reset pnc interchange
Issue 1 May 2002
7-257555-233-143
Parameters
Output
One of the following messages is displayed:
Command successfully completed
If the reset pnc interchange command is unsuccessful due to the standby PNC’s
state of health (operation of anti-thrashing), the following message will be
displayed:
Interchange of pnc failed;
try again using the ’override-and-lock’ identifier
See the preceding caution regarding use of the override-and-lock option. If the
reset pnc interchange command is unsuccessful due to a busyout of the standby
PNC, the following message will be displayed:
Must release port network connectivity first
reset pnc interchange [override-and-lock]
NOTE:
This command does not work like other reset commands. Instead of
resetting or initializing hardware, a PNC interchange is executed. Before
entering this command, look at the states of health of the two PNCs with
status pnc.
This command executes a PNC interchange on a critical-reliability system
(duplicated PNC). The standby PNC becomes active and assumes control of
active call processing, and the active goes to standby. If the standby PNC’s
health is equal to or better than the active PNC’s, no service disruption takes
place; all stable calls and links are preserved. Some unstable calls may drop.
interchange ”interchange” (without a preceding hyphen) must be specified on the
command line.
override-and-lock This option is also used to override the anti-thrashing mechanism.
Subsequent PNC interchanges are prevented, regardless of changes in the
states health of the PNCs. Double call setup still takes place; each call is set
up on both PNCs. To unlock the PNCs, use set pnc unlock.
!
CAUTION:
This option forces execution of the interchange regardless of
the standby’s state of health, possibly disrupting service.
