Configuring Congestion Control - Cisco ASR 5000 Administration Manual

RADIUS-based Enhanced Wireless Access Gateway Configuration
Notes:
 For detailed information on R-eWAG-related bulk statistics available in the IPSG schema, refer to the IPSG
Schema chapter of the Statistics and Counters Reference, and for those available in the System schema, refer to
the System Schema chapter of the Statistics and Counters Reference.
 Apart from the IPSG and System schema, as needed you can also configure variables available in the other
schema, including:
 APN: For Access Point Name (APN) related statistics
 Card: For card-level statistics
 Context: For context service related statistics
 ECS: For Enhanced Charging Service related statistics
 Port: For port-level statistics
 RADIUS: For per-RADIUS server statistics
 The following is a sample schema format for R-eWAG statistics:
"eWAG Schema: Test\n ----------------------\nVPN Name:%vpnname%,\nService
Name:%servname%,\n Session Statistics: \n Total Current Sessions
:%total_current_sessions%,\n Total Sessions Setup: %total_sessions_setup%,\n -----
-----------------\n"

Configuring Congestion Control

To enable Congestion Control, use the following configuration:
configure
#To enable Congestion Control:
congestion-control
#To configure Congestion Control policy:
congestion-control policy ipsg-service action { drop | none }
#To configure Congestion Control thresholds:
congestion-control threshold { { license-utilization | max-sessions-per-service-
utilization | message-queue-utilization | port-rx-utilization | port-specific {
<slot/port> | all { rx-utilization | tx-utilization } } | port-specific-rx-utilization |
port-specific-tx-utilization | port-tx-utilization | service-control-cpu-utilization |
system-cpu-utilization | system-memory-utilization | tolerance } [ critical ]
<percentage> | message-queue-wait-time [ critical ] <seconds> | { port-specific-rx-
utilization | port-specific-tx-utilization } [ critical ] }
end
Notes:
 Congestion policies are configurable for each service. These policies dictate how the services respond when the
system detects that a congestion condition threshold has been crossed. For more information on the Congestion
Control feature, refer to the Congestion Control chapter of the System Administration Guide.
