# IP Statistics

## Navigation

1. Right-click on the Persistent Storage Device (PSD) card and then select PSD Details.

2. In the contents pane, double-click on the Statistics folder and then select IP Statistics.

From the IP Statistics dialog box, you can evaluate the performance of this system by monitoring IP traffic activity.

This dialog box displays the following data:

- Datagrams Received (ipInReceives)

- Header Errors (ipInHdrErrors)

- Address Errors (ipInAddrErrors)

- Unsupported Protocol Errors (ipInUnknownProtos)

- In Discards (ipInDiscards)

- Delivered Datagrams (ipInDelivers)

- Out Requests (ipOutRequests)

- Out Discard (ipOutDiscards)

- No Route Datagrams (ipOutNoRoutes)

To monitor these objects in real time, click Monitor.

Datagrams Received (ipInReceives)

Total number of input datagrams received from interfaces, including those received in error.

Header Errors (ipInHdrErrors)

Number of input datagrams discarded because of errors in their IP headers, such as:

- bad checksums

- version number mismatches

- format errors

- time-to-live exceeded errors

- errors discovered during the processing of IP options for a datagram

Address Errors (ipInAddrErrors)

Number of input datagrams discarded because the IP address in their IP header destination field was invalid.

- The value of this object includes invalid addresses and addresses of unsupported classes (for example, Class E).

- For entities that are not IP gateways and therefore do not forward datagrams, the value of this object includes datagrams discarded because the destination address was not a local address.

Unsupported Protocol Errors (ipInUnknownProtos)

Number of locally-addressed datagrams received and discarded because of an unknown or unsupported protocol.

In Discards (ipInDiscards)

Number of input IP datagrams that can be continually processed but were discarded anyway.

The value of this object does not include any datagrams discarded while awaiting reassembly.

Delivered Datagrams (ipInDelivers)

Total number of input datagrams successfully delivered to IP user protocols (including ICMP).

Out Requests (ipOutRequests)

Total number of IP datagrams which local IP user protocols (including ICMP) supplied to IP in transmission requests.

The value of this object does not include datagrams counted in ipForwDatagrams.

Out Discard (ipOutDiscards)

Number of output IP datagrams for which no problem was encountered to prevent their transmission but were discarded anyway.

No Route Datagrams (ipOutNoRoutes)

Number of IP datagrams discarded because no route was found to transmit them through.

The value of this object includes datagrams which could not be routed because a host's default gateways are down.
