To switch to the redundant port for a VLL SAP from an L2 access interface properties form

Prerequisites
CAUTION 

CAUTION

Service Disruption

Nokia recommends that you set the OLC state of a service to Maintenance before you switch to a redundant port or channel. See the NSP System Administrator Guide for more information.

Then reset the port to the previous state after the switch is complete.

Perform this procedure from a port properties form when port redundancy is configured on one or more a Cpipe or Epipe SAPs to:

  • switch to the backup port or channel assigned to the SAP, for example, in the event of a fault on the primary port or channel

  • switch back to the primary port or channel assigned to the SAP, for example, after a fault condition on the primary is cleared

Note: When multiple SAPs are selected, switching is attempted only for the SAPs that support port redundancy and on which port redundancy is properly configured.

Port redundancy switching fails if the SAP or port is included in one of the following redundancy objects:

  • BGP-MH

  • MC-APS

  • MC-LAG

  • MC-ring

Steps
 
1 

Choose Manage→Service→Services from the NFM-P main menu. The Manage Services form opens.

2 

Choose a VLL and click Properties. The VLL_type Service (Edit) form opens.

3 

On the navigation tree, expand Site→L2 Access Interfaces→L2 access interface→SAP, right-click on SAP and choose Properties. The Port (Edit) form opens.

4 

Click on the Port tab.

5 

Click Switch to Redundant SAP. A dialog box appears.

6 

Click OK. The Port (Edit) form closes and a dialog box appears indicating that the SAP object on the current site is removed.

7 

Click OK.

8 

Verify the following:

  • For on-node switching, the SAP is deleted from the primary port, and a new SAP is created on the site.

  • For off-node switching, the SAP and the parent site are deleted, and a new site, SAP, and spoke SDP bindings are created for the service.

9 

Choose the SAP in the navigation tree. The Port (Edit) form opens.

10 

Click on the Port tab. The Manual Switch Backup State indicator displays one of the following:

  • Backup SAP in Use, if you switch from primary to backup

  • Backup Port Specified, if you switch from backup to primary

Note: When the Manual Switch Backup State indicator reads Backup SAP in Use, the displayed port redundancy information is for the primary port of the SAP, and is read-only.

Close the forms.
