Known Problems and Limitations This section describes the known problems and limitations as known to HP at the time of publication. If workarounds are available, they are included. Known Problems with Switches • 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.
HP has tested switches from the following vendors to work with HP APA: • 3Com Corebuilder and SuperStack • All Cisco Catalyst series • HP ProCurve • Foundry • Alteon • Nortel • Extreme HP APA also supports Nortel's Split Multi-Link Trunking (SMLT) technology. Specifically, HP has tested the Passport 8006 and Passport 8010 switches with the version 3.7.13.0 of the software.

3 HP APA Overview for HP-UX 11i v3 This chapter provides information about the HP-UX 11i v3 (B.11.31.71) September 2012 release of HP Auto Port Aggregation (APA) and LAN Monitor software. Auto Port Aggregation HP APA is a software product that creates link aggregates, often called "trunks," which provide a logical grouping of two or more physical ports into a single "Fat-Pipe.
Problem: Inconsistent behavior while deleting aggregation onVM guest for DIO interface While deleting a DIO LACP aggregation in HPVM Guest for "iexgbe" driver a delay may be observed in deleting an aggregation. There is no loss of traffic, except some delay. This delay mostly attributes to two factors 1. Low number of vCPUs 2. lan reset taking time This issue is not very prominent if the number of interfaces in the aggregation is lower than the number of vCPUs.
Hardware Requirements This version of HP APA runs on HP Integrity servers with the HP-UX 11i v3 (B.11.31) operating system. HP APA supports Cisco's FastEtherChannel (FEC, also known as PAgP) protocol, the Link Aggregation Control Protocol (IEEE 802.3ad), or manual trunking mechanisms.
