Dell Powerconnect 28xx series Multiple DNS servers

Hey,

Hey i have a Dell Powerconnect 2824 series switch and i am setting up the switch as a dhcp server for the client pc's. I want the dhcp server to assign two dns servers, one primary and a secondary dns ip. 

So basically the first dns ip would be 192.168.1.9

and the secondary dns ip is 192.168.1.10

but i cant find this setting in the switch web management console.  I can only assign a single dns ip.

I dont see an option for a second entry. in the network pool settings page there is only one option for domain name server.

There is also an option for Next server, is that an option for another dns server.

Static host is for defining a single static host its not an option to automatically assign those settings to all client pcs.

so maybe there isnt an option for assigning a secondary dns ip,

I do not see an option to configure multiple DNS servers. You can take a look under System>DHCP server>Static Hosts, just to be certain there is not a spot for a second entry.

Do you have a virtual host on the network? Another option would be to setup a more robust DHCP server on a VM.

I believe next server is for the use of PXE booting.

This is a quote from the user guide:

"Next Server — Specifies the IP address of the next server in the boot process of a DHCP client. If the

next server in the boot process is not configured, the DHCP Server uses inbound interface helper

addresses as boot servers."

Just wanted to let you know that if you do it from the CLI you can add multiple DNS for the network pool, just not with the GUI

console(config-dhcp)# do sh ip dhcp pool network "Den Scope"

       Name                Address range            Mask         Lease
------------------- --------------------------- ------------- -----------
     Den Scope        10.1.100.2-10.1.100.254   255.255.255.0  7d:0h:0m

Statistics:

 All-range   Available   Free   Pre-allocated   Allocated   Expired    Declined
----------- ----------- ------ --------------- ----------- ---------- ----------
    253         253      253          0             0          0          0


Default router: 10.1.100.1
Ping packets: enabled
DNS server: 94.140.15.15;94.140.14.49
Domain name: adhome
Time server 99.119.214.210

If you do the following command:

console(config)# ip dhcp pool network [pool name]

console(config-dhcp)# dns-server A.B.C.D<space>E.F.G.H
