Need help to implement wake on lan on VDX 6740

Hello,

 

I'm trainee in a company and I need to implement Wake on LAN on the network.

 

We have in our network architecture as core network VDX 6740 with multiple VLANs (with different subnet for each VLAN) but I can ping PC which are in different subnets because we have inter-vlan routing and our network is like a simple LAN so.

 

I've spend several hours to find a great solution to make Wake on Lan to work but I'm a little lost with our actual configuration and the differents ways to make it work.

 

Then I've 2 simple questions that will maybe help me to understand easier on which commands I need to use:

 

 - Firstly  I saw that I can use ip directed-broadcast to allow broadcast on the VDX but also the possibility to use ip forward-protocol udp echo on the VLAN from where I will send magic packets.

Do I need to use the 2 commands ti make it works or only one of these two ?

 

- Secondly if I want to send my pagic packets to different subnets, do I need to use ip helper-address on each VLAN and specify the IP address of the VLAN where my WOL server is in ? I know that we have already ip DHCP relay in each VLAN but maybe it changes nothing for the functioning of WOL.

 

In any case I want to add ACL too to protect the network against smurf attacks if we enable broadcast regardless of which solution we will use, is it a good idea and is there other way to protect the network than using ACL ?

 

I've speciifically take a look at this post but I'm still not sure to which way to use to make WOL working:

Thanks

 

PS : I hope you will understand my issue because I'm not native english

I did new tests and now the wake-on-lan works in the same VLAN.

 

To make WOL work across VLANs we just needed to add the following command ip-directed broadcast on each ve interface of each VLAN where we want enable WOL

 

Hope it will help other people that could have the same issue !
