TFTP support with Ethernet WAN interface
TFTP support with Ethernet WAN interface
Trivial File Transfer Protocol (TFTP) is a file transfer protocol notable for its simplicity. It is generally used for automated transfer of configuration or boot files between machines in a local environment.
The Cisco 819H ISR supports TFTP with Ethernet WAN interface that supports data transfer rate of 10 Mbps.
For more information, see the “Using the TFTP Download Command” section on page
Note This feature is supported in all Cisco 819 ISRs that have ROMMON version 15.2(2r)T and above.
Note TFTP download using switch port is supported in Cisco 819HGW SKUs only.
