Discuss HP HPE7-A01 Exam Topic 7 Question 8

With the Aruba CX 6100 48G switch with uplinks of 1/1/47 and 1/1/48. how do you automate the process of resuming the port operational state once a loop on a client port is cleared?

AConfigure int 1/1/1-1/1/52 loop-protect disable timer.

BConfigure global loop-protect disable timer.

CConfigure int 1/1/1-1/1/46 loop-protect re-enable-timer.

DConfigure global loop-protect re-enable-timer.

Suggested Answer: C

Loop protection is a feature that detects and prevents loops in layer 2 networks. Loop protection can be enabled on ports, LAGs, or VLANs. When loop protection is enabled, the switch sends periodic loop protection messages on the interface and expects to receive them back.If a loop protection message is received back on the same interface, it indicates a loop and the switch takes an action to disable the interface or block traffic on it3. The loop-protect re-enable-timer command is used to configure the length of time the switch waits before re-enabling an interface that was disabled due to loop detection.The default value is 0, which means that the interface remains disabled until manually re-enabled3.To automate the process of resuming the port operational state once a loop on a client port is cleared, the loop-protect re-enable-timer command can be used with a non-zero value on the interface range that includes the client ports3. Therefore, answer C is correct.

Really? I thought we had to disable it first before re-enabling.

I heard loop-protect can be tricky, but D seems solid.

Denae 11 months ago

Wait, isn't option C better for specific ports?

Winifred 12 months ago

Definitely agree with that! Global timers make sense.

Maryann 12 months ago

I think option D is the way to go for global settings.

I vaguely remember that the re-enable timer is crucial for resuming port operation, but I can't remember if it should be set globally or per interface.

Milly 1 year ago

I feel like the global settings are usually more effective, but I can't recall if that's the right approach for this specific switch model.

Kayleigh 1 year ago

I think we practiced a similar question where we had to set a re-enable timer for loop protection. Could it be option D?

Camellia 1 year ago

I remember something about loop protection, but I'm not sure if it's the global or interface-specific settings we need to focus on here.

Vicky 1 year ago

Ah, I've seen this type of question before. The key is to configure the right timer, either globally or for the specific ports. I think I've got this one figured out, but I'll double-check my work just to be sure.

Mauricio 1 year ago

Whoa, this is a new one for me. I'm not too familiar with the loop-protect feature and how to automate the port state resumption. I'll need to do some quick research to make sure I understand the concepts before selecting an answer.

Shawn 1 year ago

Alright, this is a good test of my Aruba CX switch knowledge. I'm pretty confident I can identify the right solution here, but I'll make sure to read the question and options thoroughly.

Andra 1 year ago

Okay, let me see here. I think the key is to find the right timer configuration, either globally or just for the specific ports. I'll need to double-check the syntax, but I think I can figure this out.

Irene 1 year ago

Hmm, this looks like a tricky one. I'll need to carefully read through the options and think about the specific configuration required to automate the port state resumption.

Armanda 1 year ago

Okay, I think I've got this. I'll just need to find the 'Try Research' text on the slide and insert the hyperlink. Shouldn't be too hard.

Celeste 1 year ago

I thought global variables could be changed easily, but I can't recall if there are restrictions like option D suggests.
