acl-rule: Applied ACL rules, for the ACL combinations of service modules other
than A type, refer to Table 560.
n
■ Only non-type-A I/O Modules support the traffic mirroring configuration.
■ You can configure only one reflector port of a remote source mirroring group
or one destination port of a local mirroring group on each centralized I/O
Module. As for the distributed system, you can configure only one reflector
port of a remote source mirroring group or one destination port of a local
mirroring group for the whole system. Only one mirroring destination I/O
Module can be configured for the centralized or distributed system, and can be
referenced by only one local mirroring group.
■ If you want to mirror the tagged packets, you need to configure VLAN VPN on
the reflector port.
■ For the reflector port can not forward traffic as a normal port does, you are
recommended to configure the port that is not in use to be the reflector port
and not to perform other configurations on this port.
Configuring the intermediate switch
Configuring an intermediate switch is the same as configuring remote port
mirroring on the intermediate switch. Refer to “Configuring remote port mirroring
on the intermediate switch” on page 692 for details.
Configuring the destination switch
Configuring a destination switch is the same as configuring remote port mirroring
on the destination switch. Refer to “Configuring remote port mirroring on the
destination switch” on page 692."
Configuration example
1 Network requirements:
■ Switch A is connected to the data detect device through GigabitEthernet 2/0/2.
■ GigabitEthernet 2/0/1, the relay port of Switch A, is connected to
GigabitEthernet 2/0/1, the relay port of Switch B.
■ GigabitEthernet 2/0/2, the relay port of Switch B, is connected to
GigabitEthernet 2/0/1, the relay port of Switch C.
■ GigabitEthernet 2/0/2, the port of Switch C, is connected to the 10.1.1.1/24
network segment.
