configure netlogin dynamic-vlan uplink-ports

configure netlogin dynamic-vlan uplink-ports [port_list | none]


Specifies which port(s) are added as tagged, uplink ports to the dynamically created VLANs for network login.

Syntax Description

port_list Specifies one or more ports to add to the dynamically created VLAN for network login.
none Specifies that no ports are added. This is the default setting.


The default setting is none.

Usage Guidelines

Use this command to specify which port(s) are used as uplink ports and added to the dynamically created VLAN for network login. The uplink ports send traffic to and from the supplicants from the core of the network.

Uplink ports should not be configured for network login (network login is disabled on uplink ports). If you specify an uplink port with network login enabled, the configuration fails and the switch displays an error message similar to the following:

ERROR: The following ports have NetLogin enabled: 1, 2

If this occurs, select a port with network login disabled.

Enabling Dynamic Network Login VLANs

To configure the switch to dynamically create a VLAN upon receiving an authentication response, use the following command:

configure netlogin dynamic-vlan [disable | enable]

By default, the setting is disabled. For more detailed information about this command, see the usage guidelines configure netlogin dynamic-vlan uplink-ports.

Viewing Status Information

To display summary information about all of the VLANs on the switch, including any dynamic VLANs currently operating on the switch, use the following command:

show vlan

If the switch dynamically creates a VLAN, the VLAN name begins with SYS_NLD_ and the output contains a d flag for the dynamically created VLAN.

To display the status of dynamic VLAN configuration on the switch, use the following command:

show netlogin

The switch displays the current state of dynamic VLAN creation (enabled or disabled) and the uplink port(s) associated with the dynamic VLAN.


The following command configures the switch to add ports 1:1-1:2 to the dynamically created network login VLAN:

configure netlogin dynamic-vlan uplink-ports 1:1-1:2


This command was first available in ExtremeXOS 11.6.

Platform Availability

This command is available on ExtremeSwitching 5320, 5420, 5520, and 5720 series switches.
