ISATAP

Intra-Site Automatic Tunnel Addressing Protocol .

ISATAP is an automatic overlay tunneling mechanism that uses the underlying IPv4 network as a non- broadcast/multicast access link layer for IPv6. ISATAP is designed for transporting IPv6 packets within a site where a native IPv6 infrastructure is not yet available.

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.

LLDP-MED

Link Layer Discovery Protocol - Media Endpoint Discovery. LLDP allows network managers to troubleshoot and enhance network management by discovering and maintaining network topologies over multi-vendor environments. MED increases network flexibility by allowing different IP systems to co- exist on a single network LLDP.

Load Balancing

Enables the even distribution of data or processing packets across available network resources. For example, load balancing may distribute the incoming packets evenly to all servers, or redirect the packets to the next available server.

M

MAC Address

Media Access Control Address. The MAC Address is a hardware specific address that identifies each network node.
