Usage Guidelines

Statistics about the discarded packets that carry source-route options are collected only on the MPU. Therefore, if slot slot-id is specified in the command to view statistics on an LPU, the number of discarded packets that carry source-route options displayed in the command output is 0.

If the bad protocol and no route field values in the command output increase quickly, the device receives many IP packets of unknown protocol types and IP packets for which no correct route can be found. In this case, check whether the device is attacked by connected downstream devices.

Example
