TFTP is part of the Internet Protocol Suite defined in RFC 1350. The protocol operates on top of theUDP (User Datagram Protocol)to transfer files from one end to the other. It uses the well-known port 69 for requests. The protocol typically reads or writes data to theserver. However, i...
TFTP runs over UDP (User Datagram Protocol) and uses port 69. It's quite old but not nearly as old as FTP. First introduced in 1980 via IEN (Internet Experimental Note) 133, it was eventually defined the following year in RFC 783. The TFTP we know now is based on RFC 1350, which ...

Generally, TFTP is of four types which are- Read request Write request Data Packets Acknowledgement request Advantages of TFTP Uses UDP protocol It is easier to implement Requires less coding Less memory usage Why Should We Use TFTP and Why do we Need TFTP ...
FTP supports different data transfer modes, including active and passive, to navigate various network configurations and firewall restrictions. While active mode requires the client to open a port for the server to connect, passive mode allows the client to initiate all connections, making it morefi...
1. On the router, download ova file via tftp: Router#copy tftp flash Address or name of remote host []? 172.1.1.2 Source filename []? vm1.ova Destination filename [vm1.ova]? 2. Install / unisntall the VM: Router#virtual-service install name vm1 package flash:/vm1.ova ...
If the protocol types, source IP address ranges, and destination IP address ranges are the same, the rule that defines the smallest Layer 4 port number (TCP/UDP port number) range is processed. If the preceding ranges are all the same, the rule with the smallest ID is processed. ...

As a result, SNMP uses the UDP port 161 of the SNMP Agent for sending and receiving requests. On the other hand, SNMP uses also port 162 of the SNMP Manager for receiving traps from managed devices. To conclude, every device that implements SNMP must use these port numbers as the default...
