Re: Ethernet jumbo frame support

Hi,

I doubt there is a linecard supporting jumbo frames with 9252 Bytes Ethernet payload. A list of supported MTU sizes for the various linecards can be found at:

http://www.cisco.com/en/US/products/hw/switches/ps663/products_tech_note09186a0080094713.shtml#jumbo

There is a table a bit further down on the page, where the link points to.

Note: The MTU size or packet size refers only to Ethernet payload.

Please be aware that as such you are using a different calculation method than the document. In any case the referenced document should answer your question.

Hope this helps! Please use the rating system.

Regards,

Martin

Re: Ethernet jumbo frame support

As per the docs, 9216 is supported. But the applications guys asking for 9252byte support. I cannot find any Ethe card supporing 9252 Byes in 6500.
