The Tethering Detection Bypass mechanism is enhanced to support multiple interfaces.

21.24.2

Feature Description

In P-GW, the Tethering Detection feature supports up to 10 interface IDs through the CLI and allows bypassing subscribers from tethering rules. If the tethered data flow comes with the configured IPv6 interface IDs, P-GW bypasses that data from tethering. P-GW also allows deletion of all or multiple interface IDs from the tethering detection bypass list.

Configuring tethering-detection bypass interface-id

Use the following configuration to add, remove, or delete multiple interface IDs.

configure 
   active-charging-service service_name 
      [ no ] tethering-detection {  bypass interface-id ipv6 ifid | tac-db bypass interface-id ipv6 ifid  } 
      default tethering-detection 
      exit 
   exit

NOTES:

  • tethering-detection { bypass interface-id ipv6 ifid } : Configures multiple interface IDs. You can configure a maximum of 10 interface IDs.

    Example for Multiple interface Ids: tethering-detection bypass interface-id 00-00-00-05-47-00-37-44 00-00-00-05-47-00-37-45 00-00-00-05-47-00-37-46 00-00-00-05-47-00-37-4700-00-00-05-47-00-37-48 00-00-00-05-47-00-37-49 00-00-00-05-47-00-37-50 00-00-00-05-47-00-37-51 00-00-00-05-47-00-37-52 00-00-00-05-47-00-37-53

  • default tethering-detection : Removes all the configured interfaces.

  • no tethering-detection bypass interface-id if-id1 if-idn : Removes the specified if-id1 and if-idn interfaces if configured.

    If no interface IDs are present, then all the configured intreface IDs are removed.

  • tac-db bypass interface-id ipv6 ifid : Enables TAC-db lookup for specified interface IDs.

Verifying the Configuration

Use the following commands to verify the tethering-detection bypass interface ID configuration.

  • show configuration

  • show configuration verbose

Use the following sample commands to verify the configuration. 

configure 
   active-charging-service service_name 
      tethering-detection { bypass interface-id  ipv6 ifid  } 
      exit 
   exit

Monitoring and Troubleshooting

This section provides information regarding show commands available for the Tethering Detection feature.

Show Command and Output

This section describes the show command and output to view the current configuration for tethering-detectiion attribute.

show active-charging-tethering-detection statistics

The output of this command includes the following field:

  • Total flows bypassed for scanning: If a flow gets by-passed on a configured interface Id, the Total flows bypassed for scanning counter is incremented.
