VPN 3000 Concentrator Series User Guide
Packets Transmitted (Requests)
The number of IP data packets that local IP user protocols (including ICMP) supplied to transmission
requests. This number does not include any packets counted in
Packets Forwarded.
Fragments Needing Reassembly
The number of IP fragments received by the VPN Concentrator that needed to be reassembled.
Reassembly Successes
The number of IP data packets successfully reassembled.
Reassembly Failures
The number of failures detected by the IP reassembly algorithm (for whatever reason: timed out, errors,
etc.). This number is not necessarily a count of discarded IP fragments since some algorithms can lose
track of the number of fragments by combining them as they are received.
Fragmentation Successes
The number of IP data packets that have been successfully fragmented by the VPN Concentrator.
Fragmentation Failures
The number of IP data packets that have been discarded because they needed to be fragmented but could
not be (e.g., because the
Don’t Fragment flag was set).
Fragments Created
The number of IP data packet fragments that have been generated by the VPN Concentrator.
