DHCP issues

[Jose]

Ok guys

 

Have a strange issue with netgear vlans and DHCP,

 

DHCP on the vlan with the dhcp server works fine for both startup and IPconfig /renew, all clients can get a ip and also renew it fine on the default vlan.

DHCp works fine on all the vlans when a client boots up, if we disable the nic and reable it works fine.

 

The issues is when clients on remote vlans try to ipconfig /renew and request a new ip. This fails.

 

Can anyone help ?

Have you set the relay agent in your layer3 switch to tell it to route all of your dhcp traffic to your DHCP server?

 

We have the 6 x GSM7352Sv2 as our core, soon to be replaced with 4 x XSM7224s and we had to set two settings;

 

 

01.

System > Services > DHCP Relay

Enable Admin Mode

 

02.

System > Services > UDP Relay

Server IP and select DCHP in the UDP settings
