WOL and timed ACLs

a.whiting · ‎06-18-2009

Hi folks,

Anybody had experience of WOL and timed ACLs on switchports, please?

Current scenario is switchports' ACL only permits IP during working hours (defined in a time-range) but we want to roll-out the 1E WOL & NightWatchman tool to reduce workstation power consumption.

I can see an impending problem here, in that the port is shut (to IP) when WOL arrives.

Question is: Can I modify the ACL to sniff the WOL packets, or is there a better way?

Regards,

Andy.

Wake-On LAN packets are Layer2 while your ACL, as stated, are functioning at Layer3.

More information on WOL Magic Packets:

In conclusion, the WOL process won't be prevented by the ACLs.

HTH,
