Re: Auto Port Aggregation
This needs to be configured on the switch too and is only possible on one physical switch.
Most of the time you would use manual configuration with 2 links and no hot standby. This will use both lans balanced for outgoing traffic.
LAN Monitor is used when you want to setup a hot standby interface, which is only used when the other fails.
The configuration can be done with SAM - see the already mentioned APA manual.
My 2 cents,
Armin

Re: Auto Port Aggregation
One note. The above configurate was tested and we ran into isssues during boot that the aggregate would not form due to some time-out/delays during boot. We ultimately went to MANUAL (FEC) and all works well, with FEC you loose the management protocals ( i.e. no syslog or nettl entries when you loose a leg in the aggregate ).
If anyone has different experience please post as I will then reinvestigate.

Another Note: The NICs used must be able to support the same speed and duplex settings. i.e. cannot use a 10MB card and 100MB card set to auto as the switch will not allow the aggregate creation.
If anyone has different experience please post as I will then reinvestigate / revise my stand.

Re: Auto Port Aggregation
If IP is on the port and "ifconfig lan0 unplumb" doesn't work, what exactly is the command and error message you used ?
As for using 2 different switches for a load balancing aggregate, there are a couple of possibilities, but they really depend on the capabilities of the network eqipment, not on the HP software. 1) Cisco has a technology called "Stackwise" that allows stackable switches to be merged into a single backplane for redundancy. 2) Nortel has something similar called "SMLT" that has been tested with APA.
Otherwise, you should use Lan Monitor .
