command in top mode.

4.1.5 Test Connections with Ping Tests
The switch supports IP ping, which can be used to test connectivity to remote hosts, via their IP addresses.
Ping sends an echo request packet to an address and “listens” for a reply. The ping request will receive one
of the following responses:
• Normal response—The normal response occurs in 1 to 10 seconds, depending on network traffic
• Request timed out—There is no response, indicating a connection failure to the host, or the host
has discarded the ping request
Beginning in privileged EXEC mode, use this command to ping another device on the network
from the switch:
Command Purposes
ping address
Send an ICMP echo message to a designated host for testing
connectivity.
4.1.6 Enable the System Log
The IC35516 can send syslog messages to manager servers. Syslog messages are collected by a standard
UNIX or NT type syslog daemon.
Syslog enables the administrator to centrally log and analyze configuration events and system error
messages such as interface status, security alerts, environmental conditions, and CPU process overloads.
To log messages, use the following command in global configuration mode.
Command Purpose
logging
address
IP address of the host to be used as a syslog server.
logging facility
Facility parameters for syslog messages.
logging trap
Set syslog server logging level.
4.1.7 Displaying the Operating Configuration
The configuration file may be displayed from the EXEC (enable) mode.
To see the current operating configuration, enter the following command at the enable prompt:
Router# show running-config
To see the configuration in NVRAM, enter the following command:
Router# show startup-config
If you made changes to the configuration, but did not yet write the changes to NVRAM, the results of the
show running-config will differ from the results of the show startup-config command.
