[pmcopoc]

I have multiple sonicwall firewalls and have been successful in using CACTI for review my In/OUT stats except for just one of my sonicwalls. I keep getting timeouts

CMDPHP: Poller[0] WARNING: SNMP Walk Timeout for Host:'192.168.5.1', and OID:'.1.3.6.1.4.1.762.2.5.2.1.1'

I've adjusted the timeout wait period but I'm unable to get any graphs due to timeoutsl
