I am using 3750 24-ports ethernet switch and need to configure QoS but not succeded.
I am using c3750me-i5-mz.122-25.SEG1.bin IOS.
I am not able to configure below command-
service-policy output|input <policy name>
Please let us know for any further information required & please help me.
Thanks for your reply,but I am getting follwoing errors while implementing QoS under fast ethernet-
SW(config-if)#service-policy output QoS
Feb 17 08:46:55: cqm_check_service_policy: Assigning a policy to output side of an unsupported interface
SW(config-if)#service-policy input QoS
Bandwidthis only supported in a hierarchical policy on ES interfaces
PLEASE HELP ME OUT!!!JITENDRA
Most small L3 switches don't support the same QoS features as the small routers. The ME3750 also supports different features based on type of port. It appears from your messages, what you're trying to do isn't supported.
I need to know which QOS policy is supported by 3750ME switch.
As i have already posted my requirements that we want to execute QOS on fast ethernet ports as well as Gig ports, kindly suggest will the above mentioned policy will work for the same or NOT.
I also want to know the supported policy commands on ME3750 switch.
Kindly help me out.
The reference I provided, along with the reference manual, would explain best the QoS features available on the ME3750.
My understanding, though, is the ME3750's FE ports don't support the QoS features of the (ES) gig ports.
If the device doesn't offer the features you need, beyond using a different device or doing without, sometimes newer IOS versions add features. So besides reading the QoS capabilities of your installed IOS, you might want to review release notes and/or read the QoS sections of the latest IOS for the platform. (Many features in these platforms are very dependent on the hardware, so enhancements, if any, tend to be minor.)
we are not clear with above statement,
does Gig Ports of 3750ME will support QoS or we need to verify IOS which support QoS.
As per our analysis, current IOS feature set is-
METRO C3750 EMI IMAGE
& QoS feature supported are with it-
-Modular QoS CLI (MQC)
-MPLS Quality of Service (QoS) Enhancements
-QoS Packet Marking
Could i deploy prev mentioned QoS Policy with current having above mentioned feature set.
OR suggest me to go which IOS?
I haven't worked with a 3750 Metro switch, but from the information in my reference, and QoS.txt you posted to Giuseppe, it appears there's a good chance the ES ports would accept your policy.
What you're trying to do, I believe, could also be accomplished on a non-ES port, much as it would be done on a "normal" 3750. However, how it's done is totally different.
If I'm reading the documentation correctly, SVI related QoS seems to be only for non-ES ports. For ES ports, it appears you would apply the policy to the interface.
in which configuration context are you trying to give the command ?
An SVI, a physical interface, an ES port ?
how is the configuration of the policy map it includes QoS hierarchy ?
see for your platform and IOS version
there are differences depending on the type of interface and the type of policy-map used
I think you need to give
before being able to use QoS commands as in other switch platforms
Hope to help
