When the primary VSX node is replaced and the system MAC is replaced, which description applies to VSX MAC handling?

When the primary VSX node is replaced and the system MAC is replaced, which description applies to VSX MAC handling?

• A. VSX will select the MAC address from a node that is the lower ID
• B. Configure vMAC on the Primary VSX node under VSX to retain MAC after hardware replacement
• C. VSX will select the MAC address from a node that is a higher ID
• D. During the initial VSX configuration, the system-mac is assigned with a fixed MAC based on VSX ID

Answer: (D)

In VSX, the MAC address used for the system identity is fixed and deterministic. It’s established during the initial VSX configuration and is derived from the VSX ID, giving the domain a unique, stable system MAC that remains the same even if the primary node is replaced or hardware changes occur. That’s why the description that fits best is: when you first configure VSX, the system MAC gets a fixed value based on the VSX ID. This makes the MAC identity predictable and consistent across hardware replacements. The other ideas—picking the MAC from a lower or higher node ID, or using a feature to retain MAC after replacement—don’t reflect how VSX derives and maintains the system MAC.
