Setting up a mirrored port

Below will show you how to setup port-mirroring;

Step 1;

Make sure the output port is a generic port, no vlans and or VOIP/tagging.

[edit ethernet-switching-options] + analyzer port-mirror { + input { + ingress { + interface ge-0/0/22.0; + } + egress { + interface ge-0/0/22.0; + } + } + output { + interface { + ge-0/0/21.0; + } + } + }

set ethernet-switching-options analyzer port-mirror input egress interface ge-0/0/22 set ethernet-switching-options analyzer port-mirror input ingress interface ge-0/0/22

set ethernet-switching-options analyzer port-mirror output interface ge-0/0/22

That should do the trick!
