Parameter
inbound: Mirrors inbound packets at the port.
ip-group { acl-number | acl-name }: Activates IP ACLs, including basic and
advanced ACLs. acl-number: Sequence number of ACL, ranging from 2000 to
3999. acl-name: Name of the ACL, which must be a character string starting with
an English letter (a-z or A-Z), and without any space in it.
rule rule: Specifies the subitem of an active ACL, ranging from 0 to 127; if not
specified, all subitems of ACL will be activated.
system-index index: Specifies the system index value of the rule which will be
indexed during operation. After delivering a rule, the system automatically assigns
a globally unique index value to the rule. When using the mirrored-to command
to deliver a rule, you can also specify a system index value for the rule, but this
value may change while the system is running. In general, you are not
recommended to specify this parameter manually.
cpu: Mirrors traffic to the CPU.
Description
Use the mirrored-to command to activate an ACL and mirror matching data
streams in VLAN to the CPU.
Use the undo mirrored-to command to remove traffic mirroring setting.
This configuration is only applicable to the packets which match the permit rules
in the ACL.
Example
# Mirror to the CPU the packets which are received by a port in VLAN2 and match
the permit rules in the ACL 2000.
