Port on Summit X440-48t don't work o.k.

[Kar_Del_Moral]

It's more like weird issue, it first happen like a month ago, the user couldn't get IP address, was the only user on the switch, we change the patch cords, change the vlan to make short it was not a shortage of ip's on that segment (via DHCP), and then it work, but today happen again, even connecting directly to the switch with my laptop, at the end, I connect the user in a different port on the same switch (also tried without Auto option, no success) what do you suggest me to check?

Thanks

p.s. so far is the only user/port with this issue

Yes, we have seen were a port or group of ports on a switch would enter a weird state that kept them from learning mac addresses. As a result they could not forward traffic to the devices connected to them.

Best of luck,

Yes, I knew the mac, and couldn't find it... So I'll reported to TAC then, just as port in switch not working properly

[davidj_cogliane]

So you know the mac of the PC?
You searched the FDB for the mac and could not find it?

If the above are true I would call tac as I have seen that issue before.

No, because, when I try to check to which port was connected (without following the cable on the rack) I couldn't find it with the show fdb command
