Management Information Base (MIB)
An acronym for Management Information Base. It is a set of database objects that contains information about a specific device.
Multicast Switching
A process whereby the switch filters incoming multicast frames for services no attached host has registered for, or forwards
them to all ports contained within the designated multicast VLAN group.
Open Shortest Path First (OSPF)
OSPF is a link state routing protocol that functions better over a larger network such as the Internet, as opposed to distance
vector routing protocols such as RIP. It includes features such as unlimited hop count, authentication of routing updates, and
Variable Length Subnet Masks (VLSM).
Out-of-Band Management
Management of the network from a station not attached to the network.
Port Mirroring
A method whereby data on a target port is mirrored to a monitor port for troubleshooting with a logic analyzer or RMON probe.
This allows data on the target port to be studied unobtrusively.
Port Trunk
Defines a network link aggregation and trunking method which specifies how to create a single high-speed logical link that
combines several lower-speed physical links.
Remote Monitoring (RMON)
RMON provides comprehensive network monitoring capabilities. It eliminates the polling required in standard SNMP, and can
set alarms on a variety of traffic conditions, including specific error types.
Routing Information Protocol (RIP)
The RIP protocol attempts to find the shortest route to another device by minimizing the distance vector, or hop count, which
serves as a rough estimate of transmission cost. RIP-2 is a compatible upgrade to RIP. It adds useful capabilities for subnet
routing, authentication, and multicast transmissions.
Simple Network Management Protocol (SNMP)
The application protocol offering network management services in the Internet suite of protocols.
