9T122-08 Module Specific Information
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.
