How do I configure the DHCP scope to import the DNS server from PPPoE?

Product and Software: This article applies to ArubaOS 3.1 and later.


In a branch-office deployment where an Aruba switch is configured to authenticate with the service provider using PPPoE, the DHCP scope can be configured to import DNS information from PPPoE.



dns-server import



(wlsw2h) (config) #ip dhcp pool users
(wlsw2h) (config-dhcp)#dns-server import



Navigate to Configuration > Network > IP > DHCP Server > Edit DHCP Scope and select "Import from DHCP/PPPoE".




To verify the DHCP, issue the following command:


(wlsw2h) #show ip dhcp database

DHCP enabled

# users
subnet netmask { 
        option vendor-class-identifier "ArubaAP"; 
        option vendor-encapsulated-options

        option domain-name-servers,; # From PPPoE
        option routers;


From this output you can see that the DNS server has been imported from PPPoE.
