Configuring and Testing Your Network : Configuring and Testing Your Network Network Fundamentals – Chapter 11 – Part B
Objectives : Objectives Define the role of the Internetwork Operating System (IOS)
Use Cisco CLI commands to perform basic router and switch configuration and verification
Given a network addressing scheme, select, apply, and verify appropriate addressing parameters to a host
Use common utilities to verify network connectivity between hosts
Use common utilities to establish a relative performance baseline for the network
Tools for Archiving Device Configuration : Tools for Archiving Device Configuration Use basic IOS config commands to manage a device
Capture output of session toa text file
Copy configuration to a TFTP server
Setting Up the TFTP Server : Setting Up the TFTP Server Free Trivial FTP products are available
Classroom use: Solarwinds TFTP
Protocol: UDP Port: 69
Test connectivity with PING before attempting TFTP
To restore an IOS image, reverse the copy process:
Router#copy TFTP flash
Note: a Cisco router can also function as a TFTP server and allow copying of IOS from device to device
Configuring an IP Address in Windows : Configuring an IP Address in Windows What steps are needed to setup an IP address on a host? IPCONFIG - Windows
IFCONFIG - Linux
Configuring the Correct Host Parameters : Configuring the Correct Host Parameters Identify two ways parameters (IP address) can be assigned to hosts
Besides the IP/Subnet Mask, what needs to be configured for Inter-network communication?
Testing with PING : Testing with PING Use the ping command in the CLI to determine if the IP protocol is operational on a local host
Extended PING in Cisco IOS : Extended PING in Cisco IOS Allows selection of variables for troubleshooting
Initiated by typing PING with no keywords or IP address
Router#ping
Protocol [ip]:
Target IP address:10.0.0.1
Repeat count [5]:
Datagram size [100]:
Timeout in seconds [2]:5
Extended commands [n]: n
Network Testing that Fails : Network Testing that Fails Identify several conditions that might cause the test to fail
Network Baselines with Common utilities : Network Baselines with Common utilities Use the output of the ping or Trace Route
Save into logs and repeat over time FreePING
Verify Physical Addresses of Hosts : Verify Physical Addresses of Hosts Use the ARP command to display cached MAC addresses Show mac-address-table
