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, | ||||||||||

Please log in for more thread options 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. | ||||||||||

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. | ||||||||||

Please log in for more thread options 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.
