• Supports IPv6 addressing for link aggregates and LAN Monitor failover groups. You can now use port-based (LB_PORT) and IP-based (LB_IP) load balancing for IPv6 traffic on link aggregates. In addition, you can configure an IPv6 address on the primary port of a failover group. • Supports HP-UX APA operations in the System Management Homepage (SMH) Graphical User Interface and Terminal User Interface. • Supports HP-UX APA operations in the new nwmgr command.
3 Known Problems This section can be divided into two parts as follows: • “Known Problems with this release” (page 10) • “Known Problems with Switches” (page 10) Known Problems with this release This section provides a list of known problems and limitations as known to HP at the time of publication. If workarounds are available, they are included.
Corrective Action: 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.
