reset interchange 

One of the following messages is displayed:

Command successfully completed

If the reset pnc interchange command is unsuccessful 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 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

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 health of the 
standby PNC is the same as or better than that of the active, no service 
disruption takes place; all stable calls and links are preserved. Some unstable 
calls may drop.

”interchange” (without a preceding hyphen) must be specified on 
the command line.

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.

!

This option forces execution of the interchange regardless of 
the state of health of the standby, possibly disrupting service.
