Managing Faults on Virtual Services Platform 7200 Series and 8000 Series Version 5.1.2

link-state
advertisement (LSA)
Packets that contain state information about directly connected links
(interfaces) and adjacencies. Each Open Shortest Path First (OSPF) router
generates the packets.
Logical Link Control
(LLC)
A protocol used in LANs to transmit protocol data units between two end
stations. This LLC layer addresses and arbitrates data exchange between
two endpoints.
mask A bit string that the device uses along with an IP address to indicate the
number of leading bits in the address that correspond with the network part.
media A substance that transmits data between ports; usually fiber optic cables or
category 5 unshielded twisted pair (UTP) copper wires.
Media Access
Control (MAC)
Arbitrates access to and from a shared medium.
MultiLink Trunking
(MLT)
A method of link aggregation that uses multiple Ethernet trunks aggregated
to provide a single logical trunk. A multilink trunk provides the combined
bandwidth of multiple links and the physical layer protection against the
failure of a single link.
port
A physical interface that transmits and receives data.
quality of service
(QoS)
QoS features reserve resources in a congested network, allowing you to
configure a higher priority for certain devices. For example, you can
configure a higher priority for IP deskphones, which need a fixed bit rate
and split the remaining bandwidth between data connections if calls in the
network are more important than the file transfers.
Random Access
Memory (RAM)
Memory into which you can write and read data. A solid state memory
device used for transient memory stores. You can enter and retrieve
information from storage position.
Remote Network
Monitoring (RMON)
Creates and displays alarms for user-defined events, gathers cumulative
statistics for Ethernet interfaces, and tracks statistical history for Ethernet
interfaces.
reverse path
checking (RPC)
Prevents packet forwarding for incoming IP packets with incorrect or forged
(spoofed) IP addresses.
Routing Information
Protocol (RIP)
A distance vector protocol in the IP suite, used by IP network-layer protocol,
that enables routers in the same AS to exchange routing information by
means of periodic updates. You often use RIP as a very simple interior
gateway protocol (IGP) within small networks.
shortest path first
(SPF)
A class of routing protocols that use Djikstra's algorithm to compute the
shortest path through a network, according to specified metrics, for efficient
transmission of packet data.
