Issue 1 May 2002

The output below for the last screen of this command shows bearer fault detection
links (BFDLs). These links exist only for port networks with IPSIs.
Field Descriptions
Location
The physical location of the far endpoint associated with the system link
(cabinet-carrier-slot-circuit).
Link
Type/Channel
The type of system-link and the processor channel number of the link (if there
is one). System links include the following (see ‘‘SYS-LINK (System Links)’’
on page 8-1533):
Expansion Archangel Links (EAL), Indirect Neighbor Links (INL), Processor
Gate Control links (PGC), PRI signaling links (PRI), System Port links (SAP),
Remote Neighbor links (RNL), Local Neighbor links (LNL). Processor channel
numbers range from 1 to 128.
State
Whether the system link is “up” or “down.”
Current Path
This field specifies the status of the current path. This field displays “none” if
the link is down or “present” if the current path is functional.
Faulted Path
This field shows whether the link has experienced a fault and been switched to
another path. “Present” indicates that the link has been faulted at least once.
“None” is displayed if the link has not gone down. “Default” is displayed if the
default faulted path is being used.
Last Fault
Recorded
The date and time that the most recent fault on the link took place.
