Deploying QoS to Cat4507 SUP 6-E

latintrpt
Level 1
Level 1

I was wondering if you guys can check out my config.  I haven't finished it all but I got a good start.

I'm confused about the ingress policy-map and where it should be applied.  Should it be applied to all the ports where the phones and PC's will be?

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

**-Conditionally Trust Port(s) (By default all ports are trusted)

int range gi1/1 - 48
qos trust device cisco-phone

int range gi2/1 - 48
qos trust device cisco-phone

int range gi5/1 - 48
qos trust device cisco-phone
exit

**-Classify traffic for QoS

ip access-list extended RTP
remark RTP (Real-time Transport Protocol) VIDEO CONFERENCING
permit udp 10.72.0.0 0.0.255.255 any range 16384 32767

Hi,

Cat 4507 + Sup6-E supports Per-port and Per-port/Per-vlan QOS policy.What you are configuring right now is that per-port policing and marking model, so you should apply this to all the ports.

With per-port/per-vlan HQOS model you have more granualrity to apply different QOS based on data and voice vlan. Depending upon your requirement, you can design that as well. Please see a medianet QOS campus design guide for more refrence :
