Network Management Using Snmp - ZyXEL Communications P-660HN-T1A Support Notes

8. Network Management Using SNMP


ZyXEL SNMP Implementation
ZyXEL currently includes SNMP support in some P-660HN-T1A routers. It is
implemented based on the SNMPv1, so it will be able to communicate with
SNMPv1 NMSs. Further, users can also add ZyXEL's private MIB in the NMS
to monitor and control additional system variables. The ZyXEL's private MIB
tree is shown in figure 3. 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:
1. coldStart (defined in RFC-1215) :
If the machine coldstarts, the trap will be sent after booting.
2. warmStart (defined in RFC-1215) :
If the machine warmstarts, the trap will be sent after booting.
3. linkDown (defined in RFC-1215) :
If any link of IDSL or WAN is down, the trap will be sent with the port
number . The port number is its interface index under the interface
group.
4. linkUp (defined in RFC-1215) :
