Hello,  We currently use IP directed broadcast to allow wake on LAN for our  460-48p (G1) switches running 16 code.   On occasion we'll have a field tech tell us that WOL isn't working.

Other than confirming that the ip directed broadcast settings are on all appropriate vlans on the core, what else can I check?

Thank you,

Sarah

Hi Sarah,


Create a policy file to be applied as a UDP profile. The format for this policy is below​.


entry one {
     if match all {
           destination-port 9;
     } then {
           vlan <VLAN_NAME>;
     }
}
 
entry two {
     if match all {
           destination-port 9;
     } then {
           vlan <VLAN_NAME>;
     }
}


Apply this policy to the VLAN that the WoL server is in, with the command configure vlan <VLAN_NAME> udp-profile <PROFILE_NAME>


Note:

-We can have 1 UDP broadcast packet to 8 destination (vlan)
-It is not recommended to have more than 8 entries in a UDP profile.

Regards,
Karthikeyan

Thank you for the response.  Is it REQUIRED to have this AND the ip directed broadcast to have WOL successfully work?

Guess I'm trying to nail down where the issue could be.  Is it b/c I don't have the profile defined that it sometimes works sometimes doesn't?

Will having the profile defined make it work better?

Or is it simply a requirement for WOL to operate, to have this UDP profile defined on our gear?  

(Additionally We don't use netlogin so the second post doesn't' apply here.)
