One of the following messages is displayed:
Command successfully completed
If the reset pnc interchang e command is unsucc essful due to the state of health
of the standby Port Network Connectivity, operation of anti-thrashing, or the
following message will be displayed:
Interchange of pnc failed;
try again using the ’override-and-lock’ identifier
See the preceding c aution regarding use of the overrid e-and-lock option. If the
reset pnc interchange c ommand is unsucc essful due to a busyout of the stand by
PNC, the following message will be d isplayed:
Must release port network connectivity first
reset pnc interchange [override-and-lock]
NOTE:
This command does not work like other reset c ommands. Instead of
resetting or initializing hardware, a PNC interch ange is executed. Before
entering this command, lo ok at the states of health of the two PNCs with
status pnc.
This command executes a PNC interchang e on a Critical Reliability system
(duplicated PNC). The standby PNC becomes active and assumes control of
active call proc essing, and the active g oes to standby. If the health of the
standby PNC is the same as or better than that o f the active, no service
disruption takes plac e; all stable calls and links are preserved. Some unstable
calls may drop.
interchange ”interchange” (without a preceding hyphen) must be spec ified on
the command line.
override-and-lock This option is also used to override the an ti-thrashing mechanism.
Subsequent PNC interchanges are p revented, regardless of
changes in the states health of the PNCs. Double call setup still
takes place; each c all is set up on both PNCs. To unlock the PNCs,
use set pnc unlock.
!CAUTION:
This option forces execution of the interc hange regardless of the state of health of the standby, possib ly disrupting s ervice.
