Hello,
A client of mine wants to use private-VLAN ("isolated ports") on interfaces configured as IEEE 802.1X with MAB - but I am running into trouble with the switchport mode private-vlan host command: " Command rejected: Gi1/0/1 is Authentication. Authentication must be disabled before changing port mode enabled port."
Should it be possible to configure, or is there a limitation w/h the MAB feature?
IOS c3750-ipbasek9-mz.150-1.SE.bin
Thanks

Hi,
try adding this command globally first:
dot1x system-auth-control
and than try
switchport mode private-vlan host

Hi Reza,
The dot1x system-auth-control command is already there - I think it's needed for the IEEE802.1X feature.
I did remove the voice VLAN, but the problem remains.
Best ones,
Lennart
