Not a bad idea, but it helps only in this special case. For the generic
case you need to extract the relevant ifIndex values from the Ascend
box and build a MRTG target line on the fly. I've posted a scotty
script that is a starting point for this task to this list a while
ago, however:

1) It works only on Maxen. I haven't checked why it fails on Pipes, may
   be as simple as the sessionActiveTable is not available there.
2) It doesn't have the ability to collect sessions yet.

Both problems may eventually be fixed easily by someone who knows a bit
of SNMP and isn't offended by programming in TCL. I likely stay away
from it until more straight mechanisms to retrieve this information are
available in the firmware (probably 6.0). The WAN MIB looks nice ;)
If it gets on its feet it is eventually possible to hack this directly
into MRTG as a special syntax, f.i.:

Target[some-line]: ascend-profile%some-line:public@max
