Mirroring can be used for troubleshooting or data collection. Typically it is used for troubleshooting to investigate certain things not working correctly. You enable mirror on the port experiencing issues and mirror to another port with Wireshark active.

Port mirroring configures the switch to copy all traffic associated with one or more ports or VLANS to another port so it can be connected to a network analyzer or RMON probe for packet analysis.

#Takes ingress traffic from vlan "Default and mirrors it to port 1
conf mirror add vlan "Default" ingress
conf mirror to port 1
enable mirror

#Takes ingress and egress traffic from port 2 and mirrors it to port 1
conf mirror add port 2 ingress-and-egress
conf mirror to port 1
