Question about CEF - Cat65xx - IOS

Hi Group,

I just want to clarify something about CEF on the Supervisor 1 and 2A

For my understand on the SUP1 there is no CEF supportet this means all routet packets are going through the routing engine..and also is possible I can see with ip accounting all packets...

When I use SUP2 with enabled CEF (which is supported) only the first routed packet are going through the routing engine and the following packets are switched !? So this means I don't see ALL packets in this flow with "ip accounting" !?

Can anyone clarify this ? Is this right ?

thx dennis
