3. ZyXEL SNMP Implementation
ZyXEL currently includes SNMP support in some Prestige routers. It is implemented based on the SNMPv1, so
it will be able to communicate with SNMPv1 NMSs. For SNMPv1 operation, ZyXEL permits one community
string so that the router can belong to only one community and allows trap messages to be sent to only one
NMS manager.
Some traps are sent to the SNMP manager when anyone of the following events happens:
•
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.
