Thanks, Jeremy, great in-depth video, However, quiz-4 seems to be the wrong answer (b & c). correct should be (a & c), as, ESS - each BSS can use the same SSID (23:00); however, when we talk about multiple VLAN on the same BSS, we have different SSID and different BSSID ( one assigned as virtual BSSID assigned as incremented value) (25.40) - Correct?

@JeremysITLab 2 жыл бұрын

25:40 demonstrates creating multiple BSSs, each mapped to a different VLAN on the wired network. It's not referring to ESSs.

@karuppasamypandian5226 Жыл бұрын

Thank you so much 😊

@UnforgivenApocalypse Жыл бұрын

Quick question: if a single AP is providing multiple BSSes how are the BSSIDs formatted? Does the WAP have a single MAC it increments? Or does each BSS transmit from a distinct radio inside the WAP, which in turn has a distinct MAC?
