Description

Supporting IPv6 Only eNB Insertion through Show and Clear Subscriber CLI commands

 2024.02.0

Before you add IPv6 only eNBs in a network, all UPFs in a mesh must be IPv6 enabled for successful handovers of IPv4 only eNB sessions to IPv6 only eNB sessions. In addition, all sessions must have V4V6 tunnel before inserting a V6 only eNB. To support this IPV6 only eNB insertion, cnSGW-c includes the following CLI commands:

  • The show subscriber nf-service sgw data-tunnel data_tunnel_type and show subscriber count nf-service sgw data-tunnel data_tunnel_type CLI commands

  • The clear subscriber nf-service sgw data-tunnel data_tunnel_type CLI command

Default Setting: Not Applicable

This section describes troubleshooting information.

  • To display the SGW subscriber information, use the following commands:

    show subscriber namespace sgw imsi imsi_value

    show subscriber nf-service sgw imsi imsi_value

    show subscriber count { all } 

    show subscriber namespace sgw imsi 123456789012348

Logs

The system logging feature provides a common way to log the log messages across applications. Each log consists of the following components:

  • Timestamp—Shows the date and time of the log creation.

  • Log message—Shows the message of a specific log.

  • Log level—Shows the level of importance of log message.

  • Log tag—Shows the details of module name, component name, and interface name. A log tag is pre-created and passes during logging.
