Switches store the MAC addresses in an internal database called MAC Address Table. The entries in that table can be addresses learned by the switch or that can be entered manually by the switch administrator. This table is analogy to a router's routing table, only a switch operates at layer 2 whereas the router operate at Layer 3.
What else can I help you with?
Where is the Mac address stored?
MAC address stored in NIC card
What happens if a MAC address is not stored in CAM on a switch?
Packets will be transmitted out of all switch ports except for the port where the packets were received. It's called flooding.
Which two statements describe the operation of an access layer ethernet switch choose two?
The source MAC address within a frame is used by the switch to associate a port with that MAC address. Frames are directed by the switch from one port to another based on the destination MAC address within the frame.
When would a switch record multiple entries for a single switch port in its MAC address table?
A switch would record multiple entries for a single switch port in its MAC address table if it does not contain the Mac address of a particular destination in the address table. It will broadcast to all ports besides the port where entry comes from.
Which criteria does the switch use to build dynamic Mac table?
address resolution protocol is used when the switch used to build the dynamic mac address table.
Does switch works on data link layer?
Switch working in Data link layer of OSI Model which is working my MAC address it is sending receiving packets by Mac address which switch make mac tale in RAM to save all information.
Which address does a switch use for implementing port security?
The source MAC address
What address does a switch use for implementing port security?
source mac address
What information in a frame does a switch or bridge use to populate the MAC address table?
Source MAC address and source port
Why does a switch flood a frame?
A switch floods a frame when it doesn't have the destination MAC address in its MAC address table. The frame is then forwarded out of all interfaces except the one it was received on in an attempt to find the correct host.
Does hub has Mac address?
No. Hubs simply repeat all the Ethernet frames on all ports and do not interfere with the source or destination MAC addresses and as such do not need their own MAC address.
Which device makes traffic forwarding decisions based on mac address?
A switch uses MAC address to forward frames while a router uses IP addresses.
