A management information base (MIB) is a database used for managing the entities in a communication network.Most often associated with the Simple Network Management Protocol (SNMP), the term is also used more generically in contexts such as in OSI/ISO Network management model.
The Cisco Supervisor Engine serves as the management card for modular Cisco switches that can also, in some cases, act as forwarding/routing element. [1]Over time, the Supervisor Engine has undergone multiple iterations and was different for different modular switches in Cisco Portfolio (Catalyst 4000, 4500, 5000, 5500, 6000, 6500, 9400, 9600 and Nexus switches).
Net-SNMP is housed on SourceForge and is usually in the top 100 projects in the SourceForge ranking system. It was the March 2005 SourceForge Project of the Month. [1] It is very widely distributed and comes included with many operating systems including most distributions of Linux, FreeBSD, OpenBSD, Solaris, and OS X.
Cisco's IOS software maintains one IDB for each hardware interface in a particular Cisco switch or router and one IDB for each subinterface. The number of IDBs present in a system varies with the Cisco hardware platform type. Physical and logical interfaces on the switch will be referenced with either expanded or abbreviated port description names.
In computing, the Structure of Management Information (SMI), an adapted subset of ASN.1, is a technical language used in definitions of Simple Network Management Protocol (SNMP) and its extensions to define sets ("modules") of related managed objects in a Management Information Base (MIB).
IOS XE is a release train of Cisco Systems' widely deployed Internetworking Operating System (IOS), introduced with the ASR 1000 series. [2]It is built on Linux [3] [4] and provides a distributed software architecture that moves many operating system responsibilities out of the IOS process [5] [6] and has a copy of IOS running as a separate process.
