P-660R-F1 Support Notes

7. Network Management Using SNMP

ZyXEL SNMP Implementation

ZyXEL currently includes SNMP support in some P-660R-F1 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) :

If any link of IDSL or WAN is up, the trap will be sent with the port

number . The port number is its interface index under the interface group.

5. authenticationFailure (defined in RFC -1215) :

When receiving any SNMP get or set requirement with wrong community, this trap

is sent to the manager.
