Hi Dwayne,

I cant get snmp walk to connect to the
switch at all.  
Ive configured snmp on the switch everywhich way I can and still cant
get anything info from it.  
From this I assume you've not even been able to get the command linetoolset to work?
For example "snmpstatus -v 2c -c public 192.0.2.1" gives nothing? If itgives a segfault that's sometimes a way of saying there's an OIDview/filter in place on the switch which needs to be removed.
In any case, if you cannot get the command line tools to work thenindeed Netdisco will not work either, as it uses the same libraries androutines.
regards,
oliver.

Use of uninitialized value in concatenation (.) or string at
/home/netdisco/perl5/lib/perl5/App/Netdisco/Util/SNMP.pm line 139.
It could be a YAML formatting error in your configuration file. Thereisn't any formatting checking or validation in Netdisco 2 so the configneeds to be correct.
Are you able to use pastie.org to share the SNMP config in yourdeployment.yml file (changing the secrets, obviously)?
You can also run the same command above but add the -D flag for debugand also set environment variable SHOW_COMMUNITY=1 to show what Netdiscois reading as the SNMP community.

Here is the output from debug command lines.  The error is a result of my
deployment.yml file not getting read when I restart, so IM pretty sure I
have an error there somewhere.  Seems that pastebin is offline right now.
Ill paste my file and email back:
SHOW_COMMUNITY=1 ~netdisco/bin/netdisco-do discover -d 10.40.1.1 -DIQ

If I add the snmp community public RO to my switch config it works fine.
However, that doesnt fix the 4500 x issue.  Im going to update the IOS on
my 4500 and see if it allows me to connect.

Here is the contents of my deployment.yml file in case there is something
real obvious:
