Glossary Fast Ethernet firewall Flood engine flooding forwarding fragment fragmentation Fragment Reassembly Processor FTP FTP server full duplex FWSM Any of a number of 100-Mbps Ethernet specifications. Fast Ethernet offers a speed increase 10 times that of the 10BaseT Ethernet specification while preserving such qualities as frame format, MAC mechanisms, and MTU. Such similarities allow the use of existing 10BaseT applications and network management tools on Fast Ethernet networks. Based on an extension to the IEEE 802.3 specification. Router or access server, or several routers or access servers, designated as a buffer between any connected public networks and a private network. A firewall router uses access lists and other methods to ensure the security of the private network. Detects ICMP and UDP floods directed at hosts and networks. Traffic passing technique used by switches and bridges in which traffic received on an interface is sent out all the interfaces of that device except the interface on which the information was received originally. Process of sending a frame toward its ultimate destination by way of an internetworking device. Piece of a larger packet that has been broken down to smaller units. Process of breaking a packet into smaller units when transmitting over a network medium that cannot support the original size of the packet. A processor in the IPS. Reassembles fragmented IP datagrams. It is also responsible for normalization of IP fragments when the sensor is in inline mode. File Transfer Protocol. Application protocol, part of the TCP/IP protocol stack, used for transferring files between network nodes. FTP is defined in RFC 959. File Transfer Protocol server. A server that uses the FTP protocol for transferring files between network nodes. Capability for simultaneous data transmission between a sending station and a receiving station. Firewall Security Module. A module that can be installed in a Catalyst 6500 series switch. It uses the shun command to block. You can configure the FWSM in either single mode or multi-mode. G GBIC Gigabit Ethernet global correlation global correlation client GigaBit Interface Converter. Often refers to a fiber optic transceiver that adapts optical cabling to fiber interfaces. Fiber-ready switches and NICs generally provide GBIC and/or SFP slots. For more information, refer to the Catalyst Switch Cable, Connector, and AC Power Cord Guide. Standard for a high-speed Ethernet, approved by the IEEE (Institute of Electrical and Electronics Engineers) 802.3z standards committee in 1996. The IPS sensor shares information with other devices through a global correlation database to improve the combined efficacy of all devices. The software component of CollaborationApp that obtains and installs updates to the local global correlation databases.
