Known Affected Releases

3.5.2.BASE 3.5.4.BASE

Description (partial)

Symptom:
You can see input drops under the interface counters where it is hard to match up where they are coming from.  Typically you would look at PSE statistics and/or netio drops.  The multicast TTL expired packets are being counted as drops under interface statistics but not being broken out correctly under the netio drop statistics. 

Conditions:

The router would have to have multicast traffic coming in with a TTL of zero.
