Wake on LAN between 5406zl and 2810-48G switches

[tlovegrove]

Hi everyone, been browsing the forums and can't find a match for my situation, hope people can offer some help.

I have two ProCurve 5406zl's set up as a trunked, fail-over pair of core switches. These manage a number of VLANS ("Servers", "Workstations", "CBT" etc), and further ProCurve 2810-48G switches hang off the core switches to provide access to the "Workstations" and "CBT" VLANS.

I'm trying to configure a Wake on LAN server to boot the user workstations. The WOL server is sitting on the core switch's main "Servers" VLAN, and is able to boot other machines on the same subnet. I have enabled "IP directed-broadcast" on all the relevent VLANS on the 5406's, however the WOL packets still aren't making it through to the "Workstation" or "CBT" VLANs.

Have I missed a step of the config? All the info I've found so far implies that simply turning on the Directed Broadcast on a per-VLAN basis should be enough. The ACL's between VLANS are open, so any traffic can flow between these three VLANS, so I'm guessing the WOL broadcast is being binned somewhere, presumably by the 2810's.

Any help greatly appreciated, further info available on request.

Rgds,

Hi everyone, some additional information I've found may have been misleading me slightly. I've been using the "Magic Packet Utility" to achieve this task, and it consistently fails to works. It will collect IP's and MAC addresses from its own subnet but simply won't talk to other subnets. Likewise it will wake up machine on its own subnet but can't wake machines on other subnets.

However having now played with the Depicus WOLCMD program, this does seem to be able to wake machines cross-subnet and is somewhat more script-able than the MPU, so looks like the way to go.

If you want your original tool to work, you will probably need to configure the UDP helper feature on your routing switch. Can't remember the exact command, but the idea is the same as with IP-helper (used for DHCP), only now for broadcasts to a specified UDP-port.
