2.7.339 RING-ID-MIS
An RFI VT Layer condition occurs when the ONS 15454 detects an RFI in the SONET overhead because
of a fault in another node. Resolving the fault in the adjoining node clears the RFI-V condition in the
reporting node. RFI-V indicates that an upstream failure has occurred at the VT layer.
Clear the RFI-V Condition
Verify that the connectors are securely fastened and connected to the correct slot. For more information,
Step 1
refer to the "Install Cards and Fiber-Optic Cable" chapter in the Cisco ONS 15454 Procedure Guide.

2.7.339 RING-ID-MIS
The Ring ID Mismatch condition refers to the ring ID in APC. It occurs when a ring name does not match
other detectable node ring names, and can cause problems with applications that require data exchange
with APC. This alarm is similar to the
to BLSDR ring protection, RING-ID-MIS applies to DWDM node discovery within the same network.

view.
Click the Provisioning > Line tabs.
Verify that the Admin State column lists the port as IS. If the Admin State column lists the port as
OOS,MT or OOS,DSBLD, click the column and choose IS. Click Apply.
If ports managed into IS admin state are not receiving signals, the LOS alarm is either raised
