HPE7-A01 Exam - Topic 6 Question 45 Discussion

Your customer currently has Iwo (2) 5406 modular switches with MSTP configured as their core switches. You are proposing a new solution. What would you explain regarding the Aruba CX VSX switch pair when the Primary VSX node is replaced and the system MAC is replaced?
D) During the initial VSX configuration, the system-mac is assigned with a fixed MAC based on VSX ID.
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.

Your customer currently has Iwo (2) 5406 modular switches with MSTP configured as their core switches. You are proposing a new solution. What would you explain regarding the Aruba CX VSX switch pair when the Primary VSX node is replaced and the system MAC is replaced?

Show Suggested Answer Hide Answer
Suggested Answer: D

The system-mac command is used to configure a fixed MAC address for the VSX system. This MAC address is used as the source MAC address for all routed traffic from the VSX node.The system-mac command is highly recommended for preventing traffic disruptions when the primary VSX switch restores after the secondary VSX switch, such as during a primary switch hardware replacement or a power outage2. During the initial VSX configuration, the system-mac is assigned with a fixed MAC based on VSX ID.The system-mac command can be used to change this default MAC address if needed2. Therefore, answer D is correct.

A is definitely wrong, it’s all about the lower ID.

I vaguely remember that during the initial configuration, the system MAC is assigned based on the VSX ID, but I’m not clear on how that affects replacements.

The key here is understanding the VSX behavior when the primary node is replaced. Option B about configuring the vMAC on the primary node seems like the most straightforward approach to retain the system MAC address. I'll focus on that as my strategy for this question.

I'm a bit confused about the specifics of VSX and how the system MAC is managed. I'll need to review the Aruba CX documentation to make sure I have a solid understanding of the VSX functionality before attempting to answer this question.

Based on the options provided, it looks like I need to focus on how the VSX system MAC is assigned and how it is retained after a hardware replacement. I'll need to carefully consider the differences between the answer choices.

Okay, let me think this through. The key is understanding how VSX handles the system MAC address when the primary node is replaced. I'll need to review the VSX configuration options to determine the best approach.
