Delivered as an option with the AS5800, major enhancements to the Cisco System Controller include the Expression MIB, Health Monitor and Bulk Transfer MIB . These simple network management protocol ( SNMP ) extensions allow the network operator to monitor an entire POP of dial ports with a minimum of polling and network traffic.

The database is hierarchical ( tree-structured ) and each entry is addressed through an RFCs discuss MIBs, notably RFC 1155, " Structure and Identification of Management Information for TCP / IP based internets ", and its two companions, RFC 1213, " Management Information Base for Network Management of TCP / IP-based internets ", and RFC 1157, " A Simple Network Management Protocol ".

While the total amount of UDP traffic found on a typical network is often in the order of only a few percent, numerous key applications use UDP, including the Domain Name System ( DNS ), the simple network management protocol ( SNMP ), the Dynamic Host Configuration Protocol ( DHCP ) and the Routing Information Protocol ( RIP ), to name just a few.

Another IP Encapsulating Security Payload ( ESP ) was researched at the Naval Research Laboratory as part of a DARPA-sponsored research project, with openly published by IETF SIPP Working Group drafted in December 1993 as a security extension for SIPP . This AH ) is derived partially from previous IETF standards work for authentication of the Simple Network Management Protocol ( SNMP ) version 2.

The IETF developed the Simple Network Management Protocol ( SNMP ) in the late 1980s and it proved to be a very popular network management BER-encoded SNMP . In addition, many equipment vendors did not provide the option to completely configure their devices via SNMP . As operators generally liked to write scripts to help manage their boxes, they found the CLI lacking in a number of ways.
