Guys,

I have a few questions related to the APA product.

On a LAN_MONITOR mode,

a) What is the default fall back policy ? Is that a configurable parameter ?

b) Is there a command by which I can forcefully promote a lan adapter to be active ?

:- If it is, it will be easy to schedule my switch outages.

Regards,

Kaps

Okie, I have been doing a lot of tests with APA in LAN_MONITOR mode. I could not locate any APA commands that can do this. But I can technically do them with the following options.

a) The default fallback policy is "NO". i.e. When I pulled the cable on the primary adapter, the secondary became primary. When I put the cable back onto the primary, nothing happened. It did not fallback.

b) I could not locate a APA command to do this. But technically I could do think of the following and I tested it , It works.

1. Restart APA with a different configuration
2. Reset the primary PPA with lanadmin -r command. It initiates a failover and the next adapter becomes the primary.

Please share your thoughts.

Regards,

Kaps

Hey Kaps,

I also did a lot of testing on this also and it does not go back to your primary until your fail over network is disconnected or reset. I know this is not much help but it confirms what you are seeing. You could use lanadmin to do a reset of your fail over this would force it to go back to your primary card.

I did not do testing on this but can't you delete the primairy port, after the connection is back, from the APA-conf
with; â ¢ lanadmin -X -d "portnumber" 900

The secundairy would become primairy and after this add the port to the APA-conf;
â ¢ lanadmin -X -a "portnumber" 900
