Hi Rene, I have a strange problem related to your post. We have a unmananged switch connected to a managed switch port. That port is configured as follows:
description Conference Room
switchport access vlan 43
switchport mode access
switchport port-security maximum 16
switchport port-security
authentication host-mode multi-host
authentication port-control auto
dot1x pae authenticator
dot1x timeout quiet-period 20
dot1x timeout tx-period 10
spanning-tree bpduguard enable
If a user connects to this switch and then unplugs (not Logoff), goes to their desk and plugs in, their port is Err-disabled. I have to shut the port on the conference room and then shut and no shut their port. After that all is well. What can I do to prevent me having to shut the port the conference room unmanaged switch is in?
Thank you,
Kevin Martin
