Fcs layer 2

WebMAC address (Layer 2 addresses, physical address or hardware address) is a universally unique identifier, permanently burned in the network card/interface. For Ethernet and Token Ring, these addresses are 48 bits, or six octets (bytes). WebDec 8, 2010 · Frame Check Sequence (FCS) Errors, a type of CRC, indicate that frames received by an interface are an integral number of octets long but do not pass the FCS check. The FCS is a mathematical way to ensure that all the frame's bits are correct without having the system examine each bit and compare it to the original.
