Hello, dear friend.
The force-switch command is used to control the protection switch on a protection group. When you need to perform a forced switch on a protection group, run this command. After this command is executed, the forced switch is performed regardless of the status of the specified target member.
The undo force-switch command is used to cancel a forced switch. Running this command clears the forced switch operation on a protection group that is under a forced switch. In addition, a message is displayed to indicate that the command is incorrect if the PG is not under a forced switch.
Usage Guidelines
Run the config command to enter global config mode, and then run the protect-group(mode) command to enter protect-group mode.
The priority of a forced switch is:
Lower than the priority of a lock operation. The lock operation on a member in a protection group cancels the forced switch operation on the member.
Higher than the priority of a manual switch. If a manual switch command is executed and then the forced switch operation is performed, the result of the forced switch prevails.
Higher than the priority of failure signals. Therefore, the forced switch is performed regardless of the status of the specified target member.
A forced switch operation cannot be performed on a protection group when it is disabled.
When a protection group is enabled, a forced switch operation cannot be performed on the protection group after the protection group is frozen.
A forced switch operation cannot be performed on a protection group when it is locked.
A dual-homing protection group has only one member, which is also called a local port.
When a local port is switched to a peer port, set the parameters for the local port and use peer-group-member to specify the peer port when running this command.
When a peer port is switched to a local port, use peer-group-member to specify the local port and set the parameters for the peer port when running this command.
Thanks.
