cnfconprotect
cnfconprotect
To configure protection on a PVC, use the cnfconprotect command in the VoIP switching/trunking
operating mode.
cnfconprotect lcn protect-enable lock-state second-lcn
Syntax Description
Command Modes VoIP switching/trunking
Usage Guidelines You must use the addcon command to add the primary and secondary PVCs before using this command,
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 secondary channel fails, the connection 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.
Examples The following example shows that LCN 132 is protected and unlocked, and LCN 217 is the secondary
(fallback) LCN:
cnfconprotect 132 1 1 217
