This turns on or off actual enforcement of the four-entry access list configured via cdmipAccessIpAddress1 through 4. The MIB's own description warns that enabling this before adding the managing station's own IP address to the list will lock that manager out of the modem entirely, a real risk unique to this object since it is the single switch that activates all four address slots at once. An admin who sets this to enforced(1) without first confirming their own NMS address is in one of the four slots would immediately lose SNMP, Web, and Telnet access to the unit and need local console access to undo it.
