NV4430 with separate DHCP server - multiple vlans

I have a Linux CMS server with an IP of 192.168.16.170 that sits on vlan 41. I need it to be able to pass DHCP over to vlan 2001. I am unable to use the Adtran built-in DHCP for multiple reasons. Below is part of my config, which does not accomplish what I need:

NV4430 config:

interface gigabit-eth 0/2.41

  vlan-id 41

  ip address  192.168.31.254 255.255.240.0

  ip access-policy Private

  no shutdown

interface gigabit-eth 0/2.2001

  vlan-id 2001

  ip address  192.168.47.254  255.255.254.0

  ip dhcp relay destination 192.168.16.170

  ip access-policy Private

  no shutdown

Linux server config:

"dhcpd.conf" 34L, 1064C written

[root@cmsserver etc]#

[root@cmsserver etc]#

[root@cmsserver etc]# cat dhcpd.conf

}

Re: NV4430 with separate DHCP server - multiple vlans

To clarify, this does not work like I need it to. DHCP does not pass to vlan 2001. Any ideas?

Re: NV4430 with separate DHCP server - multiple vlans

Instead of:

interface gigabit-eth 0/2.2001

  vlan-id 2001

  ip address  192.168.47.254  255.255.254.0

  ip dhcp relay destination 192.168.16.170

Try:

interface gigabit-eth 0/2.2001

  vlan-id 2001

  ip address  192.168.47.254  255.255.254.0

  ip helper-address 192.168.16.170
