S-GW Service Configuration Mode Commands


S-GW Service Configuration Mode Commands
 
 
The S-GW (Serving Gateway) Service Configuration Mode is used to create and manage the relationship between an eGTP service used for either ingress or egress control plane and user data plane network traffic.
 
 
accounting context
Configures the GTPP accounting context and group selection for S-GW service.
Product
S-GW
Privilege
Administrator
Syntax
accounting context name [ gtpp group name ]
no accounting context
no
Removes the configured accounting context from this service.
context name
Specifies the context where GTPP accounting is performed. name must be an existing context configured on the system and be from 1 to 79 alpha and/or numeric characters.
If an accounting context name is not configured in the S-GW service, the context where the S-GW service resides is considered the accounting context and the default GTPP group is used.
gtpp group name
Specifies a GTPP group used to perform GTPP accounting. name must be an existing GTPP group configured on the system and be from 1 to 79 alpha and/or numeric characters.
If a GTPP group is not configured, the system will use the default GTPP group in the specified accounting context. If the accounting context is not specified, the system will use default GTPP group in the context where the S-GW service resides.
Usage
Use this command to specify the accounting context and/or GTPP accounting group the S-GW service will use to perform GTPP accounting.
Example
The following command specifies a GTPP accounting context named acct-2 and a GTPP accounting group named gtpp-grp-3 as the context and group the S-GW service will use:
accounting context acct-2 gtpp group gtpp-grp-3
 
associate

qci-qos-mapping name
Associates the S-GW service with QCI to QoS mapping parameters. name must be an existing QCI-QoS mapping configuration and be from 1 to 63 alpha and/or numeric characters.
QCI-QoS mapping is configured through the qci-qos-mapping command in the Global Configuration Mode.
Usage
Use this command to select a pre-configured QoS mapping and/or policy control and charging configuration to be used by the S-GW service.
Example
The following command associates the S-GW service with an IMS authorization service named ims-23:
associate ims-auth-service ims-23
 
egtp-service

Usage
Use this command to configure the eGTP service to use with this S-GW service. The eGTP service must be existing and be configured with the appropriate parameters supporting the intended service type.
Example
The following command configures the S-GW service to use an eGTP service named s1u-egtp as it’s ingress service:
egtp-service ingress service s1u-egtp

gtpu-error-ind
Configures the actions to be taken upon receiving a GTP-U error indication from an eNodeB or P-GW.
Product
S-GW
Privilege
Administrator
Syntax
gtpu-error-ind { s1u { local-purge | page-ue [ custom1-behavior ] } | s5u { local-purge | signal-peer } }
default gtpu-error-ind { s1u | s5u }
default
Rests the command to the default action for the specified interface. For S1-U, page-ue is the default action. For S5-U, local-purge is the default action.
s1u { local-purge | page-ue [ custom1-behavior ] }
Specifies the action to take when a GTP-U error indication is received from an eNodeB over the S1-U interface.
local-purge: The S-GW clears the affected bearer (or PDN if error-ind is received on default bearer) locally without informing peer.
page-ue [ custom1-behavior ]: The S-GW moves the complete UE state to S1-Idle and starts paging for this UE. If the custom1-behavior option is specified, the S-GW will guard the paging attempt with a timer of 60 seconds. Within this time the bearer must have the eNodeB TEID refreshed by an MME. Otherwise, the S-GW will clear the affected bearer with signaling. This is the default action for GTP-U error indication messages received on the S1-U interface.
s5u { local-purge | signal-peer }
Specifies the action to take when a GTP-U error indication is received from a P-GW over the S5-U interface.
local-purge: The S-GW clears the affected bearer (or PDN if error-ind is received on a default bearer) locally without informing the peer. This is the default action for GTP-U error indication messages received on the S5-U interface.
signal-peer: The S-GW initiates control signalling towards the peer MME and P-GW. When signalling:
Usage
Use this command to specify the action to taken upon receiving a GTP-U error indication from either an eNodeB across an S1-U interface or from a P-GW across an S5-U interface.
Example
The following command sets the action to take upon receipt of a GTP-U error indication from the eNodeB to clear affected bearer:
gtpu-error-ind s1u local-purge
 
mag-service
Identifies the Mobile Access Gateway (MAG) egress service through which calls are to be routed for this S-GW service.
Product
S-GW
Privilege
Administrator
Syntax
mag-service egress service name
no mag-service egress service
no
Removes the configured MAG egress service from this service.
egress service name
Specifies the MAG service name to be used as the egress MAG service on a PMIP based S5/S8 interface. name must be an existing MAG service and be from 1 to 63 alpha and/or numeric characters.
Usage
Use this command to specify the name of the MAG service where calls are to be routed.
Example
The following command specifies that an existing MAG service named mag3 is to be used to route call through for this S-GW service:
mag-service egress service mag3
 
path-failure
Configures the action to take upon the occurrence of a path failure between the S-GW and the MME, P-GW, or eNodeB.
Product
S-GW
Privilege
Administrator
Syntax
path-failure { s11 | s1u | s5 | s5u } ( local-purge | signal-peer }
default path-failure { s11 | s1u | s5 | s5u }
default
Returns the command to the default setting of “local purge” for the selected interface.
{ s11 | s1u | s5 | s5u }
Specifies the interface to which the action will be applied.
s11: Indicates that the path failure action is to be applied to the S11 interface between the S-GW and the MME.
s1u: Indicates that the path failure action is to be applied to the S1-U interface between the S-GW and the eNodeB.
s5: Indicates that the path failure action is to be applied to the S5 interface between the S-GW and the P-GW.
s5u: Indicates that the path failure action is to be applied to the S5-U interface between the S-GW and the P-GW.
( local-purge | signal-peer }
Specifies the action to apply to the selected interface.
local-purge: The S-GW clears the affected bearer (or PDN if path failure is received on a default bearer) locally without informing the peer. This is the default action for all interface.
signal-peer: The S-GW initiates control signalling towards the peer MME and P-GW. When signalling:
Usage
Use this command to specify the type of action to take when a path failure occurs on one of the supported interfaces.
Example
The following command sets the path failure action for the S5 interface to “signal peer”:
path-failure s5 signal-peer
