P-202H Plus v2 Support Notes
The SNMPv1 messages contains two part. The first part contains a version and a
community name. The second part contains the actual SNMP protocol data unit
(PDU) specifying the operation to be performed (Get, Set, and so on) and the
object values involved in the operation. The following figure shows the SNMPv1
message format.
The SNMP PDU contains the following fields:
•
PDU type Specifies the type of PDU.
•
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.
•
Variable-bindings Associates particular object with their value.
2. ZyXEL SNMP Implementation
ZyXEL currently includes SNMP support in some P-202H Plus v2 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:
