Configure the file transmission mode
TFTP transmits files in two modes; binary mode for program files and ASCII mode
for text files. You can use the following commands to configure the file
transmission mode.
Perform the following configuration in system view.
By default, TFTP transmits files in binary mode.
Download Files by means of TFTP
To download a file, the client sends a request to the TFTP server and then receives
data from it and sends acknowledgement to it. You can use the following

Upload Files by means of TFTP
To upload a file, the client sends a request to the TFTP server and then transmits
data to it and receives the acknowledgement from it. You can use the following

MAC Address Table
Management
The Switch 7700 maintains a MAC address table for fast forwarding packets. A
table entry includes the MAC address of a device and the port ID of the Ethernet
switch connected to it. The dynamic entries (not configured manually) are learned
by the Ethernet switch. The Ethernet switch learns a MAC address in the following
way: after receiving a data frame from a port (assumed as port A), the switch
analyzes its source MAC address (assumed as MAC_SOURCE) and considers that
the packets destined at MAC_SOURCE can be forwarded via the port A. If the
MAC address table contains the MAC_SOURCE, the switch will update the
corresponding entry, otherwise, it will add 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 directly through the hardware and broadcasts. The network
device responds after receiving a broadcast packet and the response contains the
