Introduction to fxos-mibs-fp2k.2.6.1.133.zip
This SNMP Management Information Base (MIB) package provides critical monitoring updates for Cisco Firepower 2100/4100 Series appliances running FXOS 2.6.1 firmware. Released through Cisco’s standard maintenance channel on August 15, 2020, the update resolves SNMPv3 compatibility issues with third-party network monitoring systems while enhancing hardware health tracking capabilities.
The package specifically addresses OID mapping conflicts identified in Firepower 4110/4120/4140 platforms during high-availability deployments. Network operations teams can now monitor advanced threat inspection metrics through enhanced SNMP traps and object definitions compatible with SolarWinds, Nagios, and Cisco Prime Infrastructure.
