Change the bandwidth on cisco switch

[farhanullah776683998]

How can I configure if a customer asked to changed its bandwidth from 2 MB to 4 MB?

if you did not limit this in the first place, then you do not need change anything

Thank you Pieterh, Can you illustrate with command lines?

hi  farhanullah

please look at this document

SUMMARY STEPS
1. enable

2. configure terminal

3. policy-map policy-map-name

4. class[class-name|class-default]

5. bandwidth [bandwidth-kbps|remainingpercentpercentage|percentpercentage]

6. interface typenumber [name-tag]

7. service-policy {input|output}policy-map-name

8. end

Generally, wherever/however 2 MB is being enforced, change it to 4 MB.

Thanks Joseph W. Doherty, but I want to know how should I do with command lines?

[Joseph W. Doherty]

Assuming 2 MB is being enforce now, generally the command line is much like the line being used now, again, with a 2 MB value changed to 4 MB value. Also depending on how the 2 MB is configured, there might be additional command lines to get to the proper "mode" to apply the replacement commands, and perhaps a command line, couple, to get out of that mode.

If there's nothing in place that actually enforces the 2 MB now, we would need to know much more about your topology and platform. Logically bandwidth enforcement is done via policing or shaping, but how that's accomplished, or even supported, can vary much between platforms.

Hi there,

Joseph and I give you the same advice
1) look in the current configuration for the statement that is limiting the  bandwith to 2Mb
    you find an example in my other post to your question
2) change this statement to limit 4Mb

if no such statement is present,  you do not need to change anything on this switch
-> need to look for other limiting factors
a) the interface itself has bandwith limitations e.g. a 3G/HSDPA mobile network card -> change to 4G/5G network card
b) the provider for the external link limits the available bandwith
   -> ask you provider to increase the bandwith
