IPC-VERIFICATION-FAIL
Default Severity: Major (MJ), Non-Service-Affecting (NSA)
Logical Objects: NE
The Internal Patchcord Connection (IPC) Verification Fail condition occurs when the connection verification
detects a major problem in the internal patchcords that includes:
• A minimum of one patchcord is disconnected
• A minimum of one patchcord with insertion loss greater than the major degrade threshold (measured
loss is greater than 3 dBm).
1 dBm (degrade) and 3 dBm (fail) are the default threshold values, these are the NE default values and can
be changed in the range from 0 dBm to 20 dBm.

ISIS-ADJ-FAIL
Default Severity: Minor (MN), Non-Service-Affecting (NSA)
Logical Object: OCN
The Open System Interconnection (OSI) Intermediate System to Intermediate-System (IS-IS) Adjacency
Failure alarm is raised by an intermediate system (node routing IS Level 1 or Level 1 and 2) when no IS or
end system (ES) adjacency is established on a point-to-point subnet. The Intermediate-System Adjacency
Failure alarm is not supported by ES. It is also not raised by IS for disabled routers.
The alarm is typically caused by a misconfigured router manual area adjacency (MAA) address.
Clear the ISIS-ADJ-FAIL Alarm
