To direct output to the serial port, follow these steps:
Step 1 Log in to the CLI using an account with administrator privileges.
Step 2 Direct the output to the serial port:
sensor# configure terminal
sensor(config)# display-serial
The default is not to direct the output to a serial connection.
Reset the output to the local console:
Step 3
sensor(config)# no display-serial
Diagnosing Network Connectivity
Use the ping ip-address [count] command to diagnose basic network connectivity.
Caution No command interrupt is available for this command. It must run to completion.
To diagnose basic network connectivity, follow these steps:
Log in to the CLI.
Step 1
Ping the address you are interested in:
Step 2
sensor# ping ip-address count
The count is the number of echo requests to send. If you do not specify a number, 4 requests are sent.
The range is 1 to 10,000.
Example of a successful ping:
sensor# ping 10.89.146.110 6
