Also installed wireshark on the WoL sending PC and on a PC connected to vlan1. Ip helper-address (vlan 2 gateway) tried with and without this settingĭownloaded EMCO and Solarwinds WoL utilities. I made the changes in a test environment (single 35) which were loaded with the exact configs of the production switches.Īccess-list 101 permit udp host 192.168.1.145 any eq 7 I'm trying to get an idea of what is blocking WoL between PC's connected to the same 3560 switch but on different vlans, because I can take PC1 and just a retail 4 port switch and connect it to PC2 (creating its own two PC network) and have WoL work every time. So my question, since different vlans are on SW1, does communication from PC1 go through SW1 to the 3750 Core switch, and then back to SW1 and then to PC2? or does the SW1 (the 3560) handle the communication in vlans connected to it? Sending a WoL packet from PC1 to PC2 works only intermittently, it has worked, but rarely. PC1 on vlan2 connected to a 3560, call it SW1 Which leaves really only one question, which is about the 3560 switch blocking WoL. Thank you for answering Rick, that is really helpfull and makes it sound a lot easier. You may need to configure ip forward-protocol to define the port number used for WOL packets. There are some other things that you may need to do depending on things in your network. This will allow forwarding of directed broadcasts (which is disabled by default). on any layer 3 vlan interface for vlan 1 configure ip directed-broadcast. This will forward WOL packets to the broadcast address of the other subnet. on the layer 3 vlan interface where the WOL packets will be received (vlan 2) configure ip helper-address with the broadcast address of the subnet in vlan 1. I am not sure which document you are referring to, but here is my quick summary of the simple way to enable WOL: If the WOL is being blocked it is much more likely that it is being blocked by the default action of not forwarding broadcasts between vlans/between subnets. portfast allows a connected device (like a PC) to get to the forwarding state more quickly. No disabling portfast would not block WOL. Yes it is possible to allow an entire vlan to execute WOL or to allow multiple IPs.
