6500 IOS QoS for Multicast

[jradke]

Question Summary:

How do I set the p-bit (COS value) for multicast traffic ingressing on an interface?

Additional details:

1. Although I have had success matching all IP traffic ingressing from the encoder/streamer (multicast source) I want to match only multicast traffic.
2. I see no obvious reason why my attempts with ACL's for multicast are failing to match. Help!
3. I verified failing or work by output of policy-map information, wireshark from port mirror, and remote client receiving the multicast.

Traffic Type (Multicast):

Source IP: 10.0.0.1

Source Port: 1025

Destination IP: 239.100.0.5

Destination Port: 8208

Destination MAC: 01:00:5e:64:00:05

Here is my configuration:

class-map IPTV

match access-group <ATTEMPT X>

policy-map MARK_INBOUND_IPTV

  class IPTV

   set dscp cs4

interface GigabitEthernet3/9

service-policy input MARK_INBOUND_IPTV

Individually attempted the following ACL's for the match statement<ATTEMPT X>:

FAIL:

1. access-list 81 permit 224.0.0.0 15.255.255.255
2. access-list 4 permit 239.100.0.5
3. access-list 700 permit 0100.5e13.05b8 0000.00ff.ffff
4. access-list 700 permit 0100.5e00.0000 0000.00ff.ffff

SUCCESS: (inadequate because it is all IP traffic not just multicast)

1. access-list 7 permit any

Command output from Fails:

I found that matching on the destination port number works as well:

access-list 104 permit udp any any eq 8208 

sho policy-map int g3/9 input

GigabitEthernet3/9

  Service-policy input: MARK_INBOUND_IPTV

    class-map: IPTV (match-all)

      Match: access-group 104

      set dscp 32:

      Earl in slot 5 :

        64144752 bytes

        30 second offered rate 3980472 bps

        aggregate-forwarded 64144752 bytes

    Class-map: class-default (match-any)

      0 packets, 0 bytes

      30 second offered rate 0000 bps, drop rate 0000 bps

      Match: any

        0 packets, 0 bytes

        30 second rate 0 bps

I'd really like to match on all multicast though. The destination IP or MAC makes the most sense but they fail.

Success! Using this extended list to specify the multicast works as needed:

access-list 104 permit udp any 224.0.0.0 15.255.255.255

different from the ACL I found in a posting earlier which doesn't work:

access-list 81 permit 224.0.0.0 15.255.255.255
