configure netlogin ports mode

Description

Configures the network login port‘s mode of operation.

Syntax Description

Default

The default setting is port-based-vlans.

Usage Guidelines

Use this command to configure network login MAC-based VLANs on a network login port.

If you modify the mode of operation to mac-based-vlans and later disable all network login protocols on that port, the mode of operation automatically returns to port-based-vlans.

When you change the network login 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. Network login now controls these VLANs.

With network login 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.

Configuration of port-based-vlans is lost if ONEPolicy is enabled.

Important Rules and Restrictions

This section summarizes the rules and restrictions for configuring network login MAC-based VLANs:

• If you attempt to configure the port‘s mode of operation before enabling network login, the switch displays an error message similar to the following:
  

  ERROR: The following ports do not have NetLogin enabled; 1

  To enable network login on the switch, use the following command to enable network login and to specify an authentication method (for example, 802.1X—identified as dot1.x in the CLI):

  enable netlogin dot1x

  To enable network login on the ports, use the following command to enable network login and to specify an authentication method (for example, 802.1X—identified as dot1.x in the CLI):

  enable netlogin ports 1:1 dot1x

• On ExtremeXOS versions prior to 12.0 on switches other than the ExtremeSwitching series switches, 10 Gigabit Ethernet ports such as those on the uplink ports on the switches do not support network login MAC-based VLANs.

  If you attempt to configure network login MAC-based VLANs on 10 Gigabit Ethernet ports, the switch displays an error message similar to the following:

  

  ERROR: The following ports do not support the MAC-Based VLAN mode; 1, 2, 10

• You can have a maximum of 1,024 MAC addresses per ExtremeSwitching switch.

Displaying FDB Information

To view network login-related FDB entries, use the following command:

show fdb netlogin [all | mac-based-vlans]

The following is sample output from the show fdb netlogin mac-based-vlans command:

Mac                    Vlan          Age     Use    Flags      Port List
------------------------------------------------------------------------

00:04:96:10:51:91      VLTWO(0051)   0100    0000   n m      v 1:11
Flags : d - Dynamic, s - Static, p - Permanent, n - NetLogin, m - MAC, i - IP,
x - IPX, l - lockdown MAC, M - Mirror, B - Egress Blackhole,
b - Ingress Blackhole, v - NetLogin MAC-Based VLAN.

The flags associated with network login 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.

Displaying Port and VLAN Information

To view information about the VLANs that are temporarily added in MAC-based mode for network login, use the following command:

The following is sample output from this command:

Port:   1
Virtual-router: VR-Default
Type:           UTP
Random Early drop:      Disabled
Admin state:    Enabled with  auto-speed sensing  auto-duplex
Link State:     Active, 100Mbps, full-duplex
Link Counter: Up        1 time(s)
VLAN cfg:
Name: Default, Internal Tag = 1(MAC-Based), MAC-limit = No-limit
...<truncated output>
Egress 802.1p Replacement:      Disabled
NetLogin:                       Enabled
NetLogin authentication mode:   Mac based
NetLogin port mode:             MAC based VLANs
Smart redundancy:               Enabled
Software redundant port:        Disabled
auto-polarity:                  Enabled

The added output displays information about the mode of operation for the network login port.

• 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 as the network login port mode of operation.

To view information about the ports that are temporarily added in MAC-based mode for network login, due to discovered MAC addresses, use the following command:

show vlan detail

The following is sample output from this command:

VLAN Interface with name Default created by user
Tagging:        802.1Q Tag 1
Priority:       802.1P Priority 0
Virtual router: VR-Default
STPD:           s0(Disabled,Auto-bind)

Flags: (*) Active, (!) Disabled, (g) Load Sharing port
(b) Port blocked on the vlan, (a) Authenticated NetLogin Port
(u) Unauthenticated NetLogin port, (m) Mac-Based port

The flags associated with network login include:

• a—Indicates an authenticated network login port.
• u—Indicates an unauthenticated network login port.
• m—Indicates that the network login port operates in MAC-based mode.

History
