Issue:
Spectrum is asserting the "MANAGEMENT AGENT LOST" alarm on Cisco device models running "Cisco IOS Software [Denali], Catalyst L3 Switch Software (CAT3K_CAA-UNIVERSALK9-M), Version 16.3.1, RELEASE SOFTWARE (fc3) "
Environment:
Cisco devices running "Cisco IOS Software [Denali], Catalyst L3 Switch Software (CAT3K_CAA-UNIVERSALK9-M), Version 16.3.1, RELEASE SOFTWARE (fc3)"  modeled in any version of Spectrum running on any supported operating system
Cause:
Spectrum is sending out snmp requests to the following OID's on these devices:

1.3.6.1.4.1.9.9.48.1.1.1.5 - ciscoMemoryPoolUsed 
1.3.6.1.4.1.9.9.48.1.1.1.6 - ciscoMemoryPoolFree 
1.3.6.1.4.1.232.11.1.1 - cpqHoMibRevMajor 
1.3.6.1.4.1.2.6.159.1.1.30.3.1.1 - ibmSystemComponentHealthKeyIndex 

These OID's are not supported on these devices running "Cisco IOS Software [Denali], Catalyst L3 Switch Software (CAT3K_CAA-UNIVERSALK9-M), Version 16.3.1, RELEASE SOFTWARE (fc3)". The device should immediately respond with "noSuchName". However, when an SNMP query is sent to these OID's, the device stops responding to snmp for over a minute. Since the device does not respond to SNMP for over a minute but does respond to ICMP, Spectrum asserts the "MANAGEMENT AGENT LOST" alarm as expected. 
Resolution:
This is an issue with the SNMP agent on the device and should be addressed by the vendor.
