[local]hostname(config-sgsn-global)#
flush-frequency frequency
frequency : Enter an integer from 1 to 3. Default is 1.
num-msgs number_msgs
number_msgs : Enter the integer 1 (to disable aggregation) or an integer from 2 to 164 to define the number of messages. Default is 10.
To view aggregate IPC message statistics, use command show config | grep aggregate-ipc-msg.
Configure the linkmgr to buffer 45 messages before flushing the linkmgr IPC messages:
On HNB-GW the following command configures the linkmgr to flush the IPC messages towards CN without aggregation:
On HNB-GW the following command configures the sessmgr to flush the IPC messages towards CN without aggregation:
Important: This command is no longer available in all 12.0 and 12.2 releases. If you do not see this command in your release, look for the apn-resolve-dns-query snaptr command in the APN Profile configuration mode to accomplish the same task.Including default with the command configures the SGSN to use default behavior so that the SGSN sends BSSGP-Status messages whenever the SGSN receives an MS-Flow-Control message from an unknown MS.
To see the statistics for the number of MS-Flow-Control messages that have been discarded, use the show bssgp statistics command from the Exec mode.
Including default with the command configures the SGSN to use default behavior so that the SGSN continues with the current state once a peer-to-peer BVC Reset is received.
To confirm the configuration for the response to the BVC Reset, use the show sgsn-mode command from the Exec mode.
t2 T2_time
T2_time : Enter an integer from 1 to 120. Default is 30 seconds.
th TH_time
TH_time : Enter an integer from 6 to 5999. Default is 500 seconds.
Set the TH timeout for 20 seconds:
Include default with the command to disable the function.
Include no with the command to disable this function.
no dscp-template template_name
|
•
|
This command provides access to the mode containing all the configuration commands used to define DSCP markings for the control packets and data packets for a particular GPRS service (see the DSCP Template Configuration Mode Commands section).
|
|
•
|
To associated a specpific DSCP template with a specific GPRS service configuration, use the associate-dscp-template downlink documented in the GPRS Service Configuration Mode Commands section.
|
|
•
|
To check the list of DSCP templates configured, use the show sgsn-mode command documented in the Exec Mode Commands section.
|
Use a command similar to the following to create a DSCP template with ID dscp_london that can be used specifically for Gb/IP calls from subscribers in London:
Important: For the dual PDP addressing feature to function, common-flags must be enabled with the gptc send command in the SGTP service configuration mode prior to enabling the feature with the dual-address-pdp command.|
•
|
dual-address-pdp command in the RNC configuration mode disables SGSN support for dual PDP type addressing for a specific RNC that either does or does not support this type of addressing..
|
|
•
|
pdp-type-ipv4v6-override in the APN profile configuration mode allows the SGSN to override the MS/UE request for dual PDP type addressing.
|
|
•
|
Using the dual-ipv4v6 keyword with the wildcard-apn pdp-type command in the APN remap table configuration mode enables the operator to configure a default APN with a wildcard subscription with PDP type IPv4v6.
|
If dual PDP addressing has been disabled, to renable the feature, move to the SGTP service configuration mode, in the appropriate context, to perform the following as the first command needed to re-enable support for dual PDP type addressing in the configuration:
|
•
|
The old-tlli invalidate tlli command configures a list of random TLLI to be invalidated from the GMM after the invalidate old-TLLI timer expires.
|
|
•
|
The old-tlli hold-time command configures the old-TLLI expiry timer.
|
imsi-range mcc mcc_num mnc mnc_num { msin first start_number last stop_number [ operator-policy policy_name [ description description ] ] | plmnid plmn_id operator-policy policy_name [ description description ] } +
Using no in the command deletes the definition from the SGSN Global configuration.
mcc mcc_num
mcc defines the mobile country code (MCC) of an IMSI.
mcc_num: Enter a 3-digit number from 100 to 999 - 000 to 099 are reserved.
mnc mnc_num
mnc defines the mobile network code (MNC) of an IMSI.
mnc_num: Enter a 2 or 3-digit number from 00 to 999.
first start_num: Defines first MSIN prefix number in a range
last stop_num: Defines the last or final MSIN prefix number in a range.
policy_name : Enter a string of 1 to 64 alphanumeric characters.
description: Enter a string of 1 to 100 alphanumeric characters to provide range clarification for converted Release 9.0 configurations.
If a PLMN-ID is to be included in the definition, enter the plmnid before entering the operator policy name.
plmnid plmn_id
plmn_id : Enter 5 to 6 digits.
The following associates operator policy oppol1 with country code 310, mobile network code of 33, and IMSI range 1231234 - 1231244:
max-pending-attaches limit
limit : Enter an integer from 5000 - 50000. Default is 10000.
As the IMSIMgr gets busier and does not responded to Query/Forward requests, the response to the requests will get slower and slower and the queue size continues inflating if the incoming message rate is high. To avoid this situation, set the max-pending-attaches for the pending queue for Attach and RAU messages. All other messages from the HLR will be added to the queue as they cannot be dropped. High and low watermarks are set to the queue at 80% of max-pending-attaches ” and 60% of max-pending-attaches respectively.
Set the queue length to a maximum of 15000 requests:
[ no ] old-tlli invalidate tlli < hexadecimal >
Important: If the old-TLLI expiry timer is not configured with the old-tlli hold-time command, then the SGSN will only drop second Attach Requests using the same random TLLI already in use.|
•
|
The gmm-message configures the SGSN to discard (drop) the Attach-Request message received with a random TLLI already in use
|
|
•
|
The old-tlli hold-time command configures the old-TLLI expiry timer.
|
Add random TLLI 0x7f05a30a to the Invalidate List:
[ default ] old-tlli hold-time < seconds >
Important: For this configuration to work, the list of random TLLI to be removed (invalidated) from the GMM must be defined with the old-tlli invalidate tlli command.|
•
|
The gmm-message configures the SGSN to discard (drop) the Attach-Request message received with a random TLLI already in use
|
|
•
|
The old-tlli invalidate tlli command configures the random invalidate TLLI list.
|
Set the timer for 2 seconds:
connected-ready rate
rate -sets the number of subscribers to be deactivated per second per SessMgr and the valid range is 1 to 1000 and the default is 760 connected-ready subscribers deactivated per second.
idle-standby rate
rate - sets the number of subscribers to be deactivated per second per SessMgr and the valid range is 1 to 1000 and the default is 240 idle-standby subscribers deactivated per second.
|
•
|
max-remote-restart-counter-change - allows the operator to set a maximum variance between stored and received values for restart counter changes coming from the GGSN. For details, refer to the SGSN Global configuration mode documentation.
|
|
•
|
disable-remote-restart-counter-verification - allows the operator to disable the default behavior. For details, refer to this command in the SGSN Global configuration mode documentation.

Use the following command to deactivate PDP connections for 600 PMM-Connected / GPRS-Ready subscribers per second:
Use the following command to deactivate PDP connections for 320 PMM-Idle / GPRS-Standby subscribers per second:
Use the following command to reset the default 760 per second deactivation rate for PMM-Connected / GPRS-Ready subscribers:
Confirm RIM configuration with the show sgsn-mode command in the Exec mode.
Important: The value for this command can not be altered once dynamic offloading has begun - refer to the command description for the sgsn-offload command in the Exec Mode chapter..Include default with the command to disable the audit function.
Include no with the command to disable the audit function.
Including no with the command disables the authentication.
