Refer to the exhibit. Two data-center fabrics use vPC data center interconnect. SW1 has the system MAC value 00:23:04:ee:be:20. Which value must be configured for the system MAC address?

  • A 00:23:04:ee:be:14 on SW3
  • B 00:23:04:ee:be:20 on SW3
  • C 00:23:04:ee:be:14 on SW2
  • D 46:43:32:e5:92:80 on SW2
Explanation

Each vPC domain uses a shared system MAC on its two local peer switches for link-scope operations such as LACP. For a vPC DCI, the vPC domains in the two data centers must use different system MAC addresses when the domain IDs are the same. 00:23:04:ee:be:14 is configured on SW3, and the same value must be used by its local peer SW4; it is distinct from the SW1/SW2 system MAC.
