APA Configuration

[OBSUV0091126257]

We have the following configuration :

=> hardware : C7000 enclosure with HP virtual connect (flexten)
Blade BL860c i2 running HP-UX 11.31

We used HP-UX APA (aggregation) with virtual interfaces (lan0 & lan1) provided by the virtual connect manager and the enclosure. The enclosure itself is connected to external switch with VLAN tagging => cisco WS-C3750X-48

We encounter some issues (severe packet loss) when both interfaces are in use. If one interface is taken offline everything runs fine. If both interface are taken online at the same time => packet loss occurs

Do you have some clues and/or best practices to configure HP-UX APA with the above configuration (C7000 + flexten, etc) ? Thank you.
