3. ZyXEL SNMP Implementation
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.
Associates requests with responses.
Indicates an error and an error type.
Associates the error with an object variable.
Associates an object with its value.
