Conditions

When device connected to port comes up, wrong vlan is assigned and vlan config has to be re-apply Interface GigabitEthernet2/1 no dot1x timeout tx-period no source template DefaultWiredDot1xClosedAuth no dot1x max-reauth-req no switchport voice vlan no macro auto processing access-session inherit disable autoconf access-session inherit disable interface-template-sticky switchport access vlan 1059

Workaround

Reconfigure Vlan even if it is already present in running-config, i.e. interface GigabitEthernet2/1 switchport access vlan 1059
