SNMP supported MIBs
You can use the SNMP supported MIBs reference to find information on the standard and extension MIB specifications, and trap configuration.
SNMP Agent failure report trap contents
A standard extension trap protocol data unit (PDU) includes the product number of the device that experienced the failure, the device nickname, and a failure reference code. A failure report trap contains additional information about the failure, such as the area, date, and time of the failure.
If you obtain the information with the GetRequest command, access the MIB by using the product number of the device as an index.
The following table shows the failure report trap.

2. The object identifier for a failure in a storage system processor would be .1.3.6.1.4.1.116.5.11.4.1.1.6.1.2. | |||
SNMP Agent extension trap types
SNMP Agent extension trap types are set according to the severity. The character strings following "RaidEventUser" indicate their severity.
The following table describes the SNMP Agent extension trap types.

Standard MIB specifications
MIBs supported by SNMP Agent
SNMP Agent supports a limited number of MIBs. If you send a GET request for an object (MIB) that is not supported, you will receive NoSuchName as a GET RESPONSE.
The following table lists MIBs and indicates whether they are supported.
|
MIB |
Support | |
|
Standard MIB: MIB-II |
system group |
Yes |
|
interface group |
No | |
|
at group | ||
|
ip group | ||
|
icmp group | ||
|
tcp group | ||
|
udp group | ||
|
egp group | ||
|
snmp group | ||
|
Extension MIB |
Yes | |
SNMP Agent MIB access mode
The access mode for MIB in all communities is read only. If you send a GET request for a SET REQUEST operation, you will receive NoSuchName as a RESPONSE.
Example object identifier system
The following figure shows an example object system supported by SNMP Agent.
MIB mounting specifications supported by SNMP Agent
SNMP Agent supports two MIB mounting specifications.
The supported MIB mounting specifications are as follows:
- mgmt OBJECT IDENTIFIER ::= {iso(1) org(3) dod(6) internet(1) 2 }
- mib-2 OBJECT IDENTIFIER ::= {mgmt 1}
An SNMP Agent mounts only system groups in mib-2, as shown in the following table.
|
Name |
Description |
Mounted value |
|
sysObjectID {system 2} |
This is the product identification number. |
1.3.6.1.4.1.116.3.11.4.1.1 (fixed) |
|
sysUpTime {system 3} |
An accumulated time from an SNMP agent. |
Unit: 100 ms |
|
sysContact {system 4} |
A manager who manages an agent or a contact address. |
Maximum 180 characters in an ASCII characters string. Input by a user from an SNMP setting window.* |
|
sysName {system 5} |
The name of an agent manager |
Maximum 180 characters in an ASCII characters string. Input by a user from an SNMP setting window.* |
|
sysLocation {system 6} |
An agent setup location. |
