Bridging

Figure 4-7. 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

Bad Addresses

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

Bad Controls

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

Packets Too Long

The 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.

The task of both packet types is to get the destination station to return speciÞc route information to the sending station by including an identiÞer for each ring the explorer packet traversed and for each bridge between any rings BridgingBridging Basics About Source Route-Translational Bridges About Source Route-Transparent BridgesBridging Bridging BasicsBridging For data that is restricted to the Token Ring networks available from the SR-TB bridgeÕs front panel, the bridging method used is user-conÞgurable via local management to be Source Route-only bridged packets must include RIF information and will be source routed no transparent bridging is enabled, Source Route-Transparent bridging method will be determined by whether the RII bit is set, or Transparent only no source routed packets will be bridged.
