Re: trouble configuring two ethernet adapters AIX 5.2

well, is the network adapter configured at the right
speed? full-duplex?, is the network port active and
configured on the right vlan?

best regards,
Enrique.

Sorry, no help here but it looks like you having the

I haven't had time to try and look at this in any
more detail but the systems are exactly the same.

Hi,

I am having problems configuring two Ethernet
adapters. When I configure
the second adapter I lose some connectivity with the
first adapter. When
I down and detach the second adapter my connectivity
returns. There are
some static routes.

Any ideas? Thanks.
