Module: RDN-CABLE-SPECTRUM-MIB
OID (symbolic): RDN-CABLE-SPECTRUM-MIB::flapCmMisses
OID (numeric): 1.3.6.1.4.1.4981.6.1.1.2.1.8
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of times the CMTS misses the Ranging request from the Cable Modem. The CMTS can check up to 16 consecutive times for a ranging request message during one polling cycle.
Misses are not desirable since this is usually an indication of a return path problem; however, having a small number of misses is normal.
Ideally, the Hit should be much greater than the Miss counts.
What is flapCmMisses?
Count of times the CMTS failed to receive an expected ranging request from this modem, checked up to 16 consecutive times per polling cycle. A small number of misses is normal, but a growing count usually points to a return-path (upstream RF) problem.
