Hello, everyone!
1. The mirror port command is used to configure the mirror of an Ethernet port. When you need to copy the traffic of a port to other ports to perform traffic observation, network faulty diagnosis, and data analysis, run this command. After the mirror of an Ethernet port is set, the packets of the mirror source port are copied to the mirror destination port.
command： mirror port src-portid dst-portid mirror-direction
To mirror the received packets of Ethernet port 0/9/0 to port 0/9/1, do as follows:
huawei(config-if-giu-0/19)#mirror port
{ src-portid<U><0,1> }:0
{ dst-portid<U><0,1> }:1
{ mirror-direction<E><ingress,egress,all> }:ingress
Command:
mirror port 0 1 ingress
2. The traffic-mirror command is used to mirror the packets that match an ACL filtering rule on a specified port. To monitor the received or transmitted packets of a port so that you can maintain devices or locate faults, run this command to mirror the packets to be monitored on the port to another port.
Assume that the source port you want to mirror is in 0/20/0, and the destination port is 0/19/0
A) first to check the user IPTV flow

b) Follow the IP/MAC address mirroring messages such as LSW. If there is an aggregation port, you need to configure the Traffic-mirror on each source port
huawei(config)# acl 3000
huawei (config-acl-adv-3000)# rule 1 permit ip destination x.1.1.1 0
huawei (config)#traffic-mirror inbound link-group 3000 rule 1 port 0/20/0 to port 0/19/0
c) Remove port mirroring when positioning is complete
huawei (config)#undo traffic-mirror inbound link-group 4000 rule 1 port 0/20/0
3. Service flow remote mirroring, which is uploaded to the configured server by remotely capture the service Board user-side message or capture a protocol message that has been handed over to the CPU of the main control panel.
MA5600T(diagnose)%%file-server auto-backup board-info primary [server-ip] tftp
MA5600T(diagnose)%pture service-port [service-port index] capture-count 1000000 capture-time 2000
Remove port mirroring when positioning is complete：
MA5600T(diagnose)%%undo capture service-port
MA5680T(diagnose)%%undo file-server auto-backup board-info primary
Thank you.
