Packets Received (Header Errors)
The number of IP data packets received and discarded due to errors in IP headers, including bad
checksums, version number mismatches, other format errors, etc.
Packets Received (Address Errors)
The number of IP data packets received and discarded because the IP address in the destination field was
not a valid address for the VPN Concentrator. This count includes invalid addresses (e.g., 0.0.0.0 ) and
addresses of unsupported classes (e.g., Class E).
Packets Received (Unknown Protocols)
The number of IP data packets received and discarded because of an unknown or unsupported protocol.
Packets Received (Discarded)
The number of IP data packets received that had no problems preventing continued processing, but that
were discarded (e.g., for lack of buffer space). This number does not include any packets discarded while
awaiting reassembly.

Packets Received (Delivered)

The number of IP data packets received and successfully delivered to IP user protocols (including ICMP)
on the VPN Concentrator; i.e., the VPN Concentrator was the final destination.

Packets Forwarded

The number of IP data packets received and forwarded to destinations other than the VPN Concentrator.

Outbound Packets Discarded

The number of outbound IP data packets that had no problems preventing their transmission to a
destination, but that were discarded (e.g., for lack of buffer space).

Outbound Packets with No Route

The number of outbound IP data packets discarded because no route could be found to transmit them to
their destination. This number includes any packets that the VPN Concentrator could not route because
all of its default routers are down.
