[j-nsp] EX3300, redundant-trunk-group and SNMP

[Ivan Malyarchuk]

Hi,
I use feature "redundant-trunk-group" on EX3300 stack.
It is working OK, and i can check status of Active/Backup interfaces in 
CLI with show redundant-trunk-group :
 > show redundant-trunk-group
Group name      Interface   State       Time of last flap 
       Flap count
uplink     xe-0/1/1.0  Up/Pri/Act  Never 
      0
            xe-2/1/1.0  Up          Never 
       0

But I cant find corresponding SNMP OID for this subsystem. Does it 
exists? (EX3300, Junos 15.1R5.5)

If not, is there any alternatives for making Active/Backup uplink group 
which can be monitored via SNMP? (There is some vlans from uplinks, so 
no pure layer3 possible, and no xSTP: any BPDUs, including PVST are dropped)
