About this Guide


Note


Control and User Plane Separation (CUPS) represents a significant architectural change in the way StarOS-based products are deployed in the 3G, 4G, and 5G networks. Unless otherwise specified, it should not be assumed that any constructs (including, but not limited to, commands, statistics, attributes, MIB objects, alarms, logs, services) referenced in this document imply functional parity with CUPS products. References to any CUPS products or features are for informational purposes only. Please contact your Cisco Account or Support representative for any questions about parity between this product and any CUPS products.

Note


The documentation set for this product strives to use bias-free language. For purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Note


The HA, HSGW, PDSN, and SecGW products have reached end of life and are not supported in this release. Any references to these products (specific or implied) their components or functions including CLI commands and parameters in this document are coincidental and are not supported. Full details on the end of life for these products are available at https://www.cisco.com/c/en/us/products/collateral/wireless/asr-5000-series/eos-eol-notice-c51-740422.html.


This preface describes the S-GW Administration Guide, how it is organized and its document conventions.

The Serving Gateway (S-GW) routes and forwards data packets from the UE and acts as the mobility anchor during inter-eNodeB handovers. Signals controlling the data traffic are received on the S-GW from the MME which determines the S-GW that will best serve the UE for the session. Every UE accessing the EPC is associated with a single S-GW. This document provides feature descriptions, configuration procedures and monitoring and troubleshooting information.

Conventions Used

The following tables describe the conventions used throughout this documentation.

Notice Type Description

Information Note

Provides information about important features or instructions.

Caution

This document always gives the full form of a command in lowercase letters. Commands are not case sensitive.

This typeface represents a variable that is part of a command, for example:

show card slot_number

slot_number is a variable representing the desired chassis slot number.

Command Syntax Conventions

Description

{ keyword or variable }

Required keyword options and variables are those components that are required to be entered as part of the command syntax.

Required keyword options and variables are surrounded by grouped braces { }. For example:

sctp-max-data-chunks { limit max_chunks | mtu-limit } 

If a keyword or variable is not enclosed in braces or brackets, it is mandatory. For example:

snmp trap link-status 
[ keyword or variable ]

Optional keywords or variables, or those that a user may or may not choose to use, are surrounded by brackets.

|

Some commands support multiple options. These are documented within braces or brackets by separating each option with a vertical bar.

These options can be used in conjunction with required or optional keywords or variables. For example:

action activate-flow-detection { intitiation | termination }  
or
ip address [ count number_of_packets | size number_of_bytes ]
