We notice massive "out discards" on several ports. 71G and 71K Series.<BR /> I have the same question as Zdenek.<BR /> <BR /> What does cause an "out discard"?<BR /> TXQ overflow? Port buffer overflow?<BR /> <BR /> Thanks and regards<BR /> Alex<BR /> Fri, 05 May 2017 18:17:00 GMT https://community.extremenetworks.com/t5/extremeswitching-other/what-does-cause-the-out-discard/m-p/9683#M711 aloeffle 2017-05-05T18:17:00Z https://community.extremenetworks.com/t5/extremeswitching-other/what-does-cause-the-out-discard/m-p/9684#M712 Hi.<BR /> <BR /> <A href="https://gtacknowledge.extremenetworks.com/articles/Solution/S-Series-Invalid-out-discard-errors-reported-on-Lag-ports" target="_blank" rel="nofollow noreferrer noopener">https://gtacknowledge.extremenetworks.com/articles/Solution/S-Series-Invalid-out-discard-errors-repo...</A><BR /> <BR /> <A href="https://gtacknowledge.extremenetworks.com/articles/Solution/Out-discards-incrementing-on-routed-links" target="_blank" rel="nofollow noreferrer noopener">https://gtacknowledge.extremenetworks.com/articles/Solution/Out-discards-incrementing-on-routed-link...</A><BR /> <BR /> <A href="https://supportforums.adtran.com/docs/DOC-6490" target="_blank" rel="nofollow noreferrer noopener">https://supportforums.adtran.com/docs/DOC-6490</A><BR /> <BR /> I would suggest you look at the ‘show port flowcontrol’ counters.
