Sample output from SNR-S2990G-24FX:
hostname#show interface ethernet 1/0/25
Interface brief:
Ethernet1/0/25 is up, line protocol is up
Ethernet1/0/25 is layer 2 port, alias name is #UPLINK# to <skip>, index is 25
**Hardware is SFP+, address is f8-f0-82-75-86-1d**
PVID is 1
Current get_interfaces script crashes when it sees unknow interface type, so interface discovery was totally broken. My fix impements SNR-S2990G-24FX support. Also it was tested in my enviroment on other SNR switches.
