| Configuring the WSM using Device Manager |
The following table describes the fields on the WSM Blade--IP tab.
In Receives
The number of input datagrams received from interfaces, including those received in error.
In Header Errors
The number of input datagrams that were discarded because of errors in the IP headers. Errors: bad checksums, version number mismatch, other format errors, time-to-live exceeded, errors discovered in processing their IP options, and so on.
In Address Errors
The number of input datagrams that were discarded because the IP address in the IP header's destination field was not a valid address at this WSM. Invalid addresses: 0.0.0.0, addresses of unsupported Classes such as Class E, and so forth. For entities that are not IP Gateways that do not forward datagrams, the count includes datagrams that were discarded because the destination address was not a local address.
Forward Datagrams
The number of input datagrams for which this entity was not their final IP destination. An attempt was made to find a route to forward them to that final destination. In entities that do not act as IP Gateways, the count only includes packets that were Source-Routed via this entity, and that the Source-Route option processing was successful.
Packets In with Unknown Protocol
The number of locally-addressed datagrams that were received successfully, but were discarded because of an unknown or an unsupported protocol.
In Discards
The number of input IP datagrams that were discarded, although no errors were identified. This can occur because of insufficient buffer space. This counter does not include any datagrams that were discarded while waiting for re-assembly.
In Delivers
The total number of input datagrams successfully delivered to IP user-protocols, including ICMP.
Out Requests
The total number of IP datagrams that local IP user-protocols, including ICMP, supplied to IP in requests for transmission. This counter does not include any datagrams that were counted in Packets Routed.
Out Discards
The number of output IP datagrams that were discarded, although no problems were noted. This can occur because of insufficient buffer space. This counter includes datagrams that were counted in Packets Routed if the packets met this discard criterion.
Out Discards No Routes
The number of IP datagrams discarded because no route was available for transmitting them to their destinations. This counter includes any packets counted in Packets Routed that meet this no-route criterion. Also included are any datagrams that a host cannot route because all default gateways are down.
Fragments OK
The number of IP datagrams that have been successfully fragmented.
Fragments Failed
The number of IP datagrams that have been discarded because they could not be fragmented, such as when the Don't Fragment flag has been set.
Fragments Created
The number of IP datagrams that have been fragmented.
Fragment Reassembly Required
The number of received IP fragments that needed to be reassembled.
Fragment Reassembly OK
The number of IP datagrams successfully reassembled.
Fragment Reassembly Failed
The number of failures detected by the IP re-assembly algorithm. Possible failures include timed out, errors, and so on. Note: This is not necessarily a count of discarded IP fragments. Some algorithms, notably the algorithm in RFC 815, can lose track of the number of fragments by combining them as they are received.
Routing Discards
The number of dropped packets.
