Port Utilization
Thresholds
Threshold monitoring
can be enabled for the port utilization values described in the
following table.
Value |
Description |
To
configure, go to section: |
Receive
port utilization |
Enables
the generation of alerts or alarms based on the port utilization
percentage for data received during the polling interval. |
Receive Port Utilization Thresholds |
Transmit
port utilization |
Enables
the generation of alerts or alarms based on the port utilization
percentage for data transmitted during the polling interval. |
Transmit Port Utilization Thresholds |
High
port activity |
Enables
the generation of alerts or alarms based on the overall port utilization
percentage during the polling interval. |
High Port Activity Thresholds |
IMPORTANT:
Ports configured for
half-duplex do not differentiate between data received and data transmitted.
(The transmitted and received percentages are combined.) Therefore,
to avoid redundant alarms, it is recommended that only the receive or transmit utilization
threshold be configured.
Saving Your Configuration
When you configure
thresholds they are not permanent unless you save the changes. When you
have completed configuring thresholds, save your configuration to
flash memory, an external memory device, and/or a network
location using the Exec mode command save configuration.
For additional information on how to verify and save configuration
files, refer to the System Administration Guide and the Command
Line Interface Reference.
Receive Port Utilization
Thresholds
Receive port
utilization thresholds generate alerts or alarms based on the utilization
percentage of each configured port in relation to data received
during the specified polling interval. This threshold is configured
on a per-port basis.
Alerts or alarms are
triggered for receive port utilization based on the following rules:
- Enter condition: Actual
percent utilization of a port for received data > or = High
Threshold
- Clear condition: Actual
percent utilization of a port for received data < Low Threshold
If a trigger condition
occurs within the polling interval, the alert or alarm will not
be generated until the end of the polling interval.
Configuring Receive
Port Utilization Thresholds
Use the following
example to configure the polling interval over which to measure
receive port utilization
configure
threshold poll port-rx-utilization
interval <seconds>
port <port-type> <slot#/port#>
threshold rx-utilization <high_thresh_%> [ clear <low_thresh_%> ]
threshold monitoring
end
Transmit Port Utilization
Thresholds
Transmit port
utilization thresholds generate alerts or alarms based on the utilization
percentage of each configured port in relation to data transmitted
during the specified polling interval. This threshold is configured
on a per-port basis.
Alerts or alarms are
triggered for transmit port utilization based on the following rules:
- Enter condition: Actual
percent utilization of a port for transmit data > or = High
Threshold
- Clear condition: Actual
percent utilization of a port for transmit data < Low Threshold
If a trigger condition
occurs within the polling interval, the alert or alarm will not
be generated until the end of the polling interval.
Configuring Transmit
Port Utilization Thresholds
Use the following
example to configure the polling interval over which to measure
transmit port utilization:
configure
threshold poll port-tx-utilization
interval <seconds>
port <port-type> <slot#/port#>
threshold tx-utilization <high_thresh_%> [ clear <low_thresh_%> ]
threshold monitoring
end
High Port Activity
Thresholds
High port activity
thresholds generate alerts or alarms based on the peak utilization
percentage of each configured port during the specified polling
interval. This threshold is configured on a per-port basis.
Alerts or alarms are
triggered for high port activity based on the following rules:
- Enter condition: Actual
percent peak utilization of a port > or = High Threshold
- Clear condition: Actual
percent peak utilization of a port < Low Threshold
If a trigger condition
occurs within the polling interval, the alert or alarm will not
be generated until the end of the polling interval.
Configuring High
Port Activity Thresholds
Use the following
example to configure the polling interval over which to measure
for high port activity:
configure
threshold poll port-high-activity
interval <time>
port <port-type> <slot#/port#>
threshold high-activity <high_thresh_%> [ clear <low_thresh_%> ]
threshold monitoring
