[j-nsp] SRX reth and Cisco interface

[Jonathan Call]

I have  a very basic configuration but can't get link between a Cisco 3560 and the SRX 240h:
ge-0/0/0 {    description "port 21 on 3560 switch";    gigether-options {        redundant-parent reth1;    }}...reth1 {    redundant-ether-options {        redundancy-group 1;    }    unit 0 {        family inet {            address 192.168.0.1/24;        }    }}
Port 21 on the Cisco switch does not have any configuration at all. The site is still being built so the HA member has not been set up yet.
