• Request ID Associates requests with responses.
• Error status Indicates an error and an error type.
• Error index Associates the error with a particular object variable.

2. ZyXEL SNMP Implementation
ZyXEL currently includes SNMP support in some P-202H Plus v2 routers. It is

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
