Usage Guidelines You must use the addcon command to add the primary and secondary PVCs b efore us ing thi s comm and,
and ensure that both channels have the same peak-cell-rate argument value.
Protect the primary channel using the cnfconprotect command and configure the secondary (fallback)
LCN.
The primary channel can be locked so that it is inoperative and forces a switchover to the secondary
channel. If the primary channel is locked and the se conda r y cha nn el fa ils, th e co nnec tion fails.
If the primary PVC is protected, automatic switchover to a specified secondary PVC occurs if a primary
PVC fails.
A protected channel cannot be deleted. To delete the channel, use the cnfconprotect command to
unprotect the primary channel, delete the secondary channel, and then delete the primary channel.
