DOWNSTREAM NEIGHBOR
MAC address of the downstream neighbor, if known.
DUPLICATE ADDRESS FLAG
Summary output of the duplicate address test algorithm.
FRAME STRIP MODE
Current frame stripping mode of the MAC.
SA MATCH - Source address match mode of the frame stripping
algorithm matches the source address of the frame
with the MAC's MyLongAddress MLA, and if a match
is found, the frame is removed from the token ring.
FCI STRIP - The FCIS mode counts the number of frames
transmitted since the reception of a token, and
strips equal number of frames.
LOOPBACK
This is true if the link has been set up to receive frames
transmitted by it. This allows loopback testing either on the
ring or with one of the PHY port loopback modes.
NEGOTIATED TRT
Negotiated token rotation timer.
OLD DOWNSTREAM NEIGHBOR
Previous value of the downstream neighbor.
OLD UPSTREAM NEIGHBOR
Previous value of the upstream neighbor.
RING ERROR REASON
Reason code for the most recent link error.
DIRECTED BEACON RECEIVED - Link received particular beacon data.
DUPLICATE ADDRESS DETECTED - Duplicate address algorithm detected a
duplicate address.
DUPLICATE TOKEN DETECTED - A duplicate token was detected on the
ring.
FCI STRIP ERROR - Frame content independent strip
operation was terminated by the
receipt of a token.
NO ERROR - No errors have occurred on this ring.
PC TRACE INITIATED - PC-trace was initiated by this link.
PC TRACE RECEIVED - PC-trace was initiated by some other
link.
RING BEACONING INITIATED - Ring beaconing process was initiated by
this link. This process in initiated as
a result of serious ring failure, such
as loss of signal or jabbering station
transmitting in violation of the
protocol. This indicates to other
links on the LAN that corrective action
may be required.
RING INIT INITIATED - Ring initialization was initiated by
this link to initialize the ring and
create a token.
RING INIT RECEIVED - Ring initialization was initiated by
some other link to initialize the ring
and create a token.
RING OP OSCILLATION - Ring state has been continually changing
from operational to initializing.
RING PURGE ERROR - Link received a token while performing a
ring purge operation.
RING LATENCY
Current ring latency as measured by this link entity.
RING PURGER STATE
State of the ring purger election process.
CANDIDATE - The Link's Ring Purger process is participating in the
Ring Purger election algorithm as a candidate to become
the Ring Purger.
NONPURGER - The Link's Ring Purger process is in an idle state
listening for periodic Purger Hello frames.
OFF - The Link's Ring Purger process is disabled.
PURGER - The Link's Ring Purger process is performing the
function of removing no owner frames and duplicate
token from the ring. In this state, the process
transmits periodic Purger Hello frames.
STATE
State of the link entity.
BROKEN - Attempt to turn the link on failed the
initialization test, or link was on, but
failure was detected.
OFF-READY - FDDI Data Link communication services are not
available.
ON-RING INIT - Physical layer service is available and the
link entity enabled.
ON-RING RUN - Link detected that the Ring Initialization has
been successfully completed and the ring is
operational.
OFF-FAULT RECOVERY - State entered when a link entity detects
conditions that indicate faulty ring.
UPSTREAM NEIGHBOR ADDRESS
MAC address of the upstream neighbor, if known.
UPSTREAM NEIGHBOR DUPLICATE ADDRESS FLAG
Upstream neighbor's reported result of its duplicate address test.
