| Subject: | Error index |
I found a bug in the PDU.pm, in which Net::SNMP will give out a bogus
error message. I discovered this problem trying to query a Motorola
VoIP modem. Here's the error message:
ERROR: Cannot get SNMP data (GI-BTI-MIB::btiUpsStatus.0 ->
1.3.6.1.4.1.1166.1.200.4.3.0): Received noError(0) error-status at
error-index 1
While I'm pretty sure the Motorola is misbehaving with the way it
outputs an error-index on a good packet, the module really shouldn't
spit out an error message, if the error-status is "noError". I have
seen another case of this error in PerlMonks as well:
http://www.perlmonks.org/?node_id=581453.
I have fixed this issue by removing the error_index check in the error
routine. This is confirmed to still be a problem in the latest 5.2.0
branch. Here is the modified patch:
