How to mark DSCP values on inbound packets on a Brocade Fastiron SX running Layer 2 Code


Global Config
enable acl-per-port-per-vlan ==> Requires a reboot

traffic-policy <name=QOS> count

ip access-list extended 101
remark RTP-ACL
permit udp 192.168.1.0 0.0.0.255 192.168.1.0 0.0.0.255 range 16384 32767 dscp-marking <DSCP #> dscp-cos-mapping traffic-policy QOS
remark VOICE-CONTROL-ACL
permit tcp 192.168.1.0 0.0.0.255 192.168.1.0 0.0.0.255 range 2000 2002 dscp-marking <DSCP #> dscp-cos-mapping traffic-policy QOS
remark EVERYTHING-ELSE
permit ip any any dscp-marking 0 dscp-cos-mapping traffic-policy QOS

interface ethernet 1/1
ip access-group 101 IN

***You will need to write an ACL that works for your network and your needs. Make sure you have permit ip any any at the end***

dscp-marking = Mark the packet with the DSCP Value
dscp-cos-mapping = Use the internal mappings to map DSCP to COS values
traffic-policy = Allows you to see some counters on the ACL (Not very helpfull)
