Getting Information About Remote Devices
Objectives
Upon completing this lesson, you will be able to:
Use Telnet to connect to remote network devices, given operational access layer switches and routers
Use IOS commands to manage the Telnet sessions, given operational access layer switches and routers
Using Telnet to Connect to Remote Devices
Viewing Telnet Connections
Suspending and Resuming
a Telnet Session
Closing a Telnet Session
Using the ping and trace Commands
Tests the connectivity and path to a remote device
Router###ping 10.1.1.10
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.10, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/4/4 ms
Router#trace 192.168.101.101
Type escape sequence to abort.
Tracing the route to 192.168.101.101
1 p1r1 (192.168.1.49) 20 msec 16 msec 16 msec
2 p1r2 (192.168.1.18) 48 msec * 44 msec
Router#
Summary
The Telnet application is useful for obtaining information about remote devices that aren’t
accessible by CDP.
Once connected to a remote device, you may want to access your local device without terminating the Telnet session. Telnet allows you to temporarily suspend and then resume a remote session.
You can end a Telnet session on a Cisco device using the exit, logout, disconnect, or clear command.
The ping and trace commands provide information about the connectivity with and path to remote devices.
