I am polling SNMP data from a list of devices using the SNMP module based off of the Net-SNMP library.

Everything works fine when I make a new SNMP::Session with an IP address that is reachable however if the IP is unreachable the program crashes when I try to get the SNMP data like so...

my $vars = new SNMP::VarList(['sysDescr',0]['sysUpTime',0]);  
my ($descr,$uptime) = $snmp->get($vars);

Which will crash with the follow error...

Can't call method "get" on an undefined value at...

Is there a way to handle this error without crashing?
