Using the nosave command

The nosave command prevents the configuration changes from being saved persistently. This
option allows you to make and view changes without overwriting the saved configuration.
CAUTION
When you use --set with the --nosave option and the switch reboots, your changes are lost.

portThConfig command procedures

The following sections provides specific examples for the Port class. See
default settings"
E_Port, the FOP_Port, and the FCU_Port.

Port type: physical port

The Port class is a superset containing the E_Port, FOP_Port, and FCU_Port subclasses. In general,
use the default settings listed in
settings are common to one or more of the port subclasses; for example, configuring all physical
ports to monitor invalid CRC counts. In most cases, the default settings are adequate for the
physical port.
Configuring all physical ports to monitor invalid CRC counts
Invalid Cyclic Redundancy Check (CRC) count errors on a port can represent noise on the network
or a potential hardware problem.
1. Enter the portThConfig command using the following parameters:

switch:admin> portthconfig
-trigger above -action raslog,email,snmp -buffer 0
switch:admin> portthconfig
above -action raslog -buffer 0
•
In this example, the alarms are set at two points: a low threshold of 1 and a high threshold
of 100 (the default is 1000). The goal is to be notified as the number of invalid CRCs per
minute rises above the low boundary and again when it rises above the high boundary.
•
Triggers specify actions for below the high threshold. Here, the trigger for both is above.
•
Set the action to take when a trigger occurs. Here, for the high threshold, log the event in
the raslog, send an e-mail, and issue an SNMP trap. For the low threshold, only log the
event in the raslog.
•
Set the buffer setting to 0 (the default is 100). Note that if you do not specify the buffer
value, Fabric Watch automatically re-calculates the buffer.
•
Apply the new custom settings so they become effective.
