Confirming the Installation

This section describes procedures used to confirm that the hardware and software installation and configuration procedures were successful. The following procedures are discussed:

  • Using the module LEDs

  • Using the ping Command

  • Using the show system Command

  • Using the show config Command

  • Using the show port Command

Using the Module LEDs

This section describes the LEDs used to confirm and troubleshoot operation of the Catalyst 2900 modules. The LEDs on the supervisor engine module indicate the system power and processor status; LEDs on the switching modules indicate the status of the individual switching module and their interfaces.

Status LEDs

When the Catalyst 2900 is plugged in it runs a series of diagnostic tests. During this period, the status LED is orange. If the switch passes all the tests, the status LED is green. If any tests fail, the status LED turns red. The status LED will also be orange when it is explicitly disabled with the system software.

Supervisor Engine Module LEDs

The LEDs on the supervisor engine module reflect how the system's various components are operating and are described in Table 7-1. For a description of the power supply shutdown conditions and threshold status levels, refer to the section "Environmental Monitoring" in the chapter "What Is the Catalyst 2900?."

The supervisor engine module LEDs are shown in Figure 7-1.


Figure 7-1: Supervisor Engine Module LEDs




Table  7-1: Supervisor Engine Module LEDs
LED Description
Status The switch performs a series of self-tests and diagnostic tests.
If all the tests pass, the status LED is green.
If any test fails, the status LED is red.
During system boot or if the module is disabled, the LED is orange.
Fan Indicates whether or not the fans are operational.
If the fans are operational, the fan LED is green.
If the fans are not operational, the fan LED is red.
PS If the power supply is operational, the PS LED is green.
If the power supply detects an anomaly, the PS LED is red.
100 Mbps Green--Indicates that the port is operating at 100 Mbps.
Link Green--The port is operational.
Orange--The link has been disabled by software.
Orange flashing--The link is bad and has been disabled.
Off--No signal is detected.

Switch Load Meter

The switch load-meter LEDs provide a visual indication (as an approximate percentage) of the current traffic load over the backplane. (See Figure 7-2.)


Figure 7-2: Switch Load LED



10/100BaseTX LEDs

The LEDs provide status information for the module and individual 10/100 Mbps Fast Ethernet interface connections. The LEDs are shown in Figure 7-3 and described in Table 7-3.


Figure 7-3: 10/100 Mbps Fast Ethernet Switching Module LEDs




Table  7-2: 10/100 Mbps Fast Ethernet Module LED Descriptions
LED Description
Status The switch performs a series of self-tests and diagnostic tests.
If all the tests pass, the Status LED is green.
If any test fails, the Status LED is red (or orange for a minor fault).
During system boot or if the module is disabled, the LED is orange.
During self-test diagnostics, the LED will be orange.
If the module is disabled, the LED will be orange.
100-Mbps Green --Indicates that the port is operating at 100-mbps.
Link (bottom LED) Green --Indicates the port is operational (signal detected).
Orange--Link disabled by software.
Orange flashing--Port bad and disabled (hardware failure).
Off--No signal detected.

100BaseFX 12 Port LEDs

The LEDs on the faceplate of the Fast Ethernet switching module (100BaseFX 12 port), shown in Figure 7-4, are described in Table 7-3.


Figure 7-4: 100BaseFX LEDs




Table  7-3: 100BaseFX LED Descriptions
LED Description
Status The switch performs a series of self-tests and diagnostic tests.
If all the tests pass, the status LED is green.
If any test fails, the status LED is red (or orange for a minor fault or if manually disabled).
Link Green--the port is operational.
Orange--the link has been disabled by software.
Orange flashing--the link is bad and has been disabled.
Off--no signal is detected.

Using the ping Command

Enter the ping command to send Internet Control Message Protocol (ICMP) echo request packets to another node on the network to confirm the connection to that node.

ping -s host [packet_size] [packet_count]
Syntax Description
-s Causes ping to send one datagram per second, printing one line of output for every response received. The ping command does not return any output when no response is received.
host The IP address or IP alias of the host.
packet_size (Optional) The number of bytes in a packet, from 1 to 2,000 bytes, with a default of 56 bytes. The actual packet size is eight bytes larger because the switch adds header information.
packet_count (Optional) The number of packets to send.
Usage Guidelines

Enter Ctrl-C to stop pinging.

Following are sample results of the ping command:

  • Normal response--The normal response occurs in one to ten seconds, depending on network traffic.

  • Destination does not respond--If the host does not respond, a no answer message appears in ten seconds.

  • Destination unreachable--The gateway given in the route table for this destination indicates that the destination is unreachable.

  • Network or host unreachable--The switch found no corresponding entry in the route table.

Example

In the following example, a host with IP alias elvis is pinged a single time, then pinged once per second until Ctrl-C is entered to stop pinging:

Console> ping elvis
elvis is alive
Console> ping -s elvis
ping elvis: 56 data bytes
64 bytes from elvis: icmp_seq=0. time=11 ms
64 bytes from elvis: icmp_seq=1. time=8 ms
64 bytes from elvis: icmp_seq=2. time=8 ms
64 bytes from elvis: icmp_seq=3. time=7 ms
64 bytes from elvis: icmp_seq=4. time=11 ms
64 bytes from elvis: icmp_seq=5. time=7 ms
64 bytes from elvis: icmp_seq=6. time=7 ms

Using the show system Command

Enter the show system command to display the power supply, fan, temperature alarm, system, and modem status; the number of days, hours, minutes, and seconds since the last system restart; the baud rate; the MAC address range; and the system name, location, and contact.

Example

In the following example, the system status and other information is displayed:
