Usage Guidelines

Usage Scenario

To check statistics about IP packets, including sent, received, fragmented, and reassembled packets, run the display ip statistics command. The received packets displayed also include the packets carrying the Source Route options that are received and then discarded.

Precautions

If the bad protocol and no route field values displayed are large, the local device receives a large number of packets of unknown protocols and without routes, check whether the device is being attacked.

Example

The actual command output varies according to the device. The command output here is only an example.
