interfaces will be displayed.

2.2.16 Display/ clear interface statistics information

Use show statistics interface [interface-num] command in any configuration mode to display

information of specified interface or all interfaces:

 Byte receiving

 Unicast packet receiving

 Non-unicast packet receiving

 Unicast packet sending

 Non-unicast packet sending

Use clear interface [interface-num | slot-num ] command in global configuration mode to clear

information of specified interface or all interfaces in specified slot or all interfaces. Use clear

2.3 Interface mirror

2.3.1 Brief introduction of interface mirror

System provides mirror based on interface, that is, copy packet in a or more specified interface

to monitor interface to analyze and monitor packet. For example, copy packet of Ethernet 0/2

to specified monitor interface Ethernet 0/3 so that test and keep record by protocols linked by

monitor interface Ethernet 0/3.

System also provides packet mirror for specified source/destination MAC address. For

example, mirror packet from Ethernet 0/3 with the destination MAC address of

00:1f:ce:00:00:01.

System also provides mirror divider, that is, sample packet that can be mirrored and send it to

mirror destination interface to reduce the number of packet to mirror destination interface.

2.3.2 Interface mirror configuration

Interface Mirror configuration command includes:

 Configure mirror destination interface

 Configure mirror source interface

 Display interface mirror
