Hi All,
I'm investigating an issue in our network where we get some packet loss accross our Man link. The Man is formed by two interfaces in each switch forming a etherchannel set to LACP in active mode.
I noticed that SWE2-1 has one interface media 10/100/1000BaseTX and the other 1000BaseLX SFP. I believe this is not an issue but happy to hear your experience with that.
Question: MTU Jumbo size don't match. is this an issue? Sorry I have not found enough information about tha yet hence I am here...
Thank you very much for your help.
Regards,
Fabio
