WOL NX-OS 7000 Configuration

Level 1
Level 1

I'm trying to implement a WOL solution on a pair of Nexus 7ks. I have read through documentation and multiple posts and am still having trouble with it. The basic design is that I have a WOL server on vlan 10 with an address of trying to wake up a computer on vlan 30 with an ip of


On the Nexus I have an access list that is defined as such,

ip access-list WOL

permit udp host  any eq 9


Then on the vlan 30 interface I have an ip directed broadcast with the access list applied to it.

int vlan 30

ip directed broadcast WOL


I understand that on a catalyst switch there would be a ip helper-address on the vlan interface of the WOL server, but there is no ip helper address on the WOL server. I am using the Solarwinds WOL freeware tool and the AquilaWOL tool that is available on Sourceforge. Any help would be appreciated. Thank you!

On 6500s and 4500s the command you're missing is:

ip forward-protocol udp discard


ip forward-protocol udp 9

from the global config prompt.

Try that on the 7k and see if that works or has something similar.  The other piece that I'm noticing a difference is the 6500/4500s had to use a numbered extended ACL, they couldn't use a named ACL ("WOL"), because the "ip directed broadcast" command only supported a numbered ACL, not named.

Your configuration looks ok. No need for the ip helper.


did you enable WoL on the computer? (Bios,...)


f you capture in vlan 30, do you see the magic packet?



I don't know if named acl isn't supported.
