New features in B.11.31.02 release
The B.11.31.02 version of HP APA:
• Supports the TSO (TCP Segmentation Offload), also known as Large Send, feature if an
aggregate is created with Ethernet cards that all support TSO or if the active port in a failover
group supports TSO.
• Supports 64-bit MIB (RFC 2863) statistics if all the interfaces within a link aggregation or
failover group support 64-bit statistics.
• Supports proactive failover for failover groups.
Proactive failover is a cost-based failover policy in which each port in a failover group is
assigned a cost. With this policy, the active port of a failover group is always the link that is
the most efficient at carrying traffic. Efficiency is measured in terms of normalized port cost,
which is the assigned port cost divided by the port's current link speed. The lower the
normalized port cost, the higher the efficiency.
• Supports the creation of Virtual LANs (VLANs) over link aggregates and failover groups.
• Supports the aggregation of up to eight physical ports into a MANUAL or FEC_AUTO mode
link aggregate.
For proper operation, the link partner (switch or server) must also be configured to create a
trunk using same mode on those ports that are connected to the physical ports of the link
aggregate. LACP_AUTO and LAN_MONITOR modes continue to support up to 32 ports into
a link aggregate or failover group.
• 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.
• Supports SSHA (Single System High Availability) Online-Deletion of NICs. Improves system
and network availability.
• Supports LACP (IEEE802.3ad) fast timeout.
HP APA can detect link failures more quickly.
• Supports Nortel's Split Multi-Link Trunking (SMLT) technology.
A link aggregate can span over more than one switch, which removes switches as a single
point of failure.
• Supports failover groups for use with HP Serviceguard.
• Supports the logging of status messages to thesyslog.log file.
