Setting up Secondary DHCP to Brocade ICX 6610

Hello,

Currently We have a Brocade ICX 6610 acting as our gateway and has a Adtran 4430 connected to it acting as a DHCP server. We have few vlans on it. I am trying to set up a new Microsoft DHCP server on another interface so that we can start moving from Adtran to MS DHCP. 

My new vlan has a subnet of 104.153.30.0/24 the Brocade gateway:104.153.30.1 and the DHCP: 104.153.30.2

Following is my config for the new connection

!

vlan 135 name Cust_data_4 by port
tagged ethe 1/1/2 ethe 1/3/1 to 1/3/2
untagged ethe 1/1/5
router-interface ve 135

!

ip route 104.153.30.2 255.255.255.255 ethernet 1/1/5

!

interface ethernet 1/1/5
port-name Cust_data_4
sflow forwarding

!

interface ve 135
port-name Cust_Public 4
ip address 104.153.30.1 255.255.255.0
ip helper-address 1 104.153.30.2

!

 

However I dont seem to be getting an IP address when I connect. I have a few Adtran gpon Chassis connected on eth 1/3/1 . My system is connection to one of the ONTs on the Gpon Chassis. The same set up seems to work if I provision my conneciton on an existing vlan .

Please help.

Rohit

Re: Setting up Secondary DHCP to Brocade ICX 6610

Hi Sir

it seems that you have been cofused.

you have a vlan: 135 , and you have a DHCP server directly connected to the switch(104.153.30.2). You have an ip address with the same subnet of DHCP server and in additon you have a route to ethernet 1/1/5. :)

 

you don't have to do the routing through the eth 1/1/5 ( ip route 104.153.30.2 255.255.255.255 ethernet 1/1/5 ). 

you don't have to configure a DHCP server on vlan 135 ( ip helper-address 1 104.153.30.2 )

 

if you add an other port to vlan 135 it will take an ip address (untagged ethe 1/1/6). if you can not; check the DHCP server scopes. 

if you have different vlans(not 135) you have to configure helper address under the ve interfaces.

 

but kindly i sugggest you to have a professional help.

 

Regards.
