> 
> 	A new version of the SNMP daemon for the T3 network was
> installed on June 26. This version supports MIB-II variables for the
> T/960 ethernet cards (ifInUcastPkts, ifOutUcastPkts, and ifInErrors),
> and also includes enhanced configuration support for monitoring T3
> DSUs.
> 	A new SNMP client for the NOC to control the T1 Cylink ACSUs
> which are part of the T3 backbone has been implemented. This avoids
> use of a separate dial-in connection to these CSUs.

> 	New SNMP variables have been added to furthermonitor the DSU

The new SNMP daemon still does not report the MIB-II variables correctly.
Here is the illustration:
