Good point. I missed the match-any key word.
It appears to not be working the way the command reference states.
With the match-any key word, it is supposed to match one or more of the
match criteria. The default is match-all.

Are you familiar with Bolean Logic and how it relates to class maps?
Your first class map, the packet would need to match af41 AND cs4 AND af42
AND cs6 which would be impossible.
Your second class map, the packet only needs af41 OR cs4 OR af42 OR cs6.

Dear all,
Can somebody expalin me about bellow two class-map configs need to perform
same or different functions ? Policy-map is applied on on egress of a WAN
link.
1. class-map match-any MM-LOW
match ip dscp af41
match ip dscp cs4
match ip dscp af42
match ip dscp cs6
With this config there is no matches on this class map and all goes through
default-class see the out put bellow , I get confirmed with access list
there are packets comming with dscp cs6.
Class-map: MM-LOW (match-any)
0 packets, 0 bytes
30 second offered rate 0 bps, drop rate 0 bps
Match: ip dscp af41 (34)
0 packets, 0 bytes
30 second rate 0 bps
Match: ip dscp cs4 (32)
0 packets, 0 bytes
30 second rate 0 bps
Match: ip dscp af42 (36)
0 packets, 0 bytes
30 second rate 0 bps
Match: ip dscp cs6 (48)
0 packets, 0 bytes
30 second rate 0 bps
Queueing
Output Queue: Conversation 137
Bandwidth remaining 40 (%)Max Threshold 64 (packets)
(pkts matched/bytes matched) 0/0
(depth/total drops/no-buffer drops) 0/0/0
2. class-map match-any MM-LOW
match ip dscp cs4 af41 af42 cs6
When I configure the class-map in this way it matches the packet. see the
out put bellow,
Class-map: MM-LOW (match-any)
187 packets, 168760 bytes
30 second offered rate 22000 bps, drop rate 0 bps
Match: ip dscp cs4 (32) af41 (34) af42 (36) cs6 (48)
0 packets, 0 bytes
30 second rate 0 bps
Queueing
Output Queue: Conversation 137
Bandwidth remaining 40 (%)Max Threshold 64 (packets)
(pkts matched/bytes matched) 0/0
(depth/total drops/no-buffer drops) 0/0/0
Best Regards
