Configuring FDDI Services
117020-A Rev. A 3-3
Enabling or Disabling a FDDI Interface
The router enables FDDI line services when you add the interface. You can
disable and enable the interface without moving physical cables.
Enabling or Disabling BofL Messages
With BofL enabled, the router sends polling messages from this interface to all
systems on the local network. BofL messages signify that the FDDI interface is up
and functioning normally when there is no data traffic.
If the link becomes unavailable and both this parameter and the LLC Data Enable
parameter are enabled, the router disables the LLC interface after the time you
specify using the BofL Timeout parameter. When you set this parameter to
Disable, the router disables the LLC interface immediately after the link becomes
unavailable.
By default, BofL messages are enabled when you add the circuit. You can disable
and reenable BofL messages on an interface.
Setting the BofL Interval
The BofL interval is the amount of time the router waits before disabling the LLC
interface when the link becomes unavailable and BofL is enabled.
By default, the BofL interval is 5 seconds. You can change the interval of BofL
messages to a value from 1 to 60 seconds.
