SRT Configuration Screen Fields
The following information briefly explains each SRT Configuration Screen field.
Bridge Number
Allows you to enter a hexadecimal number that uniquely identifies a bridge when
more than one bridge is used to span the same two segments. Valid bridge
numbers range from 01 to 0F (15).
Interface
Lists each bridge interface on the selected module: FNB, TR1, and TR2.
Ring Number
Allows you to set the hexadecimal number that uniquely identifies the ring to
which the specified interface is connected. Valid ring numbers range from 001 to
FFF.
Hop Count
Allows you to set the maximum number (1 through 6) of routing descriptors
allowed in All Routes or Spanning Tree Explorer frames.
Bridge Method (Toggle)
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 filtered 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 filtered when they are received.
