Regarding the Sizing Capabilities of a WAE-512-1G Appliance, what is the meaning of the "Optimized TCP Connections" ?
Is this parameter related only from the initiated point ? or from both directions?
I'm asking this because, after instaling in inline configuration, a point-to-point circuit only, (2 WAE's + 1 CM), in the Branch WAE we had a Minor Alarm saying that we have reached the TFO Limitation, and on the ohter end, we haven't that alarm.
Most of the traffic(connections), should be from the Branch to the Central Site.
So, the main question is, if this parameter is related to from where the connection is initiated.
I am assuming that you are running 4.1.x version on WAEs. The 'show tfo detail' command will show you how many optimized TCP connections your h/w (WAE) supports. The 'show stat conn' will show you currently active optimized flows. If you see the currently active optimized flows equivalent to your WAE limit then you are expected to see that message.
It means that the number of TCP flows from branch office to central site are exceeding the what your device can support. So, you need a WAE that can support higher number of TCP connections.
