There are no firewalls involved on this local device, it is a simple Cisco 3550 Switch. I am successfully pulling SNMP data using Zabbix, Spiceworks and have used Cacti previously without issue.

==== SWITCH-10.SWITCH_10 ====
snmpwalk -v2c -cRead 192.168.1.10 system
SNMPv2-MIB::sysDescr.0 = STRING: Cisco Internetwork Operating System Software

That same device correctly shows the interface list and the interface statuses…
