Description (partial)

Symptom:
Object 	        snmpEngineTime
OID 		1.3.6.1.6.3.10.2.1.3
Type	 	INTEGER
Permission 	read-only
Status 	        current
Units 		seconds
Range 	        0 - 2147483647
MIB 		        SNMP-FRAMEWORK-MIB

Description 	
"The number of seconds since the value of
the snmpEngineBoots object last changed.
When incrementing this object's value would
cause it to exceed its maximum,
snmpEngineBoots is incremented as if a
re-initialization had occurred, and this
object's value consequently reverts to zero.
"

** This doesn't occur. snmpEngineBoots doesn't increment on snmpEngineTime exceeding it maximum.

Conditions:
* SNMP poll to the following OID: 1.3.6.1.6.3.10.2.1.2

user@unixserver:~ % snmpwalk -v 2c -c public 10.0.0.1 1.3.6.1.6.3.10.2.1.3
SNMP-FRAMEWORK-MIB::snmpEngineTime.0 = INTEGER: 4137372 seconds
!
user@unixserver2:~ % snmpwalk -v 2c -c public 10.0.0.1 1.3.6.1.6.3.10.2.1.2
SNMP-FRAMEWORK-MIB::snmpEngineBoots.0 = INTEGER: 5



* SNMP object uptime great enough to cause snmpEngineTime to wrap.
