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 Ethernet switch module with two or more interconnected LANs or WANs.
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.
M
MAC Address
Media Access Control Address. The MAC Address is a hardware specific address that identifies each network node.
MAC Address Learning
MAC Address Learning characterizes a learning bridge, in which the packet’s source MAC address is recorded. Packets destined for that address are forwarded only to the bridge interface on which that address is located. Packets addressed to unknown addresses are forwarded to every bridge interface. MAC Address Learning minimizes traffic on the attached LANs.
