Description (partial)

Symptom:
Customer does in fact have outputs on:

show cable flap-list
show cable modem flap

But not able to see this information via SNMP:

$ snmpwalk -v2c -c brcpublic 10.140.30.72 1.3.6.1.4.1.9.9.114.1.1.11                
SNMPv2-SMI::enterprises.9.9.114.1.1.11 = No Such Object available on this agent at this OID

Conditions:
The trigger condition is: for a slot, if the first Integrated-Cable interface is up, the flap entry will be empty.

For example

#show ip interface brief
