How many DHCP option 150 supported on MAS?

Aruba Employee
Q:

 Does Aruba Mobility Access Switch and Controller support multiple DHCP option 150?



 



A:

 No, DHCP option 150  contains the IP address of the TFTP server. This popularly used by Cisco VoIP phones  to download the configuration from a centralized server or call manager.

                The DHCP  server will return with a list of IP address in Option 150 which can be used by the phones.

                 Currently Aruba Controller  and MAS  support only one DHCP option with below configuration.

 

(Controller) # configure  terminal

(Master-Controller) (config) #ip  dhcp pool vlan20

(Master-Controller) (config-dhcp)#option 150 ip 10.192.5.2

 

# vlan20
subnet 20.20.20.0 netmask 255.255.255.0 {
        option vendor-class-identifier  "ArubaAP";
        option vendor-encapsulated-options  "10.17.170.227";
        option domain-name-servers 8.8.8.8, 4.2.2.2;
        option routers 20.20.20.1;
        option usr-opt-150-3 10.192.5.2;
        range 20.20.20.2 20.20.20.254;
        authoritative;
