You are troubleshooting an issue with a pair of Aruba CX 8360 switches configured with VSX Each switch has multiple VRFs. You need to find the IP address of a particular client device with a known MAC address You run the "show arp" command on the primary switch in the pair but do not find a matching entry for the client MAC address.
The client device is connected to an Aruba CX 6100 switch by VSX LAG.
Which action can be used to find the IP address successfully?
A)
B)
C)
D)

I’m not sure. Maybe we should analyze the VSX setup first?

I agree with Option C. It’s the most straightforward approach.

I’m leaning towards Option A. It could help us trace the MAC better.

Option B seems good too. It might show the correct ARP table.

Option C seems like the best choice here!

Wait, are you sure it’s not a VLAN issue?

I thought the primary switch would have the entry, though.

Totally agree, that's where the client is connected!

You should check the ARP table on the Aruba CX 6100 switch.

Haha, this question is like a game of hide-and-seek with the client's IP address. Time to put on our detective hats!

Option D is the way to go. Gotta love those Aruba CLI tricks!

I'm going with Option C. Seems like the most straightforward way to get the IP address.

Looks like we need to check the VSX LAG on the Aruba CX 6100 switch. That's probably where the client's IP is hiding.

I vaguely recall that we might need to check the VRF settings too. If the client is in a different VRF, it could explain why we can't see the MAC on the primary switch.

I'm not entirely sure, but I feel like there was something about using "show mac-address" commands in our practice. Is that relevant here?

I think I saw a similar question where we had to look at the LAG configuration. Could it be that the MAC is only visible on the 6100 switch?

I remember we discussed how ARP entries can sometimes be missing if the device hasn't communicated recently. Maybe I need to check the other switch?

Alright, I think I've got it. The client is connected to the Aruba CX 6100 switch, which is part of the VSX pair. So I need to check the ARP table on the secondary switch, which is Option B. Feels like a good strategy to tackle this one.

I'm a bit confused by this one. The client is connected to a different switch, but the question is asking about the primary switch. I'm not sure which switch's ARP table I should be checking. Maybe I should read through the options again more carefully.

Ah, I see what's going on now. The client is connected via a VSX LAG, so the IP address might be in the ARP table of the secondary switch. I think Option B is the way to go here.

Hmm, this one's tricky. Gotta think outside the box to find that IP address.

I feel confused about the options. What does each one do?

I think we should go with Option C. It makes sense for VRF troubleshooting.

Okay, let's see here. Since the client is connected to a different switch, I'm guessing I'll need to check the ARP table on that switch instead. Option C looks promising, but I'll need to double-check the details.

Hmm, this looks tricky. The client device is connected to a different switch, so the "show arp" command on the primary switch may not show the IP address. I'll need to think carefully about the options.

Or we could check the VSX configuration for any clues.

That could work! It might show us the IP linked to that MAC.

Maybe we should try the "show mac address-table" command on the 6100?

Right! The client is on the Aruba CX 6100, not the 8360.

I agree, it's definitely tricky. We might need to check the other switch.
