Interface Errors and Discards
Interface Errors and Discards report reveals interface error and discard data. A packet can have more than one error.
- . Device hostname, IP address, or custom label. This is the host where the interface is configured.
- . Text string associated with interface.
- . Packet error count on transmit.
- . Packet error count on receive.
- . Count of packets abandoned at transmit time.
- . Count of received packets discarded.
