Field Description

Service name

The name of the service configured in the named context.

Context

The name of the context where the service is configured.

State

The status of the service, i.e., "Initiated".

Echo Interval

The duration between the sending of GTP-U echo messages.

Sequence Number

Identifies if the sequence number is added to every GTP-U packet.

Include UDP Port Ext.Hdr

Indicates if an extension header, in the GTP-U packet header, allowing for error indication messages will be added.

Max-retransmissions

The number of user data packet request message retransmissions that can be sent before an error condition is established.

Retransmission Timeout

The number of seconds between the re-sending of GTP-U echo messages

IPSEC Tunnel Idle Timeout

The number of seconds an IPSec tunnel is idle before tunnel deletion is triggered.

Allow Error-Indication

Indicates if the error indication will be allowed or suppressed upon the receipt of a user data packet for a non-existent session.

Address List

Identifies the IP address used to transmit/receive GTP-U packets. Also indicates, if configured, the type of bearer traffic to be associated with the bind address (non-ims media only, ims-media only or all).

GTPU UDP Checksum

Indicates if the UDP checksum in UPD header of GTP-U packet is enabled/disabled and if it is optimized.

Possible values are:

  • Disabled

  • Enabled - Attempt Optimize Default Mode

  • Enabled - No Optimize

Path Failure Detection on gtp echo msgs

Identifies if the path failure detection is enabled upon reaching the maximum number of echo retransmissions.

Path Failure Clear Trap

Identifies the configuration of the path-failure clear-trap command.

Echo indicates that the path-failure trap will be cleared only on receipt of an echo message from the particular peer.

Non-echo indicates that the path-failure trap will be cleared on receipt of the first control plane message for that GTPU peer allocation.

GTPU Source-port Configuration

: Use Standard Port

GTPU Source-port Offset

The offset configured for the GTPU source port.

GTPU Peer Statistics Threshold

The maximum number of GTPU peers supported. The default value is 16000.

Note


In CUPS, the "Packets Discarded" statistics will be the aggregate of packets dropped at the Session manager and packets dropped at VPP. As VPP handles majority packets, the packet drops at VPP can only be categorized broadly under these statistics.

You can view specific packet drop reasons only for packets dropped at session manager. Packets dropped at VPP are categorized under Packets Discarded counter in the show gtpu statistics CLI.
