Information About Interface Groups

Interface groups are logical groups of interfaces. Interface groups facilitate user configuration where the same interface group can be configured on multiple WLANs or while overriding a WLAN interface per AP group. An interface group can exclusively contain either quarantine or nonquarantine interfaces. An interface can be part of multiple interface groups.

A WLAN can be associated with an interface or interface group. The interface group name and the interface name cannot be the same.

This feature also enables you to associate a client to specific subnets based on the foreign controller that they are connected to. The anchor controller WLAN can be configured to maintain a mapping between foreign controller MAC and a specific interface or interface group (Foreign maps) as needed. If this mapping is not configured, clients on that foreign controller gets VLANs associated in a round robin fashion from interface group configured on WLAN.

Creating Interface Groups

Before You Begin

You must create the interface groups using the following commands after you configure the terminal.

SUMMARY STEPS

    1.    vlan group groupname vlan-list 1-256

    2.    wlan wlanname 1 wlanname

    3.    client vlan vlangrp1


DETAILED STEPS
      Command or Action Purpose
    Step 1 vlan group groupname vlan-list 1-256
     

    Creates a VLAN group with the given group name and adds all the VLANs listed in the command. The recommended number of VLANs in a group is 128.

     
    Step 2 wlan wlanname 1 wlanname
     

    Enables the WLAN to map a VLAN group.

     
    Step 3 client vlan vlangrp1
     

    Maps the VLAN group to the WLAN.

     

    Adding a VLAN Group to a WLAN

    SUMMARY STEPS

      1.    conf t

      2.    wlan wlanname 1 wlanname

      3.    client vlan vlangrp1

      4.    end


    DETAILED STEPS
        Command or Action Purpose
      Step 1 conf t


      Example:  

      Enters global configuration mode.

       
      Step 2 wlan wlanname 1 wlanname


      Example: 

      Enables the WLAN to map a VLAN group.

       
      Step 3 client vlan vlangrp1
       

      Maps the VLAN group to the WLAN.

       
      Step 4 end


      Example: 

      Returns back to exec mode.

       

      Configuring the Trunk Port

      Before You Begin

      You must configure the VLAN after configuring the controller port as a trunk port. We recommend that you configure the trunk port first and then associate the VLANs to the trunk port.

      SUMMARY STEPS

        1.    show wireless interface summary

        2.    show run int te1/0/1

        3.    interface TenGigabitEthernet1/0/1

        4.    switchport trunk allowed vlan 1-10

        5.    switchport mode trunk

        6.    nmsp attachment suppress

        7.    end


      DETAILED STEPS
          Command or Action Purpose
        Step 1 show wireless interface summary


        Example:  

        Displays all the wireless interfaces in the controller.

         
        Step 2 show run int te1/0/1


        Example: 

        Displays the running configuration available in the controller.

         
        Step 3 interface TenGigabitEthernet1/0/1


        Example:interface TenGigabitEthernet1/0/1  

        Configures the 10-Gigabit Ethernet.

         
        Step 4 switchport trunk allowed vlan 1-10
         

        Configures the trunk port.

         
        Step 5 switchport mode trunk
         

        Configures the switch port mode as a trunk.

         
        Step 6 nmsp attachment suppress
         

         
        Step 7 end
         

        Returns to EXEC mode.

         

        Configuring VLAN Interfaces (GUI)

        Before You Begin

        You can configure VLANs in the controller using the web UI. To do this, you must follow the steps defined in this module in the web UI.

        SUMMARY STEPS

          1.    Choose Configuration > Controller > System > Interfaces > VLAN Summary.

          2.    Click the VLAN ID field in the table to view the details of the selected VLAN.

          3.    Enter the values.

          4.    Click Apply.

          5.    To create a new VLAN, click New.

          6.    To delete a VLAN, check the check box in the VLAN summary page, and click Remove.


        DETAILED STEPS
          Step 1   Choose Configuration > Controller > System > Interfaces > VLAN Summary.

          This page displays all the VLANs and details of the VLANs in the controller.

          Step 2   Click the VLAN ID field in the table to view the details of the selected VLAN.

          The Edit VLAN details page appears.

          Step 3   Enter the values.
          Step 4   Click Apply.
          Step 5   To create a new VLAN, click New.
          Step 6   To delete a VLAN, check the check box in the VLAN summary page, and click Remove.
