[mrtg] cfgmaker doesn't work with Palo Alto firewalls

[ditto at pobox.com]

Greetings -

cfgmaker doesn't appear to work with Palo Alto 3020 firewalls
(although it does work with other versions of PA FWs). I'm a bit
perplexed as I've never seen snmpwalk work but cfgmaker fail. Here are
the relevant versions and output.

Thanks in advance!

$ cfgmaker --version
cfgmaker for mrtg-2.17.4

$ snmpwalk --version
NET-SNMP version: 5.5

snmp-walk output

$ snmpwalk -v2c pa-3020-fw -c comname sysName
SNMPv2-MIB::sysName.0 = STRING: pa-3020-fw

cfgmaker output
