Hi, I want to prioritize voice traffic which comes in on Gig0/2.30 (marked with ToS 5 (184)) and reserve a bandwidth for it of 5 Mbps (class PREMIUM priority 5000)on tag-switching interface Gig0/1.
Now sh int gig0/1 mpls-exp shows:
GigabitEthernet0/1
Input
Exp Value 0: 38 packets, 3256 bytes
Exp Value 5: 1000 packets, 1522000 bytes
Output
Exp Value 0: 38 packets, 3104 bytes
Exp Value 5: 1000 packets, 1518000 bytes
sh policymap int gig0/1 shows:
GigabitEthernet0/1
Service-policy output: QOS-OUT
Class-map: PREMIUM (match-all)
1000 packets, 1518000 bytes
5 minute offered rate 37000 bps, drop rate 0 bps
Match: mpls experimental topmost 5
Queueing
Strict Priority
Output Queue: Conversation 264
Bandwidth 5000 (kbps) Burst 125000 (Bytes)
(pkts matched/bytes matched) 0/0
(total drops/bytes drops) 0/0
It seems for me that this works, but I expected to see
(pkts matched/bytes matched) 1000/1518000 in stead of 0/0 !?
Does anyone know if this policy-map is working or not ?
Best regards,
Peter

Hello Peter,
a detailed explanation of all counters can be found in "Understanding Packet Counters in show policy-map interface Output"
http://www.cisco.com/en/US/tech/tk543/tk760/technologies_tech_note09186a0080108e2d.shtml
In brief: the counter does not increase, if you have no congestion and the packets are CEF switched. Basically it counts the amount of packets in the L3 queueing system matching the specific class. No congestion means no packets in L3 queueing system, thus (pkts matched/bytes matched) 0/0
Hope this helps! Please rate all posts.
