Bridge Conﬁguration Screen Fields (Screen 2)

The following information brießy explains each Bridge ConÞguration Screen 2

Þeld.

Ring Speed (Toggle)

Allows you to set each token ring interfaceÕs operating speed (either 4 Mbps or 16

Mbps). Press the Space Bar to toggle to the desired value.

Ring Number

Allows you to set the hexadecimal number that uniquely identiÞes the ring to

which the speciÞed interface is connected. Valid ring numbers range from 001 to

FFF.

Hop Count

Allows you to set the maximum number (1 through 7) of routing descriptors

allowed to be forwarded in All Routes or Spanning Tree Explorer frames.

STE Forwarding (Toggle)

Allows you to manually conÞgure whether a Spanning Tree Explorer frame is

forwarded or blocked. Press the Space Bar to toggle to the desired value (either

ENABLE or DISABLE). This is available only with the Spanning Tree Algorithm

(STA) set to NONE.

Bridge Method (Toggle - Available on Token Ring interfaces only)

Displays one of the following bridge methods:

¥ Source Route (SR) - All frames from the FNB are forwarded on the front panel

Token Rings with a source route RIF. There is no transparent frame support.

The Token Ring interface may only receive and transmit SR frames in this

mode. All TP frames are Þltered when they are received by the Token Ring

interface.

¥ Source Route Transparent (SRT) - Performs source route bridging when

required, transparent bridging when required, and translational bridging. The

Token Ring interface can receive and transmit both SR and TP frames.

¥ Transparent (TP) - There is no source routing support. The bridge performs

transparent 802.1d bridging. All SR frames are Þltered when they are received.
