  • Comment: Support SNMPv3

    The support is present in CVS. Fallback from SNMPv3 to SNMPv2 during discovery doesn't work, you have to either default to v3 and then list all your v2 devices explicitly, or default to v3 and list all your v3 devices explicitly.

  • Comment: PoE code assumes power consumption of 12.95W per port

    Ah, I originally wrote this against older 3750s that couldn't measure their own output, and had no MIB where they would report the CDP-negotiated power level per port, so the 802.1af-reported values were the best I could do. This may require another table for device-power info instead of just device-port-power, and fun logic to decide which value to use.

  • Comment: python Varbind doesn't separate iid from tag properly

    I've updated the diff to just use the same regexp as the perl module does, which fixes both the performance and the correctness problems. I still wouldn't write the regexp that way in either language, but it works well enough to leave it alone.

  • Comment: python Varbind doesn't separate iid from tag properly

    We finally tracked down some severe performance problems in our test infrastructure, and lo and behold it was due to this regexp. Something in its complexity results in some incredible exponential factor based upon the length of the object name -- Regex match against tag ifName took 0.000045 seconds Regex match against tag icmpInMsgs took 0.002264 seconds Regex match against tag...

  • Comment: CiscoPower mib dose not load: wrong object?

    Check your CISCO-POWER-ETHERNET-EXT-MIB for its LAST-UPDATED -- is it 200612190000Z? That revision added the cpeExtPsePortTable which this module needs. This version is in the netdisco-mibs 0.4 distribution, or of course at Cisco's site.
