Cabletron Systems 2.2 manual Statistics

Bridging

¥Total ErrorsÑThe Total Errors Þeld displays the total number of errors of all types: Bad Addresses, Bad Controls, Packets Too Long, and Bad FCSs.

Statistics

Lists statistics Þelds which are related to the PPP Link at the selected bridging interface. Possible statistics Þelds are:

¥Local MRUÑThe Local MRU Þeld displays the current value of the MRU (Maximum Receive Unit) for the local PPP entity. This value is the MRU that the remote entity uses when sending packets to the local PPP entity. The MRU is the maximum length of data information (included ÒpaddedÓ data octets, but excluding the Protocol Þeld which identiÞes the datagramÕs protocol type) that can be received by this interface. The default MRU size is 1500 octets. The auto-negotiation process may establish another value for MRU if consent is given at both ends of the PPP link (if either the local or remote PPP entity informs the other that larger packets can be sent, or requests that smaller packets be sent).

¥Remote MRUÑThe Remote MRU Þeld displays the current value of the MRU (Maximum Receive Unit) established for the remote interface at the other end of the PPP Link. This value is the MRU that the local entity uses when sending packets to the remote PPP entity.

¥Local to Peer ACC MapÑThe Local to Peer ACC Map Þeld displays the current value of the Asynchronous Control Character (ACC) Map used for sending packets from the local PPP entity to the remote PPP entity. In effect, this is the ACC Map that is required to ensure that all characters can be successfully transmitted through the local modem. The actual ACC Map used on the transmit side of the link will be a combination of the local nodeÕs pppLinkConÞgTransmitACCMap and the remote nodeÕs pppLinkConÞgReceiveACCMap.

¥Peer to Local ACC MapÑThe Peer to Local ACC Map Þeld displays the Asynchronous Control Character (ACC) Map used by the remote PPP entity when transmitting packets to the local PPP entity. In effect, this is the ACC Map that is required to ensure that the local modem will successfully receive all characters. The actual ACC Map used on the receive side of the link will be a combination of the local nodeÕs pppLinkConÞgReceiveACCMap and the remote nodeÕs pppLinkConÞgTransmitACCMap.

¥Local to Remote Protocol CompressionÑThe Local to Remote Protocol Compression Þeld determines whether or not the local PPP entity uses Protocol Compression when transmitting packets to the remote PPP entity.

¥Remote to Local Protocol CompressionÑThe Remote to Local Protocol Compression Þeld determines whether or not the remote PPP entity uses Protocol Compression when transmitting packets to the local PPP entity.

¥Local to Remote AC CompressionÑThe Local to Remote AC Compression Þeld determines whether or not the local PPP entity uses Address and Control (AC) Compression when transmitting packets to the remote PPP entity.
