HP Auto Port Aggregation Administrator's Guide HP-UX 11i v3 (766140-001, March 2014)

Aggregate Instance Number
The PPA number of the link aggregate or failover group. Enter a value. For example, use 900 for
lan900.
Mode
The configuration mode of the link aggregate or failover group. Your choice will be determined
by the capabilities of the link partner (for example, switch, router, or server) to which the link
aggregate physical interfaces will be connected. See your link partner's documentation to determine
which modes it supports. Check the mode you want to use. The following choices are available:
LACP_AUTO Automatically start LACP on the physical port.
FEC_AUTO Automatically start the FEC protocol on the physical port.
LAN_MONITOR The ports are used for a failover group.
Not_Enabled Create the link aggregate with the Key, Group Capability, or Load Distribution
Algorithm set to a non-default value, but without any ports. You must add ports
to enable it.
Failover Policy
The mechanism by which LAN Monitor chooses the active port in a failover group. The following
choices are available:
Priority Based If the active port fails, LAN Monitor chooses the standby link that is UP and
that has the highest port priority (highest value) to be the new active link.
Cost Based If the active port fails, LAN Monitor chooses the standby link that is UP and
has the lowest normalized port cost to be the new active link. This is also
called proactive failover. See “Proactive failover” (page 9) for a description
of proactive failover and “Proactive failover examples” (page 90) for
proactive failover examples.
Check the failover policy you want to use.
Instance Number
The PPA numbers of the ports to include in the link aggregation or failover group. Enter the numbers
on the sheet.
NOTE: Before adding ports to a failover group, you must check link connectivity between the
ports.
HW Path
The hardware path to the NIC associated with the port to include in the link aggregate or failover
group. A numeric string of hardware components, noted sequentially from the bus address to the
device address.
For link aggregates, this is a string in the form LinkAggxx, where xx is the last two digits of the
instance number (00 – 49).
This field is provided as a convenience in case you either do not know the PPA number of the port
or want a place to capture and save both values.
Interface Type
A short description of the NIC associated with the port. For example, I GB.
