Network Slowness

[ray_stone]

Hello Experts,

On one of our Prod site, users are reporting of slowness of network and now I need to investigate on router of which IP is chowking the bandwidth so please suggest the command to check the same & also would know the other steps to handle these such cases.

Thanks.

Thanks leolaohoo for your prompt response.

will the same commands be used on switch to investigation the situation. Any other suggestion to more troublesheet these such cases.

Thanks.

Will these commands show the output based on live sessions/IP. For an example, one of the ftp session is using most bandwidth which is still active and downloading is in progress so the commands will show the same IP which is being used for FTP or once the session gets over then only it will show the IP in output. Please confirm the same too. Thanks.

To show who are your top-talkers use the command "sh ip flow top".
