Avaya switch port monitoring configuration

In the Avaya switch user manual, Port monitoring is called "Port image" Port Mirror ).
Run the following command to configure a port listener:
{Set | clear} Port Mirror
Set port listening: set port mirror Source-port Mirror-port Sampling {always | disable | periodic} [max-packets-sec <max-packets-sec-value>] [piggyback-port ]
Disable port listening: clear port mirror
In the command, mod-port-range specifies the port range; mod-port-spec specifies the specific port; piggyback-port specifies the port of the two-way image; sampling specifies the image cycle; max-packets-sec is only used when sampling is set to periodic. It specifies the maximum number of data entries per second for the listener.
