Frequent ContributorHave you looked into https://www.intel.com/content/www/us/en/programmable/documentation/xgz1560360700260.html#tne1573761134640
on setting/checking the MTU size?
Occasional ContributorThank you for your continued attention.
We have found that some dpdk application can fully support giant frame and we ported the related functions to other applications. So far the issue with giant frame support has been resolved.
Frequent ContributorThank you for the update. Would you share with us what is the dpdk application and how you used it to support jumbo frames? I think it will be a good learning for all other forum users as well.
Occasional Contributorwell, It's my pleasure to help others.
1. DPDK L3fwd supports jumbo frames originally when you run it with '--enable-jumbo --max-pkt-len 9600 ';
2.the default mtu size of N3000-1(10G) is 1500, one should change it to 9600, and you can get the command by looking in the manual of ug-ias-n3000(chapter 8.1); the default mtu size of N3000-2(25G) is 9600, it have no need to be changed.
3. you can modify the mode of rx and tx to support jumbo frames by reference to l3fwd CMD_LINE_OPT_ENABLE_JUMBO_NUM module
For example, in the l2fwd application, you need to make the following changes
