Local to Remote Protocol Compression

The 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 Compression

The 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 Compression

The Local to Remote AC Compression Þeld determines whether or not the local

PPPentity uses Address and Control (AC) Compression when transmitting packets to the remote PPP entity.

Remote to Local AC Compression

The Remote to Local AC Compression Þeld determines whether or not the remote

PPPentity uses Address and Control (AC) Compression when transmitting packets to the local PPP entity.

Transmit FCS Size

The Transmit FCS Size Þeld displays the size of the Frame Check Sequence (FCS), in bits, that the local node generates when sending packets to the remote node. Currently, only a 16 bit FCS is supported.

Receive FCS Size

The Receive FCS Size Þeld displays the size of the Frame Check Sequence (FCS), in bits, that the remote node generates when sending packets to the local node. Currently, only a 16 bit FCS is supported.

The Dot5 Errors Statistics Window

The Dot5 Errors menu option invokes the Dot5 Errors Statistics window, which enables you to view IEEE 802.5 error statistics reported for a Token Ring bridge interface.

To access the Dot5 Errors Statistics window

from the Bridge Status window:

1.Click on the desired Port button () to display the port menu.

2.Drag down to select Dot5 Errors…. The device port Dot5 Errors Statistics window, Figure 4-8, will appear.

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 ringsBridging Basics Bridging Basics About Source Route-Transparent BridgesAbout Source Route-Translational Bridges BridgingFor 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.
