Output Fields

Table 1 lists the Access and Mobility Management Function (AMF) output fields for the show services agf ngap command.

Table 1: show services agf ngap (AMF outputs)

Field Name

Field Description

AMF

AMF name in the configuration.

Backup AMF name

Fully qualified domain name (FQDN) of the backup AMF for the Globally Unique AMF ID (GUAMI). The AMF provides the GUAMI during the NG Setup Procedure. If the AMF does not provide a backup AMF name, then Junos OS displays None is displayed.

Default

Identifies whether the AMF is configured as a default AMF.

  • Yes—This is configured as the default AMF.

  • No—This is not a default AMF.

IP address

IP address configured for the AMF.

MCC

Mobile Country Code

MNC

Mobile Network Code

Name

Globally unique FQDN provided by the AMF during the NG Setup Procedure. This name must be published in the Domain Name System (DNS).

Node id

Uniquely configured AMF node ID used internally by the AGF to identify the AMF.

Overload State

Current AMF overload state. When the AMF is in the overload state, the AGF does not select the AMF for any new user equipment (UE) setups

Port

If you do not configure the number, Junos OS uses the default port 38412.

Routing Instance

Configured AMF routing instance. The IP address for the AMF must be reachable in the configured routing instance.

SD

Slice Differentiator

Served GUAMI

List of Global Unique AMF Identifier (GUAMIs). The GUAMI consists of:

  • PLMN ID—Public land mobile network identifier which consists of an MCC and MNC.

  • Region ID—AMF region identifier.

  • AMF Set ID—AMF set identifier. The AMF set ID identifies the AMF set within the AMF region.

  • Pointer—AMF pointer. The AMF pointer identifies one or more AMFs within the AMF set.

SST

Service Slice Type

  • Embb—Enhanced mobile broadband

  • Miot— Massive IoT

  • Urllc—Ultra-reliable, low latency communications

  • V2x—Vehicle-to-everything

State

The AMF can have one of the following states:

  • Offline—The AGF is not connected to the AMF.

  • Offline (Admin) —The AGF is administratively disabled. The AMF configuration was not found.

  • Connecting—The AGF is in the process of connecting to the AMF.

  • Initializing—The AGF is in the initial state of NG Setup.

  • Online—The AGF has completed the NG setup and is ready to service UE contexts.

Tracking areas

Configured AMF tracking areas.

UE count

Current number of UEbeing serviced by the AMF.

Table 3 lists the TNLA output fields for the show services agf ngap command.

Table 2: show services agf ngap (TNLA outputs)

Field Name

Field Description

TNLA

Transport Layer Network Association Identifier

Type

Type of TNLA association .

  • Static—Initial TNLA established. Static TNLA is based on the AGF configuration.

  • Dynamic—Subsequent TNLA added by the AMF as a result of N2 AMF signal update messages.

Usage Type

Identifies the type of NGAP packets that are permitted on the TNLA.

  • UE associated signalling

  • Non-UE associated signalling

  • Non-UE associated signalling

Weight Factor

The AMF sets theTNLA weight factor. The AGF uses the weight factor to load balance NGAP UE-associated messages across all TNLAs. The Range of values is 0 through 255. When the AGF receives a weight factor of zero, AGF prevents the allocation of TNLA from future UE registrations.

State

Current TNLA status:

  • Establishing—Indicates the association is in the process of being established.

  • Established—TNLA has been established and can exchange NGAP packets with the AMF.

Bound UE Count

Current number of UEs bound to the TNLA

Packets Sent

Number of NGAP packet sent on the TNLA.

Packets Received

Number of NGAP packet received on the TNLA.

Local IP Address

The IP address of the local endpoint.

Port

The port number of the local endpoint.

Peer IP Address

 IP address of the peer SCTP endpoint.

Port

Port number of the peer SCTP endpoint.
State

Current status of the peer IP address.

  • Inactive—IP address cannot be reached.

  • Active—IP address is active and reachable.

  • Unconfirmed—The heartbeat connection has not been established between AGF and AMF. Data has not been received from this IP address.

Table 3 lists the UE output fields for the show services agf ngap command.

Table 3: show services agf ngap Output Fields (UE outputs)

Field Name

Field Description

AMF TNLA

 AMF TNLA that the UE is currently bound to. A value of -1 indicates that the UE is currently not bound to any TNLA..

AMF GUAMI

Globally Unique AMF Identifier assigned to service the UE context.

AMF UE ID

 UE identifier allocated by the AMF.

AMF GUAMI

Globally Unique AMF Identifier assigned to service the UE context.

RM State

Current registration management state. Registration management state is defined by the Third-Generation Partnership Project (3GPP).

  • RM_REGISTERED—The UE is registered with the 5GC.

  • RM_DEREGISTERED—The UE is not registered with the 5GC.

State

Current internal Next Generation Application Protocol (NGAP) UE state.

  • Establishing—The UE context is being set up in the AMF.

  • Established—The UE context setup is complete.

  • Releasing —The UE has requested the AMF to release the UE logical NG connection.

  • Released —The UE context has been released.

Type

UE Type.

  • Fixed Network Residential Gateway (FN-RG)

  • 5G Residential Gateway (5G-RG)

UE identifier

User equipment identifier. The identifier uniquely identifies the UE within the AGF.
