set pnc
set pnc lock | unlock
On critical-reliability systems (duplicated PNC),
set pnc lock locks the active port
network connectivity in the active state. PNC interchanges will be prevented, and
the active PNC will remain active regardless of its state of health. Duplicate call
setup will still take place, though the standby is not available for service. This
condition can also be initiated by the reset pnc interchange override-and-lock
command. You can tell if the PNC is locked by looking at the
Software
Locked?
field on the
status pnc screen. (The
Interchange Disabled?
field
refers to the antithrashing mechanism.)
Set pnc unlock releases the lock and enables subsequent interchanges to take
place.
If the health of the active pnc has degraded to worse than that of the standby pnc,
unlocking the active port network connectivity can cause an immediate PNC
interchange This condition can be foreseen by use of status pnc.
System restarts remove a PNC lock.
!
CAUTION:
If the active PNC experiences problems while in the locked state, service
disruptions may occur that would ordinarily be avoided by PNC interchange.
Parameters
