Don't forget to specify the destination port for the mirror.

You need to configure port mirroring on the router.

Wait, is this a trick question? I'm going to go with the SPAN port just to be safe.

Hmm, I'm not sure, but I think we might need to set up a VACL capture session instead.

Wouldn't a VLAN-based port mirroring be a better option in this case?

I think we need to configure a SPAN port on the router to mirror the traffic to the analyzer.

I feel like we also have to consider the VLAN settings if the traffic is tagged. That part is a bit fuzzy for me.

This seems similar to a practice question we did on port mirroring. I think we might need to enable the mirror session first?

I remember something about specifying the source and destination ports for the mirroring, but I can't recall the exact command syntax.

I think we need to configure a span or mirror port on the switch to send traffic to the analyzer, but I'm not entirely sure how to do that.

No problem, I've done this kind of thing before. I'd start by identifying the analyzer port, then set up a mirroring session to replicate the traffic to that port. Shouldn't be too tricky.

Whoa, port mirroring? I'm a little fuzzy on the details there. I'll need to review my notes and maybe look up some examples to make sure I get this right.

Ah, this is a classic network monitoring setup. I'd first determine if the router supports port mirroring, then configure a session to copy the traffic to the analyzer port.

Okay, so I need to set up a mirror for the traffic. I'm not totally sure how to do that, but I think I'll need to look at the router configuration and find the right commands.

Hmm, this seems straightforward. I'd start by identifying the port the analyzer is connected to and then configure a mirroring session to replicate the traffic to that port.
