Figure 2-7. PPP Link Statistics Window

Each of the errors and statistics related to the PPP Link at the selected bridging interface is described in detail below.

Errors

Indicates the errors that occurred which relate to the PPP Link at the selected bridging interface. Possible error types are:

¥Bad AddressesÑThe Bad Addresses Þeld displays the number of packets received with an incorrect Address Þeld.

¥Bad ControlsÑThe Bad Controls Þeld displays the number of packets received on the selected interface that have an incorrect Control Þeld.

¥Packets Too LongÑThe Packets Too Long Þeld displays the number of received packets that were discarded because their length exceeded the MRU (Maximum Receive Unit). Note that packets that are longer than the MRU and that are successfully received and processed are not included in the count.

¥Bad FCSsÑThe Bad FCSs Þeld displays the number of received packets that were discarded due to having an incorrect FCS (Frame Check Sequence) value.
