I am using Cisco Works Version 4.0.5. I used NetConfig jobs to run automatic jobs on Cisco Switches and other devices on my network. I get about a 50% failure rate on every job. 150 devices take the job and 150 devices fail. I get the error: &quot;ERROR:RME_CDL1031:Transpo<wbr />rt session to device failed T<a href="FTP" rel="ugc">FTP</a>: Failed on the device. SSH: Failed to establish SSH connection to x.x.x.x - Cause: Authentication failed on device 3 times.&quot; But I can SSH or telnet to these devices outside of Cisco Works. Does anyone have any idea how to fix this? Thanks. &nbsp;

NetConfig jobs failing on network devices

I am using Cisco Works Version 4.0.5. I used NetConfig jobs to run automatic jobs on Cisco Switches and other devices on my network. I get about a 50% failure rate on every job. 150 devices take the job and 150 devices fail. I get the error: &quot;ERROR:RME_CDL1031:Transport session to device failed TFTP: Failed on the device.

Telnet is an application layer protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. SSH was designed as a replacement for Telnet and for unsecured remote shell protocols. The term telnet is also used to refer to the software that implements the client part of the protocol. SSH provides a secure channel over an unsecured network in a client-server architecture, connecting an SSH client application with an SSH server.

Network analysis is the process of identifying and remediating the processes and systems within a network, including performance, connectivity and security. The process is performed through the use of tools developed for monitoring and analyzing network activity. Network problems that involve finding an optimal way of doing something are studied under the name combinatorial optimization. Examples include network flow, shortest path problem, transport problem, transshipment problem, location problem, matching problem, assignment problem, packing problem, routing problem, Critical Path Analysis and PERT (Program Evaluation & Review Technique).

Network Analysis

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
