Hi trev2hi,  You should be able to get the MAC address from the RPA by doing the following depending on the version of RP you have:  This is the equivalent of an ifconfig and should show you the interface along with HWaddr (MAC) address. You would want to locate the interface that relates to your WAN interface.  This is a sample output from my test vRPA on my lapcolor: #ff0000;">[3] Diagnostics [4] Cluster operations [5] Shutdown / Reboot operations Quit Chris-Test RPA 1: 3   ** Diagnostics ** [1] IP diagnostics [2] SAN diagnostics [3] Synchronization diagnostics [4] Collect system information Main Menu  Back Quit Chris-Test RPA 1: 1   ** IP diagnostics ** [1] Cluster connectivity tests [2] View IP details [3] View routing table [4] Ports diagnostics [5] System connectivity Main Menu  Back Quit Chris-Test RPA 1: 2 eth0      Link encap:Ethernet  HWaddr 00:0c:29:29:cf:a5           inet addr:192.168.136.132  Bcast:192.168.136.255  Mask:255.255.255.0           inet6 addr: fe80::20c:29ff:fe29:cfa5/64 Scope:Link           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           RX packets:2702 errors:0 dropped:0 overruns:0 frame:0           TX packets:1234 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:250118 (244.2 KiB)  TX bytes:134871 (131.7 KiB)   eth0:1    Link encap:Ethernet  HWaddr 00:0c:29:29:cf:a5           inet addr:10.77.77.77  Bcast:10.77.77.255  Mask:255.255.255.0           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1   eth1      Link encap:Ethernet  HWaddr 00:0c:29:29:cf:af           inet addr:192.168.136.130  Bcast:192.168.136.255  Mask:255.255.255.0           inet6 addr: fe80::20c:29ff:fe29:cfaf/64 Scope:Link           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           RX packets:3546 errors:0 dropped:0 overruns:0 frame:0           TX packets:29 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:317488 (310.0 KiB)  TX bytes:2250 (2.1 KiB)   eth2      Link encap:Ethernet  HWaddr 00:0c:29:29:cf:b9           inet addr:192.168.136.150  Bcast:192.168.136.255  Mask:255.255.255.0           UP BROADCAST MULTICAST  MTU:1500  Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)   eth3      Link encap:Ethernet  HWaddr 00:0c:29:29:cf:c3           inet addr:192.168.136.151  Bcast:192.168.136.255  Mask:255.255.255.0           UP BROADCAST MULTICAST  MTU:1500  Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
I am troubleshooting an issue at a remote site where I believe that the WAN interface on one of our RPAs has had it's switchport set to the wrong VLAN. I am trying to find the MAC address of the interface from within the CLI but am having no luck. Is there a way for me to do this?
How to determine MAC address of WAN interface on physical RPA via CLI?
