.
rule-id Number of the ACL rule, ranging from 0 to
127. If this argument is not specified, all
rules in the specified ACL will be applied.
system-index: Specifies an interior index value which is used when an ACL rule is
applied to the port. The index value ranges from 0 to 4294,967,295. This keyword is
only available when the ACL rule number is specified in the command. After the
specified ACL takes effect, there are three scenarios when you input the index value:
z If you do not input an index value or the index value you input is 0, the system will
automatically assign an index whose value is greater than 0;
z If the input index value is not 0 and does not conflict with the interior index used by
the system, the system will adopt the index value input by you;
z If the input index value is not 0 but conflicts with the interior index used by the
system, the system will reassign an index value.
When the specified ACL rule is not effective, the system will adopt the index value input
by you.
Interface interface-type interface-number [ reflector ]: Mirrors traffic flows to specific
port. interface-type interface-number indicates an Ethernet port. With the reflector
keyword specified, the parameters represent a reflector port, together with
corresponding configuration to realize remote traffic mirroring; without the reflector
keyword, the parameters represent a destination port, used to realize the local traffic
mirroring.
mirroring-group group-id: Mirrors traffic flows to specific mirroring group.
Description
Use the mirrored-to command to start ACLs to identify traffics and perform traffic
mirroring for packets that match.
Use the undo mirrored-to command to remove traffic mirroring configuration.
This command only applies to the rules whose actions are permit in matching the
specified ACL, and only mirrors the received traffic flows. If you want to mirror traffic
flows to a specified port, the port must be a destination port or reflector port of a
mirroring group.
