eGTP Service Configuration Mode Commands
 
 
The eGTP Service Configuration Mode is used to create and manage eGTP interface types and associated parameters.

Syntax
gtpc { bind { ipv4-address ipv4_address [ ipv6-address ipv6_address ] | ipv6-address ipv6_address [ ipv4-address ipv4_address ] } | echo-interval seconds | ip qos-dscp { forwarding_type } | max-retransmissions num | retransmission-timeout seconds }
no gtpc { bind { ipv4-address ipv4_address [ ipv6-address ipv6_address ] | ipv6-address ipv6_address [ ipv4-address ipv4_address ] } | echo-interval }
default gtpc { echo-interval | ip qos-dscp | max-retransmissions | retransmission-timeout }
no
Disables or removes the configured GTP-C setting.
default
Resets the specified parameter to its default value.
bind { ipv4-address ipv4_address [ ipv6-address ipv6_address ] | ipv6-address ipv6_address [ ipv4-address iv4p_address ] }
Binds the service to an interface with an IPv4 address, IPv6 address or both.
ipv4-address ipv4_address [ ipv6-address ipv6_address ]: Binds this service to the IPv4 address of a configured interface. Optionally, bind the service to a configured interface with an IPv6 address. ipv4_address must be entered as a standard IPv4 address in dotted decimal notation. ipv6_address must be entered as a standard IPv6 address in colon-separated notation.
ipv6-address ipv6_address [ ipv4-address ipv4_address ]: Binds this service to the IPv6 address of a configured interface. Optionally, bind the service to a configured interface with an IPv4 address. ip6_address must be entered as a standard IPv6 address in colon-separated notation. ipv4_address must be entered as a standard IPv4 address in dotted decimal notation.
echo-interval seconds
Default: 60
Configures the duration between the sending of echo messages. seconds must be an integer value from 60 to 3600.
ip qos-dscp { forwarding_type }
Default: af11
Specifies the IP QoS DSCP per-hop behavior to be marked on the outer header of signalling packets originating from the LTE component. This is a standards-based feature (RFC 2597). The following forwarding types are supported:
af11: Designates the use of Assured Forwarding 11 per-hop behavior
af12: Designates the use of Assured Forwarding 12 per-hop behavior
af13: Designates the use of Assured Forwarding 13 per-hop behavior
af21: Designates the use of Assured Forwarding 21 per-hop behavior
af22: Designates the use of Assured Forwarding 22 per-hop behavior
af23: Designates the use of Assured Forwarding 23 per-hop behavior
af31: Designates the use of Assured Forwarding 31 per-hop behavior
af32: Designates the use of Assured Forwarding 32 per-hop behavior
af33: Designates the use of Assured Forwarding 33 per-hop behavior
af41: Designates the use of Assured Forwarding 41 per-hop behavior
af42: Designates the use of Assured Forwarding 42 per-hop behavior
af43: Designates the use of Assured Forwarding 43 per-hop behavior
be: Designates the use of Best Effort forwarding per-hop behavior
ef: Designates the use of Expedited Forwarding per-hop behavior typically dedicated to low-loss, low-latency traffic.
The assured forwarding behavior groups are listed in the table below.
Traffic marked with a higher class is given priority during congestion periods. If congestion occurs to traffic with the same class, the packets with the higher AF value are dropped first.
max-retransmissions num
Default: 4
Configures the maximum number of retries for packets. num must be an integer from 0 through 15.
retransmission-timeout seconds
Default: 5
Configures the control packet (echo message) retransmission timeout in GTP, in seconds. seconds must be an integer value from 1 through 20.
Usage
Use this command to configure GTP-C settings for the current service. This interface assumes the characteristics of an S11 reference point on the S-GW or MME.
Example
The following command binds the service to a GTP-C interface with an IP address of 112.334.556.778:
gtpc bind address 112.334.556.778
 
interface-type
Configures the interface type used by this service.
Product
MME, P-GW, S-GW
Privilege
Administrator
Syntax
interface-type { interface-mme | interface-pgw-ingress | interface-sgsn | interface-sgw-egress | interface-sgw-ingress }
{ interface-mme | interface-pgw-ingress | interface-sgsn | interface-sgw-egress | interface-sgw-ingress }
interface-mme: Specifies that the interface has the characteristics of an eGTP MME S11 reference point to/from an S-GW.
interface-pgw-ingress: Specifies that the interface has the characteristics of an eGTP P-GW S5/S8 reference point from an S-GW. The interface assumes the characteristics of either a GTP-C (control Plane) or GTP-U (user plane) reference point.
interface-sgsn: Specifies that the interface has the characteristics of an eGTP S-GW S4 reference point to/from an SGSN.
interface-sgw-egress: Specifies that the interface has the characteristics of an eGTP S-GW S5/S8 reference point to an eGTP P-GW. The interface assumes the characteristics of either a GTP-C (control Plane) or GTP-U (user plane) reference point.
interface-sgw-ingress: Specifies that the interface has the characteristics of:
Usage
Use this command to specify the type of interface this service uses. By configuring this command, the interface takes on the characteristics of the selected type.
Example
The following command configures the interface bound to this service to maintain the characteristics of an eGTP-C S-GW S11 reference point from an MME:
interface-type interface-sgw-ingress
 
validation-mode
Configures the type of validation to be performed on messages received by this service.
Product
P-GW
Privilege
Administrator
Syntax
validation-mode { custom1 | standard }
default validation-mode
default
Returns the command to the default setting of standard.
{ custom1 | standard }
custom1: Specifies that the message should be validated based on a vendor-specific set of mandatort elements.
standard: Specifies that the message should be validated based on the set of mandatort elements as defined in 3GPP 29.274.
Usage
Use this command to specify the type of validation performed on messages received by this service. The information elements contained in messages have mandatory elements and conditional elements. The standard set of elements, as defined by 3GPP 29.274 is checked if this command is set to “standard”. The custom1 setting is for a vendor-specific set of mandatory elements.
Example
The flowering command sets the validation mode for incoming messages to standard:
validation-mode standard
