Modifying the TB-Min Timer

You can change the TB-Min timer in the PCM from its default value of 100 ms. To do so, use the following command in interface configuration mode:

Command

Purpose

 

 

fddi tb-min milliseconds

Sets TB-Min timer in the PCM.

 

 

Modifying the FDDI Timeout Timer

You can change the FDDI timeout timer in the PCM from its default value of 100 ms. To do so, use the following command in interface configuration mode:

Command

Purpose

 

 

fddi t-outmilliseconds

Sets the timeout timer in the PCM.

 

 

Controlling SMT Frame Processing

You can disable and enable SMT frame processing for diagnostic purposes. To do so, use one of the following commands in interface configuration mode:

Command

Purpose

 

 

no fddi smt-frames

Disables SMT frame processing.

 

 

fddi smt-frames

Enables SMT frame processing.

 

 

Enabling Duplicate Address Checking

You can enable the duplicate address detection capability on the FDDI. If the FDDI finds a duplicate address, it displays an error message and shuts down the interface. To enable duplicate address checking, use the following command in interface configuration mode:

Command

Purpose

 

 

fddi duplicate-address-check

Enables duplicate address checking capability.

 

 

Setting the Bit Control

You can set the FDDI bit control to control the information transmitted during the Connection Management (CMT) signaling phase. To do so, use the following command in interface configuration mode:

Command

Purpose

 

 

fddi cmt-signal-bits signal-bits[phy-a phy-b]

Sets the FDDI bit control.
