> GTP-U Service Configuration Mode Commands
> The GTP-U Service Configuration Mode is used to manage parameters applied to incoming GTP-U packets.
> bind
> Configures the IP address to use for GTP-U data packets.
> Product
> GGSN, P-GW, S-GW
> Privilege
> Administrator
> Syntax
> [ no ] bind { ipv4-address ipv4_address [ ipv6-address ipv6_address ] | ipv6-address ipv6_address [ ipv4-address ipv4_address ] }
> no
> removes a configured IP address from this service.
> 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.
> Usage
> Use this command to bind the service to an interface for sending/receiving GTP-U packets.
> Example
> The following command configures the IPv4 address for this GTP-U service as 1.2.3.4:
> bind ipv4-address 1.2.3.4
> echo-interval
> Configures the rate at which GPRS Tunneling Protocol (GTP) v1-U echo packets are sent.
> Product
> GGSN, P-GW, S-GW
> Privilege
> Administrator
> Syntax
> echo-interval seconds
> [ default | no ] echo-interval
> default
> Returns the command to its default setting of disabled.
> no
> Removes the configured echo-interval setting.
> seconds
> Specifies the number of seconds between the sending of a GTP-Uv1 echo packet. seconds must be an integer value from 60 to 3600.
> Usage
> Use this command to configure the rate at which GTP-Uv1 echo packets are sent.
> Example
> The following command sets the rate between the sending of echo packets at 120 seconds:
> echo-interval 120
> end
> Exits the current mode and returns to the Exec Mode.
> Product
> All
> Privilege
> Administrator
> Syntax
> end
> Usage
> Change the mode back to the Exec mode.
> exit
> Exits the current mode and returns to the previous mode.
> Product
> All
> Privilege
> Administrator
> Syntax
> exit
> Usage
> Return to the previous mode.
> extention-header
> Configures the addition of an extention header ,in the GTP-U packet header, allowing for error indication messages.
> Product
> GGSN, P-GW, S-GW
> Privilege
> Administrator
> Syntax
> [ default | no ] extention-header source-udp-port
> default
> Returns the command to its default setting of disabled.
> no
> Disables the feature.
> source-udp-port
> Configures extension header type UDP Port support in GTP-U header for GTP-U Error Indication messages.
> Usage
> Example
> The following command enables the inclusion of an extention header to allow for error indication messages:
> extention-header source-udp-port
> max-retransmissions
> Configures the maximum retry limit for GTP-U echo retransmissions.
> Product
> GGSN, P-GW, S-GW
> Privilege
> Administrator
> Syntax
> max-retransmissions num
> no max-retransmissions
> no
> Disables the feature.
> num
> Default: 4
> Specifies the number of GTP-U echo message retransmissions allowed before triggering a path failure error condition. num must be an integer value from 0 to 15.
> Usage
> Use this command to set the maximum number of GTP-U echo message retransmissions in order to define a limit that triggers a path failure error.
> Example
> The following command sets the maximum GTP-U echo message retransmissions for this service to 10:
> max-retransmissions 10
> path-failure detection-policy
> Configures a path failure detection policy on GTP-U echo messages that have been retransmitted the maximum number of retry times.
> Product
> GGSN, P-GW, S-GW
> Privilege
> Administrator
> Syntax
> path-failure detection-policy gtp echo
> [ default | no ] path-failure detection-policy
> default
> Resets the command to its default setting of enabled.
> no
> Disables the feature.
> gtp echo
> Sets the detection policy to detect a failure upon reaching the maximum number of GTP-U echo message retransmissions.
> Usage
> Use this command to set the detection policy for path failures.
> Example
> The following command sets the path failure detection policy to detect failures upon reaching the maximum number of GTP-U echo message retries:
> path-failure detection-policy gtp echo
> retransmission-timeout
> Configures retransmission timeout for GTPU echo message retransmissions for this service.
> Product
> GGSN, P-GW, S-GW
> Privilege
> Administrator
> Syntax
> retransmission-timeout seconds
> default retransmission-timeout
> default
> Returns the command to its default setting of 5.
> seconds
> Default: 5
> Specifies the number of seconds between the re-sending of GTP-U echo messages. seconds must be an integer value between 1 and 20.
> Usage
> Use this command to set the number of seconds between the retransmission of GTP-U echo messages.
> Example
> The following command sets the number of seconds between the sending of GTP-U echo messages to 7:
> retransmission-timeout 7
