Checking the mirroring configuration on an S series switch
For an S series switch (except the S1700), you can run the following commands to check the mirroring configuration: - Run the display current-configuration command to check the mirroring configuration in the configuration file of the switch. - Run the display observe-port command to check the observing port configuration. - Run the display port-mirroring command to check the configuration of port mirroring, traffic mirroring, VLAN mirroring, and MAC address mirroring. - Check the MQC-based traffic mirroring configuration and its application. 1. Run the display traffic behavior user-defined [ behavior-name ] command to check the traffic behavior configuration. 2. Run the display traffic classifier user-defined [ classifier-name ] command to check the traffic classifier configuration. 3. Run the display traffic policy user-defined command to check the traffic policy configuration. 4. Run the display traffic policy user-defined policy-name [ classifier classifier-name ] command to check the traffic policy configuration. 5. Run the display traffic-policy applied-record [ policy-name ] command to check the application record of a specified traffic policy. - Check the ACL-based traffic mirroring application. Run the following commands to check statistics on the packets matching rules. Before running these commands, run the traffic-statistic command in the system view or the traffic-statistic command in the interface view to configure the ACL-based traffic statistics collection function. 1. display traffic-statistics interface inbound 2. display traffic-statistics [ vlan vlan-id | interface interface-type interface-number ] inbound 3. display traffic-statistics [ vlan vlan-id | interface interface-type interface-number ] inbound acl { bas-acl | adv-acl | user-acl | acl-name | l2-acl } [ rule rule-id ] 4. display traffic-statistics [ vlan vlan-id | interface interface-type interface-number ] inbound acl ipv6 { bas-acl | adv-acl | acl-name } [ rule rule-id ] 5. display traffic-statistics [ vlan vlan-id | interface interface-type interface-number ] inbound acl { acl-name | l2-acl } [ rule rule-id ] acl { bas-acl | adv-acl | acl-name } [ rule rule-id ]

How to check whether mirroring is configured successfully on S series switches
For S series switches, you can use either of the following methods to check whether mirroring is configured successfully: - Run the display interface brief command to check whether the observing port usage is increased. - Check whether the monitoring and packet capture software (such as Wireshark) on the monitoring device directly connected to observing ports have successfully capture packets.
