    Just an FYI: 9.0.45.0 was released at the same time as 10.1.1.0 and
    contains the same fixes. The feature set does differ, as Xing wrote.
    But there is an alternative to 10.1.1.0 that is supposedly roughly
    comparable.

    Some tech info:

    10.1.1.0 has only been released for Alteon 184/AD4 systems so far.
    Moreoever, this version removes bandwidth management (BWM) functionality

    due to "limited memory" as quoted by the release docs. I think Alteon
    just
    got fed up bug fixing BWM? =)

    Rick's suggestion is sound. Rather than go SNMP, use a croned perl/php
    TELNET client from a nearby server to do a regular dump capture or send
    TFTP dump commands would be cleaner as well. At least this way, any
    problem
    you encounter would be well documented/debugged by Nortel.
