ICMP Parameter Problem
Counter
ICMP Parameter Problem events are counted in the ICMP All Errors counter. A
count of all ICMP errors displays in the
Overview counters of Expert View. A
threshold can be set in Expert Alarms for all ICMP errors.
Expert Symptom
ICMP Parameter Problem events are automatically logged as expert symptoms. The
Symptom Summary field provides information about the IP addresses involved. For
example:
Bad IP Header sent from [206.250.228.11] to
[206.250.228.69]. SA=[206.250.228.11] DA=[206.250.228.69]
This Expert Symptom will be used to identify a parameter problem only if the
problem cannot be identified as a Bad IP Header or as a Missing IP Option.
Diagnostic Details
__________________________________________________________________
Problem Description:
An ICMP Parameter Problem message has been sent.
__________________________________________________________________
Probable Cause(s):
1. A host/router may send this message if the IP header parameters have
problems that prevent processing of the packet.
2. A host/router may have a bad network stack or a bad interface card.
3. There may be incorrect arguments in IP options.
__________________________________________________________________
Recommended Action(s):
1. Check the ICMP Pointer field to see the octet in the IP header where the error
was detected.
2. Verify that the source that sent this IP header has a good network interface
card.
3. Verify that the network stack on the source that sent the bad IP header
parameters is working properly.
