ZyXEL Communications Prestige 2302RL Support Notes page 71

Currently, some Prestige models support SNMPv1 that allows the Prestige to communicate with SNMPv1
NMSs. For SNMPv1 operation, ZyXEL allows one community string so that the Prestige can only belong to
one community and allows trap messages to be sent to only one NMS manager.
The following describes some common traps and the corresponding events.

coldStart (defined in RFC-1215) :
If the machine coldstarts, the trap will be sent after booting.

warmStart (defined in RFC-1215) :
If the machine warmstarts, the trap will be sent after booting.

linkDown (defined in RFC-1215) :
If a DSL or WAN link is down, the trap will be sent with the port number . The port number is its
interface index in the interface group.

linkUp (defined in RFC-1215) :
If a DSL or WAN link up, the trap will be sent with the port number . The port number is its interface
index in the interface group.

authenticationFailure (defined in RFC-1215) :
When the wrong community (password) is received for an SNMP get or set operation, , this trap is sent to the
manager.
1. whyReboot (defined in ZYXEL-MIB) :
When the system is going to restart (warmstart), the trap will be sent with the reason of restart before rebooting.
(i) For intentional reboot :
In some cases (such as downloading new files or entering the "sys reboot" command, ...), a system reboot is
done intentionally. And traps with the message "System reboot by user !" will be sent.
(ii) For fatal error :
In case the system has to reboot due to unrecoverable errors. Traps with the error codes will be sent.
