Management Information Base
Management Information Base (MIB) attributes are readable and writable across the Integrated
Local Management Interface (ILMI) through use of the Simple Network Management Protocol
(SNMP).
The one-port PA-T3 serial port adapter supports MIB-II (RFC 1213) and the DS3 interface MIB
(RFC 1407).
The two-port PA-2T3 serial port adapter supports MIB-II (RFC 1213) and the DS3 interface MIB
(RFC 1407).
