HP Auto Port Aggregation (APA) Release Notes for HP-UX 11i v1, 11i v2, and 11i v3 March 2009
Table 1-1 Fixes in the HP APA B.11.11.30 Release (continued)
DescriptionDefect ID
The lanqueryconf command might put ports having VLANs configured on them
into failover groups. The lanapplyconf command fails if it detects these ports
inside a failover group.
CR: JAGag17374
SR: 8606461410
The lanapplyconf command cannot create failover groups whose member ports
have an MTU of 259 or less.
CR: JAGag17375
SR: 8606461411
The lanapplyconf command dumps core if the NODE_NAME value in the /etc/
lanmon/lanconfig.ascii file is different from the server's hostname.

While experiencing a large number of port state changes, HP APA might place LACP
ports in the wrong link aggregate.
CR: JAGag23067
SR: 8606467695
When ports in a LACP link aggregate experience many protocol events, they might
move to the wrong LACP link aggregate.
CR: JAGag23068
SR: 8606467696
System hangs after repeatedly starting and stopping PAgP or LACP on ports.CR: JAGag38447

Known Problems and Limitations
This section provides a list of known problems and limitations as known to HP at time of
publication. If workarounds are available, they are included.
• HP ProCurve Switches
When disabling Cisco's Fast Ether Channel protocol on the HP 9000 server, the HP ProCurve
switches block that particular port from further use.
Corrective Action: In order to use the network physical port on the HP 9000 server, physically
move the connection from the server to the switch to another non-Cisco Fast EtherChannel
port on the switch.
• Cisco Catalyst 5000 Switches
— Turning off Cisco's Fast Ether Channel protocol on one network physical port on the
HP 9000 server might cause the entire link aggregate (the port it is associated with) to
be deconfigured.
Corrective Action: Reconfigure the switch; do not include the port in the link aggregate
being configured. See the appropriate switch documentation for information on how
to reconfigure link aggregates.
The Catalyst 5000 switch only allows two- or four-port link aggregates. See the Cisco
Catalyst 5000 Configuration Guide for information about these limitations.
— When interfacing a HSC 100Base-TX or PCI 4–port 100Base-TX to a Cisco Catalyst 5000
switch (with firmware version 4.5(4)) and ports in Desirable Mode connected to an HP
server with ports running HP APA, the link aggregations might go up and down
repeatedly.
Corrective Action: Install patch PHNE_23465 or its superseding patch.
• 3Com SuperStack II Switches
To interoperate with the switch, disable the Trunk Control Message Protocol (TCMP) on all
of the ports that are being used with HP Integrity servers.
