I am installing Cisco 3750x (stacked) Access switches and will be (cross-stack) trunking them to MLX4's. My question is in regards to QOS on the MLX side....I am trusting DSCP from the Avaya phones (Sig and Voice traffic) and want to preserve their markings across the MLX Core. Could someone please shoot me an MLX example config. I have an idea on what it needs to look like but want some validation if possible.
Thanks in Advance!!!!

Ok so here is the configuration I am going with on the MLX (v3.8) side.
qos-tos map cos-dscp 0 8 16 24 32 40 46 56
dscp decode-map COR_VOIP
dscp-value 40 to priority 5 drop-precedence 3
dscp-value 46 to priority 6 drop-precedence 3
dscp encode-map COR_VOIP
priority 5 drop-precedence 3 to dscp-value 40
priority 6 drop-precedence 3 to dscp-value 46
qos-tos trust dscp
Anyone see an issue with this config or do you see that I am missing anything from a Brocade perspective?
Thanks in advance!

Sorry for the delay, your config look ok to me, however I did notice you said the MLX is on ver 3.8 (current is 5.1 or 5.2 I think) - might be worth look at updating that.
Suggets you look at "Configuring Quality of Service for the NetIron XMR and NetIron MLX" chapter 14 Ver 4.1 (this is the oldest I have here) of The Configuration Guide- Page 511 (PDF page)
