it has the following configuration:

FEX04#sh int status | include 104/1/26
Eth104/1/26 DONGLE connected 300 full 100 --
FEX04#sh run int Eth104/1/26
interface Ethernet104/1/26
description DONGLE
switchport access vlan 300
spanning-tree port type edge
speed 100
FEX04#

What can we do to fix this issue ?
