Duplicate Network Address
A separate table showing duplicate network addresses is available. Press the
button on the Data View or Capture View toolbar to see this table.
Counter
Duplicate Network Address is a counter of all duplicate network addresses over a
period of time per segment. A count of all duplicate network addresses displays in
the
Overview counters of Expert View. A threshold for this counter can be set in
Expert Alarms for all duplicate network addresses.
IP address 0.0.0.0 is not counted as a duplicate address.
Expert Symptom
Duplicate network addresses are automatically logged as either “Duplicate IP
Address” or “Duplicate IPX Address” expert symptoms. The
Symptom Summary
field provides information about the duplicate IP or IPX address. For example:
Addr=[206.250.228.67]
