Refer to the exhibit. Two data center fabrics use VPC data center interconnect. The system MAC value on SW1 is 00:23:04:ee:be:20. Which value must be set to configure the system MAC address?
A is correct. SW1 has a system MAC address of 00:23:04:ee:be:20.
You need to configure the system MAC address for SW3 or SW2 in this vPC environment.
The system MAC address must match for switches in the same vPC domain. ; C and D are not correct because SW2 mac should be the same as SW1 (00:23:04:ee:be:20): B is not correct because because mac address of SW3 must be different than mac address of SW1 or SW2 ; so the right answer is A because the mac address is different than the mac address of SW1 or SW2
System MAC Address
Switch-Specific:
Unique to Each Switch: Each switch in a vPC setup has its own unique system MAC address. This MAC address is specific to that individual switch and is used for internal operations, such as control plane communication and management.
Internal Operations: The system MAC address is used by the switch for various internal processes, including maintaining the MAC address table and handling certain types of control plane traffic. Cannot be D because is complete different MAC address
Answer should be C, in my opinion:
VPC peer of sw1 is sw2 and they have to be the same vendor
Each vPC domain has a unique MAC address that is used as a unique identifier for the specific vPC-related operation. Although the devices use the vPC system MAC addresses only for link-scope operations such as LACP
