Cisco Systems 15600 Manual De Usuario

The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms 
do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. 
Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's 
path protection feature, which may be used in any topological network configuration. Cisco does not 
recommend using its path protection feature in any particular topological network configuration.

In node view, click the Maintenance > Protection tabs. 

In the Protection Group area, select the protection group with the port you want to switch. 

In the Selected Group area, each port is identified as Working or Protect. Each port also has a status: 

Active—The port is carrying traffic.

Standby—The port is not carrying traffic.

[MANUAL TO WORKING]—A Manual switch has moved traffic to the working port. 

[MANUAL TO PROTECT]—A Manual switch has moved traffic to the protect port. 

[FORCE TO WORKING]—A Force switch has moved traffic to the working port. 

[FORCE TO PROTECT]—A Force switch has moved traffic to the protect port. 

The normal status is for one port to be Working/Active and the other to be Protect/Standby.

In the Selected Group area, select the port that you want to switch. For example, if you want to switch 
traffic from the working port to the protect port, click the working port.

Click Force.

This task applies the Force external switching command to a 1+1 
protection scheme.
