I have a 4240 inline between an ASA and a Switch, and am experiencing errors on the switch indicating receive discards.
The devices are directly connected like this, ASA --- IPS --- SWITCH. The ASA and Switch have the speed/duplex fixed to 100/Full, but the IPS is auto negotiate. Both ports have negotiated to 100/Half, which I believe is causing the issue (open to alternative suggestions) however if I change to fixed parameters I loose connectivity. How should these connections be configured to remove the errors?
