Hi guys,
i have this Cisco 12406 with IOS Version 12.0(32. Im using rate-limit on the interface and its seems its not working.
Is there a bug on this ?

Hello Jeff,
on what type of linecard have you tried to configure the command ?
in 12406 what you can do is linecard dependent : don't expect to be able to use QoS features on 3GE engine 2 linecard for example.
You can do it in old 1GE engine1 linecards or 4GE engine3 linecards (that support modular QoS).
Hope to help

Hi Giuseppe ,
Slot 2 type = 3 Port Gigabit Ethernet
state = IOS RUN Line Card Enabled
How can i verify the engine?
Thanks.

Hello Jeff,
use
execute-on slot 2 sh ver
however, it is the 3GE engine2 linecard for sure and it is a backbone linecard with no QoS features.
or sh gsr
Hope to help

Hi Giuseppe,
Using thise rate-limit input 140000000 96000 96000 conform-action transmit exceed-action drop will give a output of 5 minute input rate 156677000.
It is working but a little tweak maybe.
What do you think?

Hello Jeff,
I admit that I was remenbering wrong.
the 3GE should support a subset of functionalities of real CAR that is called PIRC (Per Interface Rate Control)
probably you cannot use an ACL to define traffic to be rate-limited.
And I think you cannot use on subifs.
We had a customer using them so marking was done on C7500 edge routers.
I was not able to have it working in some lab setups but I had collegues able to.
I apologize.
Have you used sh int rate-limit ?
Best Regards

Hi Giuseppe,
Here's the output. I dont know if this will be stable. Using rate limit of different value and attaining a different output.
Input
matches: all traffic
params: 138000000 bps, 96000 limit, 96000 extended limit
conformed 5991343 packets, 3542M bytes; action: transmit
exceeded 346155 packets, 349285916 bytes; action: drop
last packet: 1ms ago, current burst: 0 bytes
last cleared 00:03:25 ago, conformed 137971200 bps, exceeded 13603595 bps
Thanks a lot.
