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.
•
warmStart (defined in RFC-1215) :
If the machine warmstarts, the trap will be sent after booting.
•
linkDown (defined in RFC-1215) :
If any link of WAN is down, the trap will be sent with the port number . The port number is its
interface index under the interface group.
•
linkUp (defined in RFC-1215) :
If any link of WAN is up, the trap will be sent with the port number . The port number is its
interface index under the interface group.
•
authenticationFailure (defined in RFC-1215) :
When receiving any SNMP get or set requirement with wrong community, 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:
