HP UX Auto Port Aggregation (APA) Software manual Glossary, Administrative

Glossary

A
administrative	An integer value that determines which network physical ports can be aggregated into a common
key	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	APA. An HP software product that allows grouping up to eight ports into an aggregate to boost
Aggregation	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	See FEC.
EtherChannel
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–routerconfigurations.
LB_MAC	MAC-based algorithm for server–to–switchconfigurations (this is the default algorithm).
	See also 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
