By default, TFTP transmits files in binary mode. 

To download a file, the client sends a request to the TFTP server and receives data 
from it, then sends acknowledgement to it. Use the following commands to

To upload a file, the client sends a request to the TFTP server and transmits data to 
it, then receives the acknowledgement from it. Use the following commands to

Perform the following configuration in system view.

The Switch 8800 maintains a MAC address table for fast forwarding of packets. A 
table entry includes the MAC address of a device and the port ID of the switch 
connected to it. The switch learns dynamic entries when it receives a data frame 
from a port (assumed as port A). The switch analyzes the source MAC address and 
considers that the packets destined for the source MAC address can be forwarded 
through port A. If the MAC address table contains the MAC_SOURCE, the switch 
updates the corresponding entry, otherwise, it adds the new MAC address (and 
the corresponding forwarding port) as a new entry to the table. 

The system forwards the packets whose destination addresses can be found in the 
MAC address table. The network device responds after receiving a broadcast 
packet and the response contains the MAC address of the device, which the 
switch learns and adds in the MAC address table. After this, subsequent packets 
destined for the same MAC address can be forwarded directly.
