Checking the Interface Configuration
After configuring the new interface, you can perform the following tests to verify
that the new interface is operating correctly:
• Display the Catalyst 4224 hardware configuration with the show version
command. Check that the list includes the new interface.
• Specify an interface with the show interfaces [type slot/port] command and
verify that the first line of the display shows the interface with the correct slot
and port number, and that the interface and line protocol are in the correct
state, up or down.
• Display the protocols configured for the entire Catalyst 4224 and for
individual interfaces with the show protocols command. If necessary, return
to configuration mode to add or remove protocol routing on the Catalyst 4224
or its interfaces.
• Display the running configuration with the show running-config command,
and the configuration stored in NVRAM using the show startup-config
command.
• Use the ping command to send an echo request to a specified IP address. Each
returned signal is displayed as an exclamation point (!) on the console; each
signal that is not returned before the timeout is displayed as a period (.). A
series of exclamation points (!!!!!) indicates a good connection; a series of
periods (.....) or the messages “timed out” or “failed” indicate that the
connection failed.
If an interface is down and you configured it as up, or if the displays indicate that
the hardware is not functioning properly, make sure that the new interface is
properly connected and configured.
