Configuring 802.1x Authentication
This example shows how to configure the VLAN groups, to map the VLANs to the groups, to and verify
the VLAN group configurations and mapping to the specified VLANs:
Switch(config)# vlan group eng-dept vlan-list 10
switch(config)# show vlan group group-name eng-dept
Group Name Vlans Mapped
------------- --------------
eng-dept 10
switch# show dot1x vlan-group all
Group Name Vlans Mapped
------------- --------------
eng-dept 10
hr-dept 20
This example shows how to add a VLAN to an existing VLAN group and to verify that the VLAN was
added:
switch(config)# vlan group eng-dept vlan-list 30
switch(config)# show vlan group eng-dept
Group Name Vlans Mapped
------------- --------------
eng-dept 10,30
This example shows how to remove a VLAN from a VLAN group:
switch# no vlan group eng-dept vlan-list 10
This example shows that when all the VLANs are cleared from a VLAN group, the VLAN group is
cleared:
switch(config)# no vlan group eng-dept vlan-list 30
Vlan 30 is successfully cleared from vlan group eng-dept.
switch(config)# show vlan group group-name eng-dept
This example shows how to clear all the VLAN groups:
switch(config)# no vlan group end-dept vlan-list all
switch(config)# show vlan-group all
