Hi,
I'm currently writing a Perl script using the Net-SNMP Perl API included in the
lastest release 5.3.0.1. But I have a little problem, and any help would be
greatly appreciated. :-)
I have to make various SNMP request to switches, but they are quite
heterogeneous : some of them support only SNMP v1, v2c max, or v3 max. So I
want to find a way to determinate the max version supported by a switch.
Here's the problem : as there is no specific SNMP query returning supported
version(s), I have the idea to use the behavior of the SNMP::Session
constructor which returns an object reference if connection successful or undef
in case of error.
Unfortunately, it doesn't work in the expected way. I have made a test on an old
switch supporting only SNMP v1. When I query it with v3, OK : SNMP::Session->new
returns "undef". But when I query it with v2c, how surprising :
SNMP::Session->new returns me a descriptor... :(
This situation is quite annoying for me. Is this a bug ? Or, if anyone has a
suggestion for a more reliable solution to obtain version, please tell me.
