Table 7-2. Error responses
Server responded with | Explanation |
|---|
Contained under subtree | snmpwalk returns this error if you have tried going down a MIB tree and are already at the end, or if the tree doesn't exist on the client. |
No response arrived before timeout | Possible causes include an invalid community name, an agent that is not running, or an inaccessible node. |
Agent reported error with variable | You are trying to set to an object with a datatype that is not the same as (or close to) the variable's specified type. For example, if the variable wants a DisplayString, you'll get this error if you send it an INTEGER. Read through the MIB to see what SYNTAX type the variable needs. |
Missing instance value for... | When you are setting a value, you must supply the entire OID and instance. A scalar object will end with zero (0) and a tabular object will end with the instance number of the object in a table. Verify that the instance number you're using with snmpget is correct and retry your set. |
Access is denied for variable | This may happen if you are trying to set a value on a read-only object. Review the MIB to see what the object's ACCESS setting is. |
