How do I find the MAC address of an IP address associated with our ASA firewall?

Hello - we have Microsoft troubleshooting a DHCP-related case for us, and they're seeing traffic coming from an IP address that is tied to our ASA gateway firewall.  There are 2 subnets going thru our network, so there are 2 IP gateway IP's associated with our firewall - 192.168.1.254 and 192.168.5.254.  They're asking for the MAC address of the 192.168.5.254 IP.  How do I find this?  I'm trying Experts Exchange to see if its faster than asking Cisco.  I've Googled it for 15 minutes and am not finding the answer so far.

thanks!

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Heloo,

You can use the CLI to find the MAC address of both. Example - show interface gigabitEthernet 0/0. Please let me know if you have any other questions and I hope I was bale to help.

Thank You

Hi,

When you issue the command show ip interface gi0/0 for exaple you will see the IP address and MAC address associated with that interface. Please let me know if that works.
