S3500 dhcp-relay

[Jaasperff]

I need to setup dhcp relay on a S3500 switch running Version 7.1.3.0

I believe I have it set up right and that there is a problem in my dhcp server but just in case I got it wrong or I'm missing something I thought I better put up this post.

First set up the relay profile

(ArubaS3500-24-POE) (config) # interface-profile dhcp-relay-profile 1
(ArubaS3500-24-POE) (dhcp relay profile "1") #helper-address 172.16.1.254  <-- Your dhcp server ip address

Then apply the profile to the vlan interface

(ArubaS3500-24-POE) (config) #interface vlan 3

(ArubaS3500-24-POE) (vlan "3") #dhcp-relay-profile 1 

(Aruba-24-POE_GREllington3) (vlan "3") #exit

Then of course do a wr mem.

Am I missing anything because it sure isn't working.....

Thanks guys !!!

Do you also have an IP interface on that VLAN? Otherwise the configuration looks correct.

Yes I have an IP address assigned to the interface. 

Ok. Thanks. Like I said I think there is a problem with dhcp server. 

Just wanted to confirm the config on the switch.

Team,

This thread was very handy, however I am new to 3500 (Aruba) and need to change to a new DHCP server... can some one post how to remove the profile? I am unable, says, profile in use, but no vlan interface is assigned to it..

Started with:

interface-profile dhcp-relay-profile DHCP-RELAY-Profile1 <-- Old Profile
helper-address 10.x.x.xx5 <-- Old dhcp server ip address

Created a new profile with new helper IP...

Removed the dhcp profile from vlan interface

assigned new profile to the VLAN interface...

Unable to remove old profile now?

Thanks for your help...

Is the profile tied to another interface or group?
