• Full Duplex must be used only for connections thru a SWITCH or POINT to POINT
connections. In particular you can use Full Duplex for 2 nodes interconnect using
crossed cable RJ45/RJ45 MI CBLG161.
When using Full Duplex, collision detection is disabled.
Switch ports should be configured with Auto–negotiation Enabled, except if you have
HACMP problems like "network_down" or "swap_adapter" where Auto–negotiation must be
Disabled Auto–negotiation introduces several seconds delays in case of connection or IP
address takeover which can perturbate HACMP heartbeats mechanism.
To configure Ethernet adapter speed:
23.Use
# smit chgenet
24.Select an adapter and change the parameter.
25.Adapter CONNECTOR
...
26.Apply change to DATABASE only [yes]
27.Reboot the system.
