and no greater than 1. The default value is 0.8. Note that the application of the
sub-second numerical limits is approximate. This command erases the statistics
history and restarts alert calculations (if alerting is enabled) on the specified ports.
When used with the config option, you must specify a port.
-lsubsecsevthresh severity_threshold
Specifies the threshold on the severity of latency in terms of the throughput loss
on the port at the sub-second level. The severity threshold is a floating-point value
in the range of no less than 1 and no greater than 1000. This value specifies the
factor by which throughput must drop in a second in order for that second to be
considered affected by latency bottlenecking. For example, a value of 20 means
that the observed throughput in a second must be no more than 1/20th the
capacity of the port in order for that second to be counted as an affected second.
The default value is 50. This command erases the statistics history and restarts
alert calculations (if alerting is enabled) on the specified ports. When used with the
config option, you must specify a port.
Excludes the specified ports from bottleneck detection. No data will be collected
from these ports, and no alerts will be triggered for these ports. All statistics
history for a port is erased when a port is excluded. Alerting parameters are
preserved. It is not recommended to exclude ports from monitoring except under
special circumstances, for example, when a long-distance port is known to be a
bottleneck because of credit insufficiency. The wildcard (*) port specifier is allowed
but not recommended. Use --disable to exclude all ports on the switch.
Includes previously excluded ports for bottleneck detection. Previously configured
switch-wide alerts and threshold parameters reapply when bottleneck detection
resumes. The wildcard (*) port specifier may be used as a shorthand for removing
all exclusions.
Removes any port-specific alert parameters from the specified ports and restores
switch-wide parameters on these ports. You can still view the history of
bottlenecks statistics on these ports. However, alert calculations restart on the
specified ports after the parameter reset. This operation is allowed on excluded
ports.
Disables bottleneck detection on the entire switch. This operation erases all
configuration details, including the list of excluded ports, all custom thresholds and
alerting parameters for specific ports, and all historical data.
Displays a history of the bottleneck severity for the specified ports. The output
shows the percentage of one-second intervals affected by the bottleneck condition
within the specified time interval. When a single port is specified, the command
displays the bottleneck statistic for that port. When the wildcard (*) is specified, the
same statistic is displayed for every port on the switch. Additionally, a combined
"union" statistic for the switch as a whole is displayed. When used without a port
specifier, the command displays the number of ports affected by bottleneck
conditions. A "bottlenecked" port in this output is defined as any port that was
affected by a bottleneck for one second or more in the corresponding interval.
This command succeeds only on online ports.
