30 seconds, with a default value of five seconds.
port−rx−utilization: This parameter defines the average percent utilization of the port resources for
all of the ports, by received data, as measured in five−minute intervals. This value ranges between
zero and one hundred, with a default value of 80. This threshold parameter can be disabled with the
no command.
• 
port−specific: This parameter defines the port−specific thresholds. When any individual port−specific
threshold is reached, the congestion control is applied system−wide. This is disabled by default for
each particular port number or for all of the ports for which the all keyword can be used. This
parameter has two sub−options that can be defined:
rx−utilization: The default value for this option is 80%. It measures the average percent
utilization of port resources for the specific port, by received data, as measured in
five−minute intervals. The values range between zero and one hundred.
♦ 
tx−utilization: The default value for this option is 80%. It measures the average percent
utilization of port resources for the specific port, by transmitted data, as measured in
five−minute intervals. The value ranges between one and one hundred.
♦ 
• 
port−tx−utilization: This parameter defines the average percent utilization of the port resources for all
of the ports, by transmitted data, as measured in five−minute intervals. This value ranges between
zero and one hundred, with a default value of 80. This threshold parameter can be disabled via the no
version of this command.
• 
service−control−cpu−utilization: This parameter defines the average percent utilization of CPUs on
which a DEMUX manager software task instance runs, as measured in ten−second intervals. This
value ranges between zero and one hundred, with a default value of 80.
• 
system−cpu−utilization: This parameter defines the average percent utilization for all PSC/PSC2
CPUs that are available to the system, as measured in ten−second intervals. This value ranges
between zero and one hundred, with a default value of 80. This can be disabled with no
congestion−control threshold system−cpu−utilization
 CLI command.
• 
system−memory−utilization: This parameter defines the average percent utilization for all of the CPU
memory that is available to the system, as measured in ten−second intervals. This value ranges
between zero and one hundred, with a default value of 80.
• 
Tolerance: This parameter defines the percentage under a configured threshold that dictates the point
at which the condition is cleared. This value ranges between zero and one hundred, with a default
value of ten. For example, if the threshold is configured with a value of 90 and the congestion control
is triggered, then the trigger is cleared at 80 if the default value of ten for the tolerance is defined.

Congestion Control Threshold Values for MME and SGSN
This section defines the configuration of the threshold for the MME and the SGSN when three different
triggers, along with congestion control profiles, are defined.
This information is applicable to MME Releases 14.0 and later, and SGSN Releases 17.0 and later. These are
the three different levels of triggers that are available for the MME and SGSN, which are further associated
with the congestion control policies that correspond:
Critical: This trigger level defines the critical threshold values for different parameters. The value of
this trigger level should be the largest among all three levels of thresholds. The critical thresholds
