Re: ip-precedence AND . dscp-bit based queuing at the same time
It's Ok to mix dscp and precedence if you're careful. Remember that Precedence only looks at the first three bits of eight in TOS field while DSCP looks at six bits. (from the left)
This means that Precedence 0=DSCP 0-7. Precedence 1=DSCP 8-15. etc... It also means that DSCP=8 will match Precedence=1. As will DSCP=9 and DSCP=10... all the way up to DSCP 15 will match Precedence=1 .
Therefore, you must call the class-maps defining your DSCP values before the class-maps calling Precedence values in your policy-maps. The policy-map evaluates the class-maps in order. Also, don't define DSCP values for traffic that coincide with precedence values. In otherwords, don't use values 0,8,16,24,32,40,48, or 56 for any DSCP definitions.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
