Displaying Network Login Settings

To display the network login settings, use the following command:
show netlogin info {ports <portlist> vlan <name>}
Example
#show netlogin info ports 9 vlan temporary
Port 9: VLAN: temporary
Port State: Not Authenticated
Temp IP: Unknown
DHCP: Not Enabled
User: Unknown MAC: Unknown
In this example, the user is using campus mode and no authentication has taken place. Therefore, the
port state displays as not authenticated. No packets sent by the user on port 9 will get past the port
