Mac Address For Access Point6/24/2021
MAC addresses - hardware addresses that uniquely identifies each node of a network.It is assigned by the vendor or manufacturer and saved to the device memory.In IEEE 802 networks Data Link Control (DLC) layer is divided into two sub-layers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer.
The highest ranked answer on the linked question gives me more info than I need, which didnt let me figure out which of the two MAC addresses my printer was listing belonged to the SSID my laptop is connected to. For example, to list some common information including SSID, access point MAC (BSSID), channel frequency, signal strength etc. Not the answer youre looking for Browse other questions tagged wireless or ask your own question. With MAC addresses, there is no hierarchy, and thus packet forwarding would not be possible. So my question is, where exactly does a MAC address come into play during a packet transfer. Packets that are sent on the ethernet are always coming from a MAC address and sent to a MAC address. If a network adapter is receiving a packet, it is comparing the packets destination MAC address to the adapters own MAC address. If the addresses match, the packet is processed, otherwise it is discarded. There is a special protocol ARP (address resolution protocol) that is used for that. Once the sender has retrieved the MAC address of the next hop, he writes that target MAC address into the packet and sends the packet. When a device wants to know the MAC address for a given IP address, it sends a packet to the broadcast MAC address asking Who has IP address y.y.y.y All devices receive that packet, but only the one with the IP address y.y.y.y will respond with a packet Its me. The asking device receives the answer and now knows that the source MAC address is the right MAC address to use. Of course the result will be cached, so the device does not need to resolve the MAC address every time. Low level ethernet and MAC addresses can only reach every device on the same network (cabled or wireless). If you have two networks with a router in between you cannot have a device in network A send a packet to the MAC address of a device in network B. No device in network A has the MAC address of the device in network B, so a packet to this MAC address will be discarded by all devices in the network A (also by the router). Simply seen the router is just doing what I described above in the section How do IP addresses and MAC addresses work together. The router will receive packets for its own MAC address but for a different IP address. He will then check if he can directly reach the target IP address. Otherwise the router itself also has an upstream router configured and will send the packet to that router. They only allow access for known devices (MAC address is unique and identifies devices) with the correct passphrase.
