VE_Port class default settings
Table 19 provides default settings (per minute) for areas in the VE_Port class.
Packet loss monitoring enhancements on the VE_Port
Fabric Watch provides monitoring for packet loss percentage for the VE_Port. Previously,
configuring the packet loss percentage for the VE_Port was allowed as a whole number; however,
packet loss is usually found at less than one percent. Now there is support for configuring packet
loss percentages in decimals.
To set the high threshold for packet loss for a VE port, enter the portThConfig command using the
following parameters:
switch:admin> portthconfig --set ve-port -area PKTLOSS -highthreshold -value 0.60
-trigger above -action snmp
Port type: E_Port, FOP_Port, or FCU_Port
E_Port, FOP_Port, and FCU_Port guidelines represent a more aggressive approach in most areas
than physical port guidelines. Refer to “E_Port subclass setting guidelines” on page 63 and
“FOP_Port and FCU_Port subclass setting guidelines” on page 66 for configuration
recommendations.
Setting the port persistence time
Port persistence is used to transition a port into a marginal status. Fabric Watch does not record
the event until the event persists for a length of time equal to the port persistence time. If the port
returns to normal boundaries before the port persistence time elapses, Fabric Watch does not
record the event.
The port persistent time is measured in seconds and can be configured. Configuring the port
persistence time to zero disables this feature. The default value for port persistence is 18 seconds.
