Native Vlan Cisco 1200 Access Point

    Hello again,

    In the configuration guide for Cisco 1200 series access points, ver
    12.3.7 on page 14-5 it states that "When you configure Vlans on access
    points, the Native Vlan must be VLAN1." Is this correct? What if the
    switch trunk port is Vlan 4 or something to that effect.

    Thanks,

    It is doubtful that they made a special note in the prodcut
    documentation if it is not the case.

    Generally it is best to not use VLAN 1 at all or use it for mgmt
    purposes only - telnet SNMP, etc.

    There should be no need to change the native VLAN (VLAN 1), just add
    the additional VLANs that you require for your setup.



    int Fa0.1
    encap dot1Q 1 native
    exit

    int Fa0.4
    encap dot1Q 4
    bridge-group 4
    exit


    int dot11radio 0
    ssid WIRELESS
    vlan 4
    exit


    int Dot11Radio 0.4
    encap dot1Q 4
    bridge-group 4
    exit

    Configure upstream switch accordingly.

    OK<

    But if the native VLAN is 1 on the access point then the native VLAN on
    the switch for the trunk port must be VLAN1. This is what I'm
    concerned about. Everyone states to stay away from VLAN1. Thanks for
    your reply.

  4. Technically: AP IOS requires that it have exactly one IP
    address, which must be configured on BVI1, which must
    be in the (untagged) native VLAN.

    You can call the native VLAN anything you want, vlan 1 or
    vlan 47 ... what you call the native VLAN on the AP is
    really private to the AP. EXCEPT that the AP will always
    (if configured with dot1q encapsulation) send out its CDP
    and Ethernet keepalives on VLAN 1 (whether or not you've
    configured a VLAN 1)

    .... so it's best just to use native VLAN 1 and be done
    with it.
