Displaying the uptime for a switch

1. Connect to the switch and log in as admin.

2. Enter the uptime command.

ecp: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, and the load average
over the past one minute. The reason for the last switch reboot is also recorded in the system
message log.

Using the spinFab and portTest commands

The spinFab command is an online diagnostics command to verify the ISLs between switches at
the maximum speed. The routing functionality in the hardware must be set up so that the test
frames received by the E_Port are retransmitted on the same E_Port. Several frames are then sent
to the port attached to each active E_Port specified. These frames are special frames that never
occur during normal traffic, and the default action for such frames is to route them back to the
sender. These frames are circulated between switches until the test stops them.

CAUTION
During the spinFab testing, the switch remains in normal operation. However, some performance
degradation occurs due to the ISL links being saturated with the test frames. This test should be
run with caution on a live fabric.
