| I have yet to take the QoS class so can someone give some advice:
I just these class maps:
class-map match-all WAN2LAN-VoIP-ctrl
match ip dscp af31
match ip dscp cs3
class-map match-all VoIP-ctrl
match ip dscp cs3
match ip dscp af31
match ip precedence 3
class-map match-all VoIP
match ip dscp ef
match ip precedence 5
class-map match-all WAN2LAN-VoIP
match ip dscp ef
is this correct or should I be using match-any.
Thanks in advance
Scott

| You should absolutely be doing a match-any.
The problem runs in when you have traffic marked CoS 3 and not DSCP 31
To be honest though, AF31 will have Precedence 3 as a part of it (you need
to break down the binary to see it).
The point here is that you want to prioritize your signalling traffic, which
can be CoS 3, Precedence 3 or DSCP AF31... since we want to match any of
them, we need to do a match-any.

| You want to use match-any. Match-all means the packet must match all
criteria defined in your map or it does not match. Match-any is any
single description in your maps. Currently, your signaling map does not
match any of the traffic you're trying to classify due to this behavior.
AF31 is bit structure 011010 and CS3 is 011000. There won't be a packet
that matches both. You want it to be an "either" statement, not an
"and" so use match-any. Also, if you use match-any, you can collapse
your class-maps for signaling into one map rather than two, which is
cleaner. Here is a collapsed map that works.
class-map match-any VoIP-ctrl
match ip dscp cs3
match ip dscp af31
match ip precedence 3
class-map match-any VoIP
match ip dscp ef
match ip precedence 5

are going for the CCIE Voice, make sure you know your QoS inside and

great book... It basically reads itself... the best cisco Press book I have
ever read (for downright usefulness the Configuring cisco CallManager and

But I still stand by statement that CoS is layer 2... and Precedence, aka

You are right, CS3 and Precedence 3 are the same thing... just different
ways of saying it.

| A question regarding the text written in this post.
The statement match-any on a 2950T, I guess it isn't possible to use, right?
c2950-i6q4l2-mz.121-22.EA1b.bin I use this image..

I was misreading it...
But I still stand by statement that CoS is layer 2... and Precedence, aka ToS is layer 3...
You are right, CS3 and Precedence 3 are the same thing... just different ways of saying it.

class-map match-any VoIP-ctrl

You want to use match-any. Match-all means the packet must match all criteria defined in your map or it does not match. Match-any is any single description in your maps. Currently, your signaling map does not match any of the traffic you're trying to classify due to this behavior. AF31 is bit structure 011010 and CS3 is 011000. There won't be a packet that matches both. You want it to be an "either" statement, not an "and" so use match-any. Also, if you use match-any, you can collapse your class-maps for signaling into one map rather than two, which is cleaner. Here is a collapsed map that works.
class-map match-any VoIP-ctrl
match ip dscp cs3
match ip dscp af31
match ip precedence 3
class-map match-any VoIP
match ip dscp ef
match ip precedence 5
..

I have yet to take the QoS class so can someone give some advice:
I just these class maps:
class-map match-all WAN2LAN-VoIP-ctrl
match ip dscp af31
match ip dscp cs3
class-map match-all VoIP-ctrl
match ip dscp cs3
match ip dscp af31
match ip precedence 3
class-map match-all VoIP
match ip dscp ef
match ip precedence 5
class-map match-all WAN2LAN-VoIP
match ip dscp ef
is this correct or should I be using match-any.
Thanks in advance
Scott
