How the Switch Reports Problems
The switch detects and processes errors as follows:
# The LEDs indicate problems with the ports and power. For
information on the LEDs, refer to ‘Switch LEDs’ on page 41.
# In a TCP/IP environment, if you have configured the software
correctly, the management software triggers an SNMP trap
message. As a result, the software then sends traps to alert the
network manager when a trigger occurs. This type of software
configuration allows the network administrator to proactively
monitor the network.
