In regards to question 1 - Does the entire 2.2.3 install fail or just the Postoffice update portion. If you already have the 2.2.1.1 version of the PO and everything installs correctly, you can safely ignore the PO update error message. The PO is already at the latest rev.

If the PO update failure is aborting the 2.2.3 install then try commenting out the following line in the 2.2.3 install script - '$FSNAME/idd-po-sol-sparc-2.2.1.1.bin install | tee -a $logFile'. You don't need to install it since you are already at the appropriate rev level.

As for the switch issue. You are correct that Cat IOS does not have the inpkts enable feature, and more importantly does not have the learning disable feature for the span/monitor port. I am not sure if Cat IOS does allow the Reset packets in from the monitor port. And if it does, then it is likely that the packets coming in will cause problemsd with the CAM tables, because we currently spoof both the source and destination mac addresses of the packets and these mac addresses would then wind up being mapped to the span/monitor port instead of the actual ports.

We are looking into addressing the mac address issue in a future release of the IDS appliance, but whether or not the switch allows packets in from a monitor port would have to be tested, or confirmed by someone more familiar with Cat IOS.
