We have one site with the following configs:
Location A
Core switch (Summit x450a running XOS 15.3.4.6) that is connected to a desktop stack (Summit x440 running XOS 16.2.4.5)
Location B
Core switch (Summit x460-G2 running XOS 22.4.1.4 patch 1-2) that is connected to a desktop stack (Summit X440G2 running XOS 22.4.1.4 patch 1-2)
In both sites, there is a Utility VLAN (where the server sending out the WOL packet on UDP 4000 is located) and a Desktop VLAN.
In both sites, IP forwarding is enabled on both VLANs on the core switches and the desktop switches.
In both sites "enable ipforwarding broadcast" is set on the core switches for each VLAN.
When I run WireShark in both locations, I see virtually the same behavior.
1) The server sending out the WOL packet sends it to the broadcast address of the Desktop VLAN
2) Then from a system in the Desktop VLAN running WireShark, I see the switch do an ARP Broadcast (ExtremeN_36:94:98 "Who has 172.22.118.123? Tell 172.22.118.1.").
In the location with the older equipment, there is a WOL packet sent to the broadcast address of the Desktops VLAN a few miliseconds later which wakes the system. However in the new location with the X460, X440, and XOS 22.4, I never see the WOL packet sent and the systems never wake up. Is there some other change that we need to make in order to get this to work that we for some reason did not have to make with earlier versions of XOS/hardware?
