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.

Hot Standby A method of providing high availability

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
