This timer (in seconds) provides debounce functionality for an FDDI interface. When the FDDI ring becomes non-operational, the LLC interface will be disabled if the following conditions hold TRUE: 1. fddimibMACMAUnitdataEnable (contained in fddimibMACTable of rfc1512.mib) is enabled 2. This FDDI interface has been unavailable for wfFddiXLineCfgLossOfServiceTmo seconds. If the FDDI interface becomes enabled before wfFddiXLineCfgLossOfServiceTmo expires, then the timer is cancelled and nothing occurs. This debounce timer may be disabled by setting it to 0. In this case, when the FDDI interface becomes non-operational, the LLC interface will be notified right away.

Logical line number associated with this driver entity.

This attribute allows all FDDI Peer/Tree connections to reach the 'Thru' state. This is done to give the user some flexibility and allow them to Daisy Chain their Phy connections, mixing Tree & Peer connections. This type of daisy chaining DOES NOT conform to the SMT standard and is NOT recommended as it may result in a less than optimum token path. Normally when we have a Peer/Tree connection mix, we will wrap the connection, favoring PHY B. Enumeration: 'enable': 1, 'disable': 2.
