i'm going to go out on a limb here and say that is the dns server setting for the switch itself and has nothing to do with the ip address being advertised to your dhcp clients. i haven't really had much time to actually get to work with these switches since im ready to rip my hair out on how loud these damn things are despite fan swaps. in any case if this were any other brand switch then my previous comments would be correct and these appear to follow similar configuration parameters and can say that is the case here. where does your dhcp come from? set that value there and you will fix your issue.I am having some problems with dns for connected clients on my 7250.
I have a vlan 50 with a ve interface address of 10.1.50.1/24. I am connected to my pfsense box with a transit port - 10.1.2.2/30 on the switch and 10.1.2.1/30 on pfsense. I have set the following :
I connected my laptop to port 23 on the switch which is untagged 1/1/23 for vlan 50. The problem is, the laptop is assigned a dns server of 10.1.50.1 and there is no internet connectivity. If I manually set the dns server of the laptops connection to 10.1.2.1, everything works. I thought setting the dns server globally to 10.1.2.1 should have worked? How can I set all connected clients to have a dns server of 10.1.2.1 instead of 10.1.50.1 ?Code:
ip dns server-address 10.1.2.1 # pfsense transit ip ip route 0.0.0.0/0 10.1.2.1 # ip helper for vlan 50 ip helper-address 1 10.0.0.41
this should be what you're after assuming the switch is your dhcp server.
ip dhcp-server pool YOUR-DHCP-POOL-NAME dns-server 10.1.2.1
