A few days ago I upgraded my IOS from 12.4(6)T to 12.4(11)T1. I've not made any additional config changes other than implementing IPS v5. Since then I've noticed a change in reporting format (more detail) to the drop alerts (see attached syslog). In addition I've noticed that the FW is not reporting as many drops & the direction of the drops are primarily outbound(my IP > out, no ACL out is used) since the upgrade.
The syslog attachments shows FW drops alerts the different IOS's.
How anyone else noticed these changes? Can anyone comment if they have seen these changes.
