How to check the management-interface mac-address of a Dell switch?
Hello
To register the Dell Switch NMS system, you need to register the mac address of the management interface.
Even if the N2048-ON device does not have an oob port (management interface port), the mac address is resolved from the mac address table.
The N2048-ON management interface mac-address I found is:
N2048-ON(OS6)
In case of N2048-ON device, mac-address is displayed as vlan1 even though there is no management interface.
Is the mac address in mac-address-table the management-interface mac-address, not vlan1?

Dell_sss,
So for N2048, it does not have the dedicated MGMT port which cannot have a MAC address for the MGMT. It will have the L3 MAC Address which is the MAC the VLAN will use. Not sure if you can register that with NMS system but that MAC can be used when setting a DHCP reservation. All layer-3 interfaces have the same MAC in Dell OS6/9/10.
Hope this helps.

Dell_sss,
I may be misunderstanding your request, if not then what you're looking for may be found on page 228 here but since the switch doesn't have a dedicated management port it uses vlan 1 and is accessible from any port, it is more of a virtual management interface but that should work the way you want.
Let me know if this helps, or if I misunderstood your request.

Thanks for the reply
But that's not what I want to know.
Let's talk about N2048-ON switch by comparing N3048-ON and S3048-ON.
Below is the mac address of the switch checked by "show system" and "show mac address table" and the mac-address of "switch mgmt interface"
1. N3048-ON
N3048-ON mac-address : F8B1.5674.2A1F
N3048-ON management-interface mac-address : F8B1.5674.2A22
2. S3048-ON
S3048-ON mac-address : 3c:2c:30:ac:79:00
S3048-ON management-interface mac-address : 3c:2c:30:ac:79:02
N-switch becomes F8B1.5674.2A22 by +3 from F8B1.5674.2A1F which is the system mac address
S-switch becomes 3c:2c:30:ac:79:02 by +2 from 3c:2c:30:ac:79:00 which is the system mac address
In the case of the above equipment N3048-ON, S3048-ON, the above phenomenon can be understood because there is a management interface.
However, in the case of N2048, I can't understand the management interface that appears in the show mac address table because there is no management interface.
I'm wondering if the vlan1 mac address or mgmt interface mac address shown in the N2048-ON mac address table looks like this:
