Configuring MAC address for specific port

[mohan4]

Hi 

 i am using C3850-12s- switch . My question is if i am using a converter in between a Two Cisco switches  Switch A and Switch B . i am Securing the Specific port of two switches using MAC id of that two Specific Ports on either side. Will it still communicate through the Two  converter ( consider Media converter ) . Eg : Switch A (Port1)---> converter A---> converterB---> switch B(port1)

Yes, if your media converter is unmanaged, it's practically a layer 1 device so totally transparent to the switches.

Hello Mohanvenkatram,

Configuring MAC address for specific port

Layer 2 is the Data-Link Layer. Devices operating at Layer 2 sort packets using physical network addresses, also known as MAC addresses. All network hardware is permanently assigned this number during its manufacture.

Both switches and media converters can be Layer 2 devices. Usually the only difference between a Layer 2 switch and a Layer 2 media converter is the number of ports—a device with two or three ports is called a media converter; four or more ports is called a switch. A media converter operating at Layer 2 may have more than two ports and may have ports operating at different speeds.

Devices operating at Layer 2 are very fast, but aren’t very smart because they don’t look at data packets closely. A Layer 2 media converter is considered to be fairly advanced for a media converter, but a Layer 2 switch is a basic switch.
