You should eventually get yourself a good book on SNMP network management
and the MIB structure (no pun intended, it's simply because you miss the
basics). Eventually reading the appropriate RFCs may also help, but it's
harder than reading a book on this stuff. It is a bit complicated, and
finding out all of it by digging in the dark is quite hard (and playing
around with OIDs in numeric _is_ digging in the dark).
However, even with digging you may find your way through. You may, however,
need a SNMP browser that can read MIB files directly and guide you through
without numerics. I would think getting scotty and tkined may be a good
start (ask Archie). With scotty you say:
set s [snmp session -address hostname -community bigbrother]
$s walk x "ascend.sessionStatusGroup.sessionStatusTable.sessionStatusEntry"
...
i.e. you use textual MIB references. Scotty also autolocates stuff at least
in enterprises, mib-2 and ifTable, probably more.
And tkined has a nice MIB browser so after loading the ascend mibs, you
can interactively walk them through and get live feedback including the
documentation as from the mib data. With this tool your problem of
locating the modem MIB stuff is a matter of seconds.
BTW, the mib-2 is not under enterprises, it is the main and most well
standardized part of the SNMPv1 MIB space and resides directly under
mgmt.
