Table 1-5 Description on the parameters used in
ip-group acl-number
link-group acl-number
User-group acl-number
Rule-id
monitor-interface: Duplicates packets to the specified destination port (the monitor port).
cpu: Duplicates packets to the CPU.
Description
Use the mirrored-to command to configure traffic mirroring.
Use the undo mirrored-to command to cancel the configuration.
Traffic monitoring provides a finer mirroring granularity than port mirroring, which mirrors
all traffic passing through a port. For detailed information about port mirroring, refer to the
part talking about mirroring.
Note that:
If you mirror traffic to the CPU, you do not need to configure a monitor port.
If you mirror traffic to a port, you must configure a monitor port with the
mirroring-group monitor-port command or the monitor-port command. For
information about the two commands, refer to the part talking about mirroring.
Traffic mirroring and local port mirroring share the same monitor port.
Related commands: display qos-interface mirrored-to.
Examples
# Configure traffic mirroring on Ethernet 1/0/1, duplicating the inbound packets sourced
from IP address 1.1.1.1 to Ethernet 1/0/4.
