Interpreting SNMP Error Messages
CiscoView displays the following SNMP error messages, shown in Table 24-15, resulting from failed
command requests in the status bar message area:
Table24-15 SNMP Error Messages
Message
Explanation
timeout
You can no longer reach the device in the time specified in the
CiscoView Properties window.
tooBig
The request that you made cannot fit into a single packet. Generally,
CiscoView splits requests for physical view status until the device can
respond. In certain cases, CiscoView assumes that if an agent times out
on 20 or more variables, the agent might not be capable of responding
because the request is too big; it splits the request and resends it. Check
that the MTU size on the SNMP interface is as large as possible so that
CiscoView does not waste bandwidth by sending more than one
request.
genErr
This is a collective message name for problems that do not have a
unique error message.
noSuchNa
me
A request for a variable was sent to an inaccessible variable. This
occurs if you are not using the correct community string.
badValue
The agent did not respond within the time interval specified by the
timeout/retries field in the CiscoView Properties window. This can also
indicate the use of an incorrect community string.
While performing a set operation on a MIB object, the value specified
for writing does not follow the proper syntax for the MIB object. It
could be because of type mismatches or out-of-range values.
