Table 13-8 IP Statistics (continued)
Field | Description |
|
|
ipOutNoRoutes | The number of IP datagrams discarded because no route could be found to trans- |
| mit them to their destination. Note that this counter includes any packets counted |
| in ipForwDatagrams, which meet this |
| includes any datagrams which a host cannot route because all of its default gate- |
| ways are down. |
|
|
ipReasmReqds | The number of IP fragments received which needed to be reassembled at this |
| entity (the switch). |
|
|
ipReasmOKs | The number of IP datagrams successfully re- assembled. |
|
|
ipReasmFails | The number of failures detected by the IP re- assembly algorithm (for whatever |
| reason: timed out, errors, and so forth). Note that this is not necessarily a count of |
| discarded IP fragments since some algorithms (notably the algorithm in RFC |
| 815) can lose track of the number of fragments by combining them as they are |
| received. |
|
|
ipFragOKs | The number of IP datagrams that have been successfully fragmented at this entity |
| (the switch). |
|
|
ipFragFails | The number of IP datagrams that have been discarded because they needed to be |
| fragmented at this entity (the switch) but could not be, for example, because their |
| Don't Fragment flag was set. |
ipFragCreates | The number of IP datagram fragments that have been generated as a result of |
| fragmentation at this entity (the switch). |
|
|
ipRoutingDiscards | The number of routing entries, which were chosen to be discarded even though |
| they are valid. One possible reason for discarding such an entry could be to free- |
| up buffer space for other routing entries. |
|
|
ipDefaultTTL | The default value inserted into the |
| header of datagrams originated at this entity (the switch), whenever a TTL value |
| is not supplied by the transport layer protocol. |
|
|
ipReasmTimeout | The maximum number of seconds, which received fragments are held while they |
| are awaiting reassembly at this entity (the switch). |
