Class SnmpTarget

java.lang.Object

com.h3c.util.snmp.SnmpTarget

public class SnmpTarget
extends Object

SNMP Target. This object is immutable to the creator. It is updated internally to store V3 discovery parameters. It is still thread-safe because all the V3 discovery related methods are synchronized. TODO: Important note the engine time is being incremented as time goes by but the engine boots is not. If a SnmpTarget is cached and the device reboots a SNMPv3 discovery must be sent again. Revisit this later or provide documentation. Maybe: fix for PCM is to keep track of when the discovery was made and mark the target stale. Actually what was happening is that the device was rebooted and so the bootCount was out of sync. When traffic issued a set, the device responding with no error but the V3 discovery "report". We will have to handle this and/or document that you can not have long lived SnmpTargets (>= 3 minutes) TODO: The actual fix was to clear out the target cache when a USM_ERROR is detected. Be careful because for walks (bulk or normal) the response VB count does not match the request VB count and you may short circuit the error handling code before you get to the USM_ERROR. This needs to be unit tested: 1) Set up device in V3 with a target 2) Reboot the device 3) Attempt to communicate with the target (should reset and rediscovery engine time and boot counts)
