The switchShow command also displays the following information for ports on the specified
switch:
The details displayed for each switch differ on different switch models. For more information see
the switchShow command in the Fabric OS Command Reference.
Displaying the uptime for a switch
1. Connect to the switch and log in as admin.
2. Enter the uptime command:
supp_dcx_184:admin> uptime
10:50:19 up 11 days, 6:28, 1 user, load average: 0.49, 0.53, 0.54
The uptime command displays the length of time the system has been in operation, the total
cumulative amount of uptime since the system was first powered-on, the date and time of the
last reboot (applies only to Fabric OS v3.x systems), the reason for the last reboot (applies only
to Fabric OS v3.x systems), and the load average over the past one minute (1.29 in the
preceding example), five minutes (1.31 in the example), and 15 minutes (1.27 in the example).
The reason for the last switch reboot is also recorded in the system message log.
Chassis-level diagnostics
In the non-Virtual Fabric platforms, there are no changes to the existing support of diagnostics.
However, in Virtual Fabric supported platforms, you must use the commands chassisDisable and
chassisEnable to disable all the ports in the chassis before executing offline diagnostics. For
example, with chassis-level diagnostics such as systemVerification, the chassisDisable command
must be entered before running the test. For blade-level diagnostics such as portLoopbackTest, the
bladeDisable command must be entered before running the test. The following lists commands to
use when diagnosing chassis problems:
• chassisDisable — disables all the ports in the chassis
Area Part of the 24-bit port ID, which consists of domain, port area number, and
optional AL_PA. Area column is only displayed on non-modular platforms.
Index Index follows Area up to 255. Then it continues to the maximum port of the
platform. Index identifies the port number relative to the switch. Index column
is only displayed on enterprise-class platforms.
Slot Slot number; 1-4 and 7-10.
Port Port number; 0-15, 0-31 or 0-47.
Address The 24-bit Address Identifier. Address column is only displayed on
enterprise-class platforms.
Media SFP types used.
Speed The speed of the Port (1G, 2G, 4G, 8G, 10G, N1, N2, N4, N8, AN, UN). The
speed can be fixed, negotiated, or auto-negotiated.
State The port status.
Proto Protocol support by GbE port.
Comment Information about the port. This section may be blank or display the WWN for
an F_Port or an E_Port, the trunking state, or upstream or downstream status.
