Qos does not work

[blemignot]

hello,

I use a Nexus 93180YC-FX for our fiber optic customers and I would like to apply a policy on each port of my fiber optic customers in order to limit their connection speeds to the internet.
I use 7 different policies:
- Bandwidth limitation to 10 mpbs

- Bandwidth limitation to 20 mpbs
- Bandwidth limitation to 30 mpbs
- Bandwidth limitation to 40 mpbs
- Bandwidth limitation to 50 mpbs
- Bandwidth limitation to 100 mpbs
- Bandwidth limitation to 200 mpbs

Currently as I am in the test phase, I have created a lab on which my nexus is connected to the internet through an ASA5506 firewall.

When there is no policy on the nexus the connexion speed to internet is 120Mbps for download and 10Mbps for upload.

I see that when I put a policy of 10 or 50 or 100 Mbps on one port, it is applied correctly. The speedtest is indeed identical to the policy set up on port.

However the problem I encounter is only when I apply a policy different from the previous one on a second port.

For example I apply a policy of 10 mbps on the first port and another policy of 40 mbps on a second port.
Well during my speed test the speed on the two ports is only 10 mbps.

I am attaching you my configuration and I hope to be able to find a solution to this problem because I therefore need to apply different policies on my ports.

Thank you in advance for your advice.

Best regards

Benoît

Hello,

what if you change the class to class-default (which effectively does the same thing as matching ip any any) ?

policy-map type qos 10Mo
class class-default
police cir 10 mbps bc 200 ms pir 12 mbps be 200 ms conform transmit exceed drop violate drop
policy-map type qos 20Mo
class class-default
police cir 20 mbps bc 200 ms pir 22 mbps be 200 ms conform transmit exceed drop violate drop
policy-map type qos 30Mo
class class-default
police cir 30 mbps bc 200 ms pir 32 mbps be 200 ms conform transmit exceed drop violate drop
policy-map type qos 40Mo
class class-default
police cir 40 mbps bc 200 ms pir 42 mbps be 200 ms conform transmit exceed drop violate drop
policy-map type qos 50Mo
class class-default
police cir 50 mbps bc 200 ms pir 52 mbps be 200 ms conform transmit exceed drop violate drop
policy-map type qos 100Mo
class class-default
police cir 100 mbps bc 200 ms pir 102 mbps be 200 ms conform transmit exceed drop violate drop
policy-map type qos 200Mo
class class-default
police cir 200 mbps bc 200 ms pir 202 mbps be 200 ms conform transmit exceed drop violate drop

hi Georg,

I have experienced the exact same operation when i apply the class default on ports.

Best regards.
