FMC filtering based on vlan

[eugmtx]

I need to prioritize UDP IPv4 packets with vlan say 4500 over all other ingress packets coming to a port of the Broadcom switch on P2041. I am new to this but have been looking at AN4760.pdf (Frame Manager Configuration Tool Example Configuration and Policy).

Questions:

1. How to specify vlan = 4500 in the policy file?
2. Is there an example I can use for the rest of the <distribution> entry to make sure that packets with vlan 4500 have a higher priority than the rest of the packets?

Alternatively, instead of vlan=4500 I can use the PCP field. The packets that I need to prioritize will have PCP=7 while all others will have the default value of zero.

Thank you in advance for any suggestions,

Eugene

For vlan=4500:

<key>

<fieldref name ="vlan.tci"/>

                </key>

                <entry>

                        <data>0x4500</data>

                        <mask>0xffff</mask>

                        <queue base="0xd00" count="1"/>

                </entry>

for pcp=7:

<key>

<fieldref name ="vlan.tci"/>

                </key>

                <entry>

                        <data>0xe000</data>

                        <mask>0xe000</mask>

                        <queue base="0xd00" count="1"/>

                </entry>
