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, and reset it to the previous state after the switch is complete. See the NSP System Administrator Guide for more information.

Perform this procedure from a service or site 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 port or channel 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
