A couple of Rate-Limit questions

[mohammedmahmoud]

Dear All,

Regarding the rate-limit command, i've got a couple of questions:

- Does the rate-limit command depend on a certain IOS or platform?

- Is there a solution to prevent the rate-limit from dropping packets when exceeding?

Thanks in advance.

Hi,

-rate-limit seems to be supported from IOS11.1 but I am not sure. So yes, it is IOS.dependent

-you must configure the 'exceed-action'and not necessarily 'drop' but 'transmit' or 'continue' are also possible statements.

Hope this helps!

Hey thanks,

But can you please help me understanding the jop of "trasmit" and "continue: keywords.

Drop --> drops any traffic exceeding the rate limit.

Continue --> scans another rate limit. (what shall it do if there is no other rate limit ?)

trasmit --> trasmit packets. (if it will transmit any excess packet so what is its role ?)

thanks in advance.

Hi,

If you have a 'continue' statement and no other statement to follow, I think that the packet will be transmitted.(I think there is an implicit transmit at the end, not sure though!)

Otherwise :

You can 'transmit' 3 types of packets :

-complying with the basic throughput

-exceeding basic throughput but not exceeding the peak throughput

-violating all thresholds! If you transmit in this case, you can just remove the whole thing!

Correct me if i am wrong:

If i choose to "tramsit" then there is no need for the whole command !

If you choose "transit" for confirm-action, exceed-action and violate-action, then yes!
