VPN 3002 Hardware Client Reference

OL-1893-01

Chapter 13      Monitoring

Monitoring | Statistics | MIB-II | IP

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 3002 could not route because all of its 
default routers were down.

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 3002 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 3002.

Fragmentation Failures

The number of IP data packets that have been discarded because they needed to be fragmented but could 
not be (because the Don’t Fragment flag was set).

Fragments Created

The number of IP data packet fragments that have been generated by the VPN 3002.
