Describe how a switch learns addresses?
A switch examines the frame for the MAC address information and adds it to its internal switching table as each frame passes through the switch.
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.
Why does the switch between Host and the router not require configuration with an IP address to forward packets?
If a switch is connected to a router then the MAC address of the router is known to the switch through that port. A host takes advantage of this by using the default gateway address (the address of the router) which the switch "knows" by its lookup table. Therefore, the switch can learn the address automatically and no configuration is necessary.
How do you assign IP to cisco switch?
You can't assign an ip to a switch but you can add one to the interfaces......... like: for the management vlan (or any other vlan) Switch(config)#int vlan 1 Switch(config-if)#ip address {your ip address} {mask} Switch(config-if)#no shutdown any other port Switch(config)#int <fa, G, S> <interface number i.e. 0/0> Switch(config-if)#ip address {your ip address} {mask} Switch(config-if)#no shutdown and for a default gateway Switch#conf t Switch(config)#ip default-gateway {ip address}
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.
Does switch understand internet protocol?
yes switch work on ip address.
Why does a switch need an IP address?
It doesn't necessarily need and IP. Depends on whether it is a managed or unmanaged switch. For instance your switch would need an IP address in order to telnet to it.
What describe a connection to a switch port?
it so about there are go
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 is the purpose of assigning an IP address to a Layer 2 switch?
A layer 2 switch may need an IP address if the operator wishes to be able to access it without a serial cable. With an IP address, the switch can be access from anywhere with a connection to the network or an Internet connection.
What address does a switch build into its table to successfully send data to that device?
A switch builds a MAC address table, which contains the MAC addresses of devices connected to its ports along with the corresponding port numbers. When a switch receives a data frame, it reads the source MAC address and updates its table if the address is not already present. To send data to a specific device, the switch looks up the destination MAC address in its table and forwards the frame out of the appropriate port associated with that address. If the destination address is not found, the switch broadcasts the frame to all ports except the one it received it on.
