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
