Is this possible configuration. Same port 1,3,5 mirror to two different monitor ports "mirror_one" and "mirror_two" ?

create mirror "mirror_one"
configure mirror mirror_one to 10
enable mirror mirror_one
configure mirror mirror_one add port 1 ingress-and-egress
configure mirror mirror_one add port 3 ingress-and-egress
configure mirror mirror_one add port 5 ingress-and-egress

create mirror "mirror_two"
configure mirror mirror_two to 20
enable mirror mirror_two
configure mirror mirror_two add port 1 ingress-and-egress
configure mirror mirror_two add port 3 ingress-and-egress
configure mirror mirror_two add port 5 ingress-and-egress

Before I have done mirror configuration with loop-back port, but for some reason it stopped working.
configure mirror mirror_one to port-list 10,20 loopback-port 32

Looks like you are hitting your max of 2 ingress-egress mirror ports. (see below link for reference).  Do you need ingress-egress for all 3 ports?

You also don't need a mirror defined for each port you plan to mirror to.  One will work as long as you are within the limits of the mirror ports like 2 ingress-egress mirror ports.
