Two matters you may meet:
1.The http://www.router-switch.com/Price-cisco-switches-cisco-switch-catalyst-3750_c21 Cisco L3 3750 switch (4 VLAN's /interfaces–1 for each floor) – has NO access lists on it AT ALL. This new wake on lan config requires an access list to limit/the broadcasts to be from the sccm/wol server (i dont want broadcasts accross vlans other than the wol).
2.Does UDP port sccm use for WOL broadcast?
For the question 1:
My concern is does an access-list not have an implicit deny (to all other traffic not listed) ? Answer: Yes it has (for directed broadcast, that is)
For the question 2:
Answer:I have not tryed with SCCM yet, but with Ghost we had a similar L3-switch-setup.
