How Do I Configure 802.1x Authentication on More Than One

Ethernet Port?

Once you configure 802.1x authentication on an interface, the LAN wizard will
no longer display any 802.1x options for Ethernet ports because Cisco SDM uses
the 802.1x configuration globally.
Note For configuring switches, the LAN wizard will continue to display the 802.1x
options.
If you want to edit the 802.lx authentication configuration on an Ethernet port, go
to Configure > Additional Tasks > 802.1x.
