Unplug and plug in the power cord (power cycling).

Press the Reset button on the front of the switch.

Reboot the switch via the management console's boot system command.

Power cycling the switch and pressing the Reset button both cause the switch to perform its power-on self test,

which almost always will resolve any temporary operational problems. These reset processes also cause any

network traffic counters to be reset to zero, and cause the System Up Time timer to reset to zero.

Checking the switch LEDs

See

Switch and port LEDs on front of the switches

behaviors.

Checking console messages

Useful diagnostic messages may be displayed on the console screen when you reset a switch. Connect a PC running

a VT-100 terminal emulator program or a standard VT-100 terminal to the switch console port. Configure the

terminal to run at 115200 baud, and with the other terminal communication settings.

When you reset the switch, note the messages that are displayed. Additionally, you can check the switch event log,

which can be accessed from the console using the show log command, or from the console main menu.

Testing twisted-pair cabling

Network cables that fail to provide a link or provide an unreliable link between the switch and the connected network

device may not be compatible with the IEEE 802.3 Type 10Base-T, 100Base-TX, or 1000Base-T standards. The

twisted-pair cables attached to the switch must be compatible with the appropriate standards. To verify your cable

is compatible with these standards, use a qualified cable test device.

Testing switch-to-device network communications

The following communication tests can verify that the network is operating correctly between the switch and any

connected device that can respond correctly to the communication test.

Link Test: A physical layer test that sends IEEE 802.2 test packets to any device identified by its MAC address.

Ping Test: A network layer test used on IP networks that sends test packets to any device identified by its IP

address.

These tests can be performed through the switch console interface. Use a terminal connected directly to the switch

or through a Telnet connection, or from the switch web browser interface. For more information, see the

Fundamentals Guide for your switch.

These tests can also be performed from an SNMP network management station running a program that can

manage the switch, like AirWave.

Testing end-to-end network communications

Both the switch and the cabling can be tested by running an end-to-end communications test. This is a test that

sends known data from one network device to another through the switch. For example, if you have two PCs on the

network that have LAN adapters between which you can run a link-level test or Ping test through the switch, you can

use this test to verify that the entire communication path between the two PCs is functioning correctly. See your LAN

adapter documentation for more information on running a link test or Ping test.
