Note：Egress mirror works correctly only on those switches that the parameter 'egress mirror' is true.According to above chips,3290（Firebolt3),3296(Triumph2),helix4 support egress mirror.On other switches,the mirror port' traffics' action are not certain.

Create One Mirror

ovs-vsctl [--OPTION] -- set bridge <bridge> mirrors=@m -- --id=@<port1> get Port <port1> -- --id=@<port2> get Port <port2> [-- --id=@<port3> get Port <port3>]-- --id=@m create Mirror name=<mirror-name> select-src-port=@<port1>[,@<port3>] select-dst-port=@<port1>[,@<port3>] output-port=@<port2>

PicOS OVS supports mirroring, select-src-port and select-dst-port represent the source ports of mirroring, select-dst-port means some packets (in switch chip) will go-out from the specified port (egress); select-src-port means some packets will enter the specified port (ingress); output_port means the monitor port. PicOS OVS supports up to 4 mirrors.

Before PicOS2.10 ovs only support configure physical port as output_port, from PicOS2.10 ovs also support lag interface as output_port.

Example1:
Add port ge-1/1/1, ge-1/1/2 and ge-1/1/3 to mirror, ge-1/1/1 and ge-1/1/2 as ingress and egress, the output port is ge-1/1/3.

root@PicOS-OVS$ovs-vsctl set bridge br0 mirrors=@m -- --id=@ge-1/1/1 get Port ge-1/1/1 -- --id=@ge-1/1/2 get Port ge-1/1/2 -- --id=@ge-1/1/3 get Port ge-1/1/3 -- --id=@m create Mirror name=mymirror select-src-port=@ge-1/1/1,@ge-1/1/2 select-dst-port=@ge-1/1/1,@ge-1/1/2 output-port=@ge-1/1/3

Example2:
Add port ge-1/1/1, ge-1/1/2 and ae1 to mirror, ge-1/1/1 and ge-1/1/2 as ingress and egress, the output port is ae1.

root@PicOS-OVS$ovs-vsctl set bridge br0 mirrors=@m -- --id=@ge-1/1/1 get Port ge-1/1/1 -- --id=@ge-1/1/2 get Port ge-1/1/2 -- --id=@ae1 get Port ae1 -- --id=@m create Mirror name=mymirror select-src-port=@ge-1/1/1,@ge-1/1/2 select-dst-port=@ge-1/1/1,@ge-1/1/2 output-port=@ae1

ovs-vsctl [--OPTION] destroy <table> <record> – clear Bridge <bridge> mirrors

Example:

Delete a mirror named mymirror from mirror table in bridge br0.

admin@PicOS-OVS$ ovs-vsctl destroy Mirror mymirror -- clear Bridge br0 mirrors
or
admin@PicOS-OVS$ ovs-vsctl clear Bridge br0 mirrors

Create Two Mirrors

admin@PicOS-OVS$ovs-vsctl  -- set bridge br-s mirrors=@m,@m1 -- --id=@ge-1/1/1 get Port ge-1/1/1 -- --id=@ge-1/1/3 get Port ge-1/1/3 -- --id=@m create Mirror name=mymirror select-src-port=@ge-1/1/1 output-port=@ge-1/1/3 -- --id=@m1 create Mirror name=mirror1 select-src-port=@ge-1/1/3 output-port=@ge-1/1/1

Add one mirror and monitor port is lag

admin@PicOS-OVS$ovs-vsctl -- add bridge br-s mirrors @m -- --id=@te-1/1/1 get Port te-1/1/1 -- --id=@te-1/1/2 get Port te-1/1/2 -- --id=@ae1 get Port ae1 -- --id=@m create Mirror name=mymirror select-src-port=@te-1/1/1 select-src-port=@te-1/1/2 output-port=@ae1

Delete one mirror

admin@PicOS-OVS$ovs-vsctl remove bridge br0 mirrors 76fd4479-67e9-4c65-8edb-b99d8706d8f9
