When you change the netlogin port’s mode of operation, the switch deletes all currently known
supplicants from the port and restores all VLANs associated with that port to their original state. In
addition, by selecting
mac-based-vlans, you are unable to manually add or delete untagged VLANs
from this port. Netlogin now controls these VLANs.
With netlogin MAC-based operation, every authenticated client has an additional FDB flag that
indicates a translation MAC address. If the supplicant’s requested VLAN does not exist on the port, the
switch adds the requested VLAN.
Displaying Netlogin MAC-Based VLAN Information
The following commands display important information for netlogin MAC-based VLANs.
FDB Information. To view FDB entries, use the following command:
show fdb netlogin [all | mac-based-vlans]
By specifying netlogin, you see only FDB entries related to netlogin or netlogin MAC-based VLANs.
The flags associated with netlogin include:
● v—Indicates the FDB entry was added because the port is part of a MAC-Based virtual port/VLAN
combination.
● n—Indicates the FDB entry was added by network login.
VLAN and Port Information. To view the VLANs that netlogin adds temporarily in MAC-based mode, use
the following command:
show ports <port_list> information detail
By specifying information and detail, the output displays the temporarily added VLANs in netlogin
MAC-based mode. To confirm this, review the following output of this command:
● VLAN cfg—The term MAC-based appears next to the tag number.
● Netlogin port mode—This output was added to display the port mode of operation. Mac based
appears and the network login port mode of operation.
To view information about the ports that are temporarily added in MAC-based mode for netlogin, due
to discovered MAC addresses, use the following command:
show vlan detail
By specifying detail, the output displays detailed information including the ports associated with the
VLAN. The flags associated with netlogin include:
● a—Indicates an authenticated network login port.
● u—Indicates an unauthenticated network login port.
● m—Indicates that the netlogin port operates in MAC-based mode.
Netlogin MAC-Based VLAN Example
The following example configures the netlogin MAC-based VLAN feature:
create vlan users12
create vlan nlvlan
configure netlogin vlan nlvlan
enable netlogin mac
