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

In previous versions of HP APA, the port
must have IP address configured and
must be the highest priority or lowest
cost. In the HP-UX 11i v3 version of HP
APA, you can assign the port any priority
or cost values. You also need not
configure an IP address on it.
HP recommends that you always assign
the port the highest priority or the lowest
cost in a failover group.
STANDBY Specifies a standby port for the
FAILOVER_GROUP. A standby port is a
port that replaces the active port when
the active is incapable of carrying traffic.
Specify this keyword only if the failover
group has more than one port. A failover
group must have one or more standby
ports.
Both the PRIMARY and STANDBY keywords have the following
fields:
• The LAN interface name (for example, lan0 and lan1).
• The port priority that will be assigned to the port. The port
with the highest priority is the active port.
• A cost value for the LAN interface preceded by a colon (:).
This is an optional field. See “Proactive failover” (p. 9) for
more information.
POLLING_INTERVAL The number of microseconds between polling messages. You
can specify this keyword multiple times in the configuration file.
A link aggregate's polling interval is set to the last specified
interval. For a description of this parameter, see “Failover group
advanced parameters” (page 27).
DEAD_COUNT The number of polling packets that are missed before LAN
Monitor sends a nettl log message to the user that indicates
the link might have problems and the network should be checked.
For a description of this parameter, see “Failover group
advanced parameters” (page 27).
LM_RAPID_ARP Enables (on) or disables (off) the ability to transmit gratuitous
ARP messages at intervals shorter than 5 seconds. By default,
LM_RAPID_ARP is off. For a description of this parameter, see
“Failover group advanced parameters” (page 27).
LM_RAPID_ARP_INTERVAL The number of microseconds between rapid gratuitous ARP
messages. If the value is out of the valid range and
LM_RAPID_ARP is on, the interval value last processed with the
lanapplyconf command is used. If LM_RAPID_ARP is off,
this value is ignored for the corresponding failover group. For
a description of this parameter, see “Failover group advanced
parameters” (page 27).
LM_RAPID_ARP_COUNT The number of gratuitous ARP packets sent rapidly. If the value
is not in the valid range and LM_RAPID_ARP is on, the count
value last processed with the lanapplyconf is used. If
LM_RAPID_ARP is off, this value is ignored for the corresponding
failover group. For a description of this parameter, see “Failover
group advanced parameters” (page 27).
