we have some strange situation.
According to the documentation the GRE traffic on SUP720 should be processed in CEF mode. But If I look onto our graps I can clearly see that there is a dependency between amount of GRE traffic and management CPU load: GRE traffic is about 400Mbit and COPU load is about 20%.
I tried to "sniff" the traffic which is procesed by CPU (some strange "remote" command) but I don't see any reason why that traffic goes throug the CPU - it's not fragmented, the size of packets are less then tunnel MTU size.
Which traffic on SUP720 are not processed in CEF mode and sent to CPU?
