Hi, i'm am trying to use to following class-maps and policy maps on a Cisco 7600. The same maps have been used on both 3700 series and 7200 series. However when i try to apply IP_TO_MPLS_OUT and MPLS_TO_IP_IN on the 7600 (with SUP32 and 48 port gigabit blade) i get a message on the console
"set qos group" not supported.
I used the QoS group to carry the MPLS EXP value (as label would is popped) and this works well.
How can i get the QoS group to work on the 7600, if not is there a valid workaround?
Many thanks for your help.
policy-map IP_TO_MPLS_OUT
class qosgrp5
set mpls experimental topmost 5
priority percent 10
class qosgrp4
bandwidth remaining percent 50
set mpls experimental topmost 4
class qosgrp2
bandwidth remaining percent 20
set mpls experimental topmost 2
class class-default
bandwidth remaining percent 30
random-detect
set mpls experimental topmost 1
policy-map CE_OUT
class qosgrp5
set ip precedence 5
class qosgrp4
set ip precedence 4
class qosgrp2
set ip precedence 2
policy-map MPLS_TO_IP_IN
class MPLS_EXP5
set qos-group 5
class MPLS_EXP4
set qos-group 4
class MPLS_EXP2
set qos-group 2

Hi,
I'm not aware that you can use qos groups on c7600 (LAN ports ?).
For the MPLS_TO_IP direction you can use 'mpls propagate-cos' on the egress interface as workaround. This rewrites the egress IP ToS with the internal DSCP (which is inferred from the topmost MPLS label).
For the IP_TO_MPLS direction you could just match on the original DSCP ?
cheers,

The fact that 7600 see them as LAN ports (even in no switchport mode) is going to be a problem. If will mean priority etc can not be used.
Do you know if this would be any better with a SUP720 or SUPRSP720? I currently have a SUP32.
Thanks.
