8 years ago You are getting the value of "13" from your SNMP agent. When pysnmp tries to map "13" to a symbolic constant for given OID (as defined by F5-BIGIP-LOCAL-MIB) it fails because "13" is not in MIB:
ltmPoolMemberMonitorStatus OBJECT-TYPE
SYNTAX INTEGER {
unchecked(0),
checking(1),
inband(2),
forced-up(3),
up(4),
addr-down(18),
down(19),
forced-down(20),
maint(21),
irule-down(22),
inband-down(23),
down-manual-resume(24)
}May be it's a matter of old MIB so consider upgrading it. Or you could add "13" manually into the MIB, however the semantics of that value would remain unknown.

1.) When just calling something like 'sysDescr' in the SNMPv2-MIB I get results.
Produces:
(None, Integer('noError', NamedValues(('noError', 0), ('tooBig', 1), ('noSuchName', 2), ('badValue', 3), ('readOnly', 4), ('genErr', 5), ('noAccess', 6), ('wrongType', 7), ('wrongLength', 8), ('wrongEncoding', 9), ('wrongValue', 10), ('noCreation', 11), ('inconsistentValue', 12), ('resourceUnavailable', 13), ('commitFailed', 14), ('undoFailed', 15), ('authorizationError', 16), ('notWritable', 17), ('inconsistentName', 18))), Integer(0, subtypeSpec=ConstraintsIntersection(ConstraintsIntersection(), ValueRangeConstraint(0, Integer(2147483647)))), [ObjectType(ObjectIdentity(ObjectName('1.3.6.1.2.1.1.1.0')), DisplayString('BIG-IP 1600 : Linux 2.6.32-431.56.1.el6.f5.x86_64 : BIG-IP software release 12.1.0, build 1.0.1447', subtypeSpec=ConstraintsIntersection(ConstraintsIntersection(ConstraintsIntersection(ConstraintsIntersection(), ValueSizeConstraint(0, 65535)), ValueSizeConstraint(0, 255)), ValueSizeConstraint(0, 255))))])
2.) But when I call another object 'ltmPoolMemberMonitorStatus' from a MIB that is asn1 converted MIB 'F5-BIGIP-LOCAL-MIB' it produces an error:
The only line that changes was the ObjectType line: Note: All required mibs seem to be 'loaded' after 'evaluation'
From: ObjectType(ObjectIdentity('SNMPv2-MIB', 'sysDescr'))) To: ObjectType(ObjectIdentity('F5-BIGIP-LOCAL-MIB', 'ltmPoolMemberMonitorStatus')))

Can you tell me where to find out where the 'failed for "13" is coming form?
When I run this script as 'cont' inside the python debugger (pdb -m ./f5walk.py) I see this message in the "post mortem debugging'
