Hi all,
I was trying to config qos on 3550 interface
Match protocol is not supported for this interface
So does this mean that qos is not supported on 3550?
Thanks

3550s definately support QOS
You can match a protocol via an access list
Example
Here match TFTP traffic and set the dscp to AF21
!
access-list 150 permit udp any any eq 69
!
class-map match-any TFTP
match access-group 150
!
policy-map TFTP
class TFTP
set dscp af21
!
int fas 0/1
service-policy input TFTP
!

Hello Mahesh,
match protocol support means support of NBAR Network Based Application Recognition that is supported on SW based routers, and it is typically not supported on multi layer switches ( except C6500 with Sup32 PISA).
However, as noted by other colleagues, this does not mean that QoS is not supported at all on C3550
see QoS chapter on C3550 configuration guide
It supports the use of ACLs and the definition of class maps and policy maps that are the key components of modular QoS.
Hope to help

Hi Mahesh,
It supports Qos.
You can have the Qos monitoring and wrr-queue configurations on the interface. You can create MQC based Qos in the 3550. i.e. ACL-->Class-Map-->Policy Map-->Interface Service Policy.
Please do rate if the given information helps.
