Configuring a Physical Interface Threshold

To configure the physical interface threshold, enter the following command:

What to Do Next

Choose one of the following:

See the

“Using SNMP Version 1 or 2c” section on page 79-22

.

See the

“Using SNMP Version 3” section on page 79-23

Command

Purpose

snmp cpu threshold rising

threshold_value monitoring_period

Example:

hostname(config)# snmp cpu threshold

rising 75% 30 minutes

Configures the threshold value for a high CPU threshold and the threshold
monitoring period. To clear the threshold value and monitoring period of the
CPU utilization, use the no form of this command. If the snmp cpu threshold
rising
command is not configured, the default for the high threshold level is
over 70 percent, and the default for the critical threshold level is over 95 percent.
The default monitoring period is set to 1 minute.

You cannot configure the critical CPU threshold level, which is maintained at a
constant 95 percent. Valid threshold values for a high CPU threshold range from
10 to 94 percent. Valid values for the monitoring period range from 1 to 60
minutes.

Command

Purpose

snmp interface threshold

threshold_value

Example:

hostname(config)# snmp interface

threshold 75%

Note

Not supported on the
ASA Services Module.

Configures the threshold value for an SNMP physical interface. To clear the
threshold value for an SNMP physical interface, use the no form of this
command. The threshold value is defined as a percentage of interface bandwidth
utilization. Valid threshold values range from 30 to 99 percent. The default
value is 70 percent.

The snmp interface threshold command is available only in the admin context.

Note

Physical interface usage is monitored in single mode and multimode,
and traps for physical interfaces in the system context are sent through
the admin context. Only physical interfaces are used to compute
threshold usage.
