WOL and timed ACLs

Unanswered Question

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.

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