How can monitor bridged SXT Bandwith with snmp?

HI

I’m using this article (http://www.wispforum.net/entry.php?6-How-to-Connect-two-Mikrotik-SXT-5D-s-In-Bridge-Mode-Part-II) to configure two SXT’s in bridge mode.

Now I want to monitor bandwidth of this SXT with MRTG. but i don’t know how get access to SNMP of SXT in bridge mode. Please let me know if there is a way.

for SNMP you will need working OSI layer3 for that you can add management IP addresses to these SXT units so they can be managed by you.
