Cisco Cisco Packet Data Gateway (PDG)
With Release 17.0 and higher, to define a policy you must first select one of the three congestion levels:
critical, major or minor. Next select the service with the sgsn-service keyword and then associate a
congestion-action-profile. Refer to the congestion-action-profile command in the SGSN-Global Configuration
mode to create the congestion-action-profiles which define the congestion response actions to be taken when
thresholds are exceeded for the SGSN.

sgw-service
Specifies the Congestion Control policy action for the S-GW service.
Supported policy actions are:
• drop: Specifies that the system should drop incoming packets containing new session requests.
• none: Specifies that the system should take no action.
• reject: Specifies that the system processes new session request messages and responds with a reject
message.
For S-GW sessions/calls, redirect action is not supported.
wsg-service
Specifies the Congestion Control policy action for the WSG service.
Supported policy actions are:
• drop: Specifies that the system should drop incoming packets containing new session requests.
• none: Specifies that the system should take no action.
• reject: Specifies that the system processes new session request messages and responds with a reject
message.
action { drop | none | redirect | reject }
Specifies the policy action:
• drop: Specifies that the system should drop incoming packets containing new session requests.
• none: Specifies that the system should take no action. This is the default for PDIF-service.
• redirect: Specifies that the system should redirect new session requests to an alternate device. (HA,
HSGW, and PDSN only)
If this option is used, the IP address of the alternate device must be configured using
the policy overload redirect command that is part of the service configuration. Note
that this option can not be used in conjunction with GGSN, MME, P-GW, SAEGW, or
S-GW services.
