With the modified
policy
keyword, the operator associates the SGSN’s congestion-response action-profile with each
of 3 possible levels of congestion - critical, major, and minor.
configure
congestion-control policy { critical | major | minor } sgsn-service action-profile
action_profile_name
action_profile_name
no congestion-control policy { critical | major | minor } sgsn-service
end
Notes:
no
: Removes the configured congestion-control policy information.
critical | major | minor
: Identifies the level of congestion to associate with a congestion-control
response policy. The threshold levels for critical, major and minor congestion levels are all set using the
congestion-control threshold
.
sgsn-service
: Identifies the StarOS service type; in this case, the SGSN (Gn-SGSN and/or S4-SGSN).
action_profile_name
: Enter a string of 1 to 64 alphanumeric characters to identify the congestion-action-
profile to associate with the congestion-control policy. Refer to the
congestion-action-profile
command in the SGSN-Global Configuration mode to create or review the congestion-action-profiles which
define the congestion response actions to be taken when thresholds are exceeded for the SGSN.
define the congestion response actions to be taken when thresholds are exceeded for the SGSN.
This command can be repeated to associate a congestion-action-profile for each level of congestion severity:
critical, major, minor.
Use the
show congestion-control configuration
command to display the SGSN’s congestion-control
policy with the congestion-action-profile names association with the level of congestion severity; for example:
sgsn-service:
Critical Action-profile : actprof1
congestion-control
New configuration command in the SGSN-Global configuration mode define congestion control practices for the SGSN
as a whole. All of the new modes and commands within the SGSN-Global configuration mode will be identified and
defined in this section.

Important:
Remember, it is the
congestion-control
command in the Global Configuration mode that
enables / disables congestion control.
