I see DHCP requests from other access points. They get an address and connect to the controller. These access points are of type 3805i.<BR /> I have configured all switch ports for access points as access ports „untagAll(access)“.<BR /> After I connect the AP3965i to the port and the boot process is complete, the port mode changes to trunk „tagAll(trunk)“.<BR /> I think this behavior is the reason why the DHCP requests from the access point do not arrive at the DHCP server. But I don't know how to configure the switch correctly.<BR /> The AP3965i previously worked correctly on an ERS4500 (with PoE + Injector). A replacement device AP3965i also shows the same behavior on the ERS4950.<BR /> Can someone help me please?</P> Fri, 24 Jan 2020 02:29:25 GMT https://community.extremenetworks.com/t5/extremewireless-identifi/ap39xx-and-ers4950/m-p/92441#M7308 Frank1 2020-01-24T02:29:25Z https://community.extremenetworks.com/t5/extremewireless-identifi/ap39xx-and-ers4950/m-p/92442#M7309 <P>Hi</P> <P>&nbsp;</P> <P>Please see the following article and see if it helps:&nbsp;<A href="https://gtacknowledge.extremenetworks.com/articles/Solution/AP-39xx-won-t-connect-to-controller-when-attached-to-Avaya-Switch-with-Fabric-Attach-enabled/" target="_blank" rel="nofollow noreferrer noopener">https://gtacknowledge.extremenetworks.com/articles/Solution/AP-39xx-won-t-connect-to-controller-when-attached-to-Avaya-Switch-with-Fabric-Attach-enabled/</A></P> <P>&nbsp;</P> <P>-Gareth</P> Fri, 24 Jan 2020 18:40:48 GMT https://community.extremenetworks.com/t5/extremewireless-identifi/ap39xx-and-ers4950/m-p/92442#M7309 Gareth_Mitchell 2020-01-24T18:40:48Z
