Different interfaces have same MAC address
Hi,
On the AR651-X8, two interfaces have the same MAC address. Both interfaces are Layer 3 interfaces and are connected to different PEs.
Device version: V300R019C00SPC300.
interface GigabitEthernet0/0/1
undo portswitch
ip address 10.xx.xx.14 255.255.255.252
#
interface GigabitEthernet0/0/2
undo portswitch
ip address 10.xx.xx.62 255.255.255.252

Hello, This is normal for your device. Regarding the AR device interface mac address allocation, the following rules apply:
For this device, The G0/0/1 and G0/0/2 are LAN port by default, so the ports use the system MAC address. And the mac addresses not change when the ports switch to Layer 3 mode:
You can change MAC address refer following command. [AR651]interfaceGigabitEthernet 0/0/1 [AR651-GigabitEthernet0/0/1]mac-address XXXX-XXXX-XXXX |
