A

administrative key 

An integer value that determines which network physical ports can be aggregated into a common LACP link aggregate. The key must match the key of the desired aggregate that the user wants the port to join


aggregate 

A group. For APA, a group of up to eight ports (32 ports for LACP aggregates) makes one link aggregate. There can be 50 link aggregates per computer.


aggregation 

See aggregate.


APA 

Auto Port Aggregation


ARP 

Address Resolution Protocol. A TCP/IP protocol used to obtain a node's physical address.


Auto Port Aggregation 

APA. An HP software product that allows grouping up to eight ports into an aggregate to boost performance and provide port failover. The eight port limit applies only for FEC_AUTO and MANUAL mode.


F

failover group 

A logical grouping of one or more physical ports formed by LAN Monitor. The failover group is used as an alternative if the link fails.


Fast EtherChannel 

See FEC.


FEC 

See Fast EtherChannel. The proprietary name of Cisco's port aggregation product. When referring to FEC mode, it indicates use of PAgP on a link..


FEC_AUTO 

The automatic configuration mode of FEC.


flow 

A sequence of MAC frames between a pair of hosts where all of the MAC frames form part of the same conversation between that pair of hosts.


G

group capability 

An integer value used to determine which network physical ports can be aggregated into an FEC link aggregate.


H

Hot Standby 

A method of providing high availability


L

LACP_AUTO 

Link Aggregation Control Protocol


LAN 

Local Area Network


LB_IP 

Internet Protocol-based algorithm for server–to–router configurations.


LB_MAC 

MAC-based algorithm for server–to–switch configurations (this is the default algorithm).

See also “Preparing for Configuration” for information..


LB_PORT 

TCP/UDP port-based algorithm for server–to–server (back-to-back) configurations


link aggregate 

A logical grouping of one or more physical ports into a single fat-pipe. This term is used to describe LACP_AUTO, Manual, or PAgP (Cisco Fast EtherChannel) created logical ports.


link aggregation 

See link aggregate.


linkaggPPA 

The PPA or logical card instance number of a specific link aggregate.


load balancing 

A method of distributing traffic across the network physical ports in a link aggregate. Unicast and multicast traffic is distributed across the network physical ports in a link aggregate. Broadcast traffic is always sent out the first network physical port in a link aggregate


M

MAC 

Media Access Control


MANUAL 

The default mode of port configuration. Can be performed by using SMH (preferred) or by editing two configuration files.


MIB 

Management Information Base


N

network adapter 

A network device which has one or more network physical ports.


network physical port 

The communications channel formed when you attach a network cable between a specific network port (adapter card) and a LAN device.


P

PAgP 

See Port Aggregation Protocol.


PCI 

Peripheral Component Interconnect


physical point of attachment 

See PPA.


port 

The communications channel formed when you attach a network cable between a network physical port and a LAN device.


port aggregate 

See link aggregate.


port aggregation 

See link aggregate.


Port Aggregation Protocol (PAgP) 

The proprietary port aggregation protocol, developed by Cisco Systems Inc., which automatically determines a bidirectional connection between two network physical ports.


port priority 

An integer value used to determine which network physical port will be used as the port in a link aggregate in hot standby mode.


PPA 

A unique integer identifier for each network physical port installed on a server.


S

server–to–router 

See LB_IP.


server–to–server 

See LB_PORT.


server–to–switch 

See LB_MAC.


SMH

T

TCP 

Transmission Control Protocol


trunk 

See link aggregate.
