Looks like yet another example of mysteriously disappearing features... We have a couple of 28x1's, we have recently upgraded IOS from 12.4(3d) to 12.4(21) on some of them due to a couple of issues, and suddenly I can see:
rtr-site1#show access-lists compiled
Compiled ACLs unavailable
- and the router stopped recognizing the "access-list compiled" directive.
Now when I look at IOS reference, I see that it lists Turbo ACLs as "available on Cisco 7200, 7500 and 12000".
I tried different 12.4(21) feature sets, but still not available - while working fine on 12.4(3d).
Is there a reasonable explanation for this other than a marketing move - the likes of "iPhone VPN is only supported on Cisco PIX and ASA"?
