Enabling Jumbo Frames in CISCO Switch

xtremaxteam · ‎03-31-2012

Hi,

I have tried to enable jumbo frames by:

Go to Port Management >> Port Settings
Enable Jumbo Frames. Click Apply.
Save configuration and reboot

After that I try to verify that jumbo frames is really working by looking at the Status and Statistics >> RMON >> Statistics.

It seems that the page only shows frame size of up to 1632 Bytes. Does this mean that the Jumbo Frames are not working? Is this the correct way to verify that Jumbo frames are enabled?

Thanks.

Hi,

This setting allows the frames to pass on the switch, nothing more. The rest of the devices needs to capable to send and receive such frames as well. You need to configure the NICs and possibly applications to do this.

Make sure all communicating devices are capable of jumbo frames. If you mix them you will have trouble.

For a sample how to do this on linux see

Hope this helps.
