This article shows that IPv6 port mirroring is not supported on J Series and SRX devices.

A user wants to configure port-mirroring for IPv6.

In the “set forwarding-options port-mirroring family” hierarchy, the inet6 parameter is missing.

[edit forwarding-options port-mirroring]
root@650-2# set family ?
Possible completions:
> inet Mirror IPv4 packets

The inet6 is a hidden command.

Even though you can configure inet6 explicitly, you will get an unsupported platform error.

IPv6 port-mirroring is not supported on J Series or SRX devices, as shown below:

J Series example:

[edit forwarding-options]
root@j2350-1# show
port-mirroring {
##
## Warning: configuration block ignored: unsupported platform (j2350)
##
    family inet6 {
        output {
            interface ge-0/0/0.0;
        }
    }
}

SRX example:

[edit forwarding-options]
root@650-2# show
port-mirroring {
##
## Warning: configuration block ignored: unsupported platform (srx650)
##
    family inet6 {
        output {
            interface ge-0/0/0.0;
        }
    }
}
