Dear group member!
I tried to find the exact description of qos-preclassify command on CCO, but I
could not.
Here is an explanation I could extract:
If I have a main interface that:
- has service-policy output based on L4 pclassification,
- it is a GRE/IPSec tunnel endpoint, no native traffic is passing through,
then the serice-policy has no effect, as the outgoing packets are allready
encapsulated into tunnels, so L4 filter does not match..
Applying qos pre-classify on main interface case that the service-policy is
applied on output packets before encapsulation.
My questions:
- Do I think right?
- Is it possible to implement queuing on main interface this way, or only
marking will work?
- Is DSCP copied to GRE/IPSEC tunnel header automatically with or without
using qos pre-classify?
Thanks,
Gabor
