no it doesnt.
In fact under general circumstances those source macs are the MAC of the
router that was the last hop onto the lan.
Although i would love to, at the moment i dont have time to explain where
arp is used and how it works =)
Now, im guessing this 6509 has an MSFC (or MSFC2) am i correct?
If so it might be a bit easier to do what you want, cause ou are looking at
IP addresses, in general, and i'm just making sure before going ahead and
giving guideance that you have that stuff =)
Don't take this post personally.

Subject: Relpys to a request [7:16980]
When an icmp echo is sent, or when a telnet connection is intiated, does the
destination PC gleen the source mac address from the echo packet/ telnet
initiation packet, or is an ARP request issued to derive the source mac? I
am trying to find out if setting up a static arp entry on a switch would
prevent someone from spoofing an allowed IP address in an ip permit list on
a 6509. Any help would be greatly appreciated.
