IEEE Institute of Electrical and Electronics Engineers. An Engineering organization that develops communications and networking standards. IEEE 802.1d Used in the Spanning Tree Protocol, IEEE 802.1d supports MAC bridging to avoid network loops. IEEE 802.1p Prioritizes network traffic at the data-link/MAC sublayer. IEEE 802.1Q Defines the operation of VLAN Bridges that permit the definition, operation, and administration of VLANs within Bridged LAN infrastructures. Image File The system image is saved in a Flash sector called image. Ingress Port Ports on which network traffic is received. IP Internet Protocol. Specifies the format of packets and there addressing method. IP addresses packets and forwards the packets to the correct port. IP Address Internet Protocol Address. A unique address assigned to a network device with two or more interconnected LANs or WANs. IPX Internetwork Packet Exchange. Transmits connectionless communications. J Jumbo Frames Enables transporting the identical data in fewer frames. Jumbo Frames reduce overhead, lower processing time, and ensures fewer interrupts. L LAG Link Aggregated Group. Aggregates ports or VLANs into a single virtual port or VLAN. For more information on LAGs, see Defining LAG Membership. LAN Local Area Networks. A network contained within a single room, building, campus or other limited geographical area. Layer 2 Data Link Layer or MAC Layer. Contains the physical address of a client or server station. Layer 2 processing is faster than Layer 3 processing because there is less information to process.Layer 4 Establishes a connections and ensures that all data arrives to their destination. Packets inspected at the Layer 4 level are analyzed and forwarding decisions based on their applications. Glossary 177
