Cisco 7609 with QOS Pre-Classify

Unanswered Question
Jan 4th, 2010

I have noticed in the 7609 with IOS of c7600s72033-advipservices-mz.122-33.SRC4.bin that the "QOS Pre-Classify" command is missing as a option off the GRE tunnels. How does the 7609 handle DSCP values when it encapsulations a packet before it send it on a GRE tunnel that might have QOS configured on the exit interface?

I have this problem too.

Hi Josh,

qos-preclassify is not supported on the c7600 / c6500 platforms... DSCP is copied from the original packet to the encapsulated packet.
