Comware

We are trying to implement a WOL (Wake on LAN) solution. Some of our sites have machines on seperate VLANS.

We would prefer to use a WOL program from one system to send the "magic packet" versus one of each VLAN.

I have been looking online and we found the commands for ip directed-broadcast and ip udp-bcast-forward. From the sparse examples we seem to have the ip forward-protocol part setup correctly.

The settings are:
VLAN 1:
xxx.xxx.26.255 port 9

VLAN 40:
10.xxx.1.255 port 9

We want the send the packet from VLAN 1 to VLAN40 so it will be broadcast there, and it looks like it should be correct, but the packet never goes.

Any help would be greatly appreciated.

Hi,

A quick checklist :

- Do you have routing enabled on the switch?
- Do you have an ip on both of those VLANs?
- Have you enabled "ip udp-bcast-forward"?

We do have routing enabled on the switches.
The VLANs are assigned IP addresses.
We have enabled both ip udp-bcast-foward and ip directed-broadcast.

Like I mentioned before the examples for this are really sparse, the manual really only had one and that was vague.

Ok, from my understanding the address you need to have under the VLAN 1 config (where the broadcast originates) is the broadcast address for the hosts in VLAN 40.
Without seeing more of the config I can't tell whether the address ranges above are correct.
For the above to be correct the hosts in VLAN 40 would be xxx.xxx.26.xxx, is that right?
You shouldn't need anything under the VLAN 40 config if that's the "receiving" VLAN.

Thanks!
That was the part we were missing.
Knowing that we need the other VLANs broadcast address on the first VLAN did the trick.

Thanks Again!
