DHCP-relay function in an "WS-C2960-24PC-L"?

[kvessgard]

Is it possible to establish an "DHCP-Relay"-function in an "WS-C2960-24PC-L" or do I need a router (L3).?

Hi Kvessgard,

I think this is supported on 2960 with LAN base Image:

Here is the link:

Hi

Yes I have read this information but I can´t figure out how to use it?

Do you have an sample for this?

I do have an Vip-Device on a port on such a switch

and the DHCP-server is on another LAN.

The vlan that the device is in should have a L3 vlan interface ? So, for example, if the vlan was vlan 10 in your config you should see something like  -

int vlan 10

ip address

if you do then under that vlan interface configure an ip helper-address ie.

int vlan 10

ip address

ip helper-address x.x.x.x  <--- where x.x.x.x is the IP address of the DHCP server.

Hi ,

U must have a vlan on switch.

Just assign:

Interface vlan x

ip helper-address

make sure your VIP device conected to right port on switch.

Hi,

Please don't forget to turn on "service dhcp", else the helper isn't enaged; sorry if granny and eggs though!
