cdxCmtsCmChOverRowStatus
Cisco DOCSIS Cmts Cable Modem Channel Over Row Status
1.3.6.1.4.1.9.9.116.1.3.5.1.8
The status of this table entry. This value for cdxCmtsCmChOverMacAddress must be valid Mac address currently in the CMTS in order for the row status to be set to active successfully. Once the row status becomes active and state becomes waitToSendMessage, the entry cannot not be changed except to delete the entry by setting the row status to destroy(6) and since the operation cannot be stopped, the destroy(6) will just cause the SNMP agent to hide the entry from application and the SNMP agent will delete the entry right after the operation is completed.
