What field in an Ethernet frame does a switch use to determine where to send a frame? The
Destination MAC address.
What field in an Ethernet frame does a switch use to learn MAC addresses? The Source MAC
address.
What does a switch do when it receives a frame with a destination MAC address that is not in
the MAC address table? It floods the frame out all ports in the same VLAN except the one it
was received on.
What are the three possible actions a switch can take when processing a frame? Forward,
Flood, Discard.
What is dynamic MAC address learning? The process where a switch learns the source MAC
address of a frame and associates it with the ingress port and VLAN.
What is the default MAC aging timer on Cisco switches? 300 seconds.
How can you manually add a static MAC address on a Cisco switch? mac address-table static
<mac> vlan <vlan-id> interface <intf>
What command shows all MAC addresses the switch has learned? show mac address-table
What command displays the number of dynamic and static MAC addresses in the table?
show mac address-table count
Which MAC address type has priority if both static and dynamic entries exist? Static MAC
address entry.
, What causes a switch to discard a frame? Frame is too small (runt), too large, has bad FCS,
or is blocked by an ACL or VLAN mismatch.
What does it mean when a switch floods a frame? It sends the frame out all ports in the
same VLAN except the port it arrived on.
Do switches ever send a frame back out the same port it arrived on? No, switches do not
hairpin frames.
