Configuring MAG-c

The quick-start instructions provide the basic steps required to configure the MAG-c for subscriber management, with references to additional topics for users who want more information.

Identify the name of the IES or VPRN service used to host subscriber sessions on the BNG-UP; see Service selection.
Ensure the BNG-UP is configured; see the 7750 SR and VSR BNG CUPS User Plane Function Guide, "PFCP association" and "Session management", for more information.

This task provides basic steps that describe the minimal configuration required to allow subscriber-session creation on the MAG-c. The steps provide references to more detailed information about each topic.

Configure the system resources as shown in the following example.
The values specified in the example are for a MAG-c with a single VM instance. The assumption is the resource pool, gateway, card, and group are already configured. See CP session state and VM resilience for information about different VM resiliency models.

            group 1 resource-pool 1
                no shutdown
            exit
----------------------------------------------
```
Configure IP connectivity between the MAG-c and BNG-UP.
The following example shows a MAG-c directly connected to a BNG-UP. Connectivity to the system interface is also required for basic MAG-c functionality. See the7450 ESS, 7750 SR, 7950 XRS, and VSR Interface Configuration Guide for information about IP routing configuration.
IP connectivity between the MAG-c and BNG-UP
```
A:mag-c>config>router# info

        port 1/2/1
        no shutdown
    exit
----------------------------------------------
```

Create a PDN instance and under it configure the PFCP association between the MAG-c and the BNG-UP.

The following example shows a minimal configuration required to form a PFCP association between the MAG-c and the BNG-UP. See PFCP association and path for more information.

Configure the following, depending on whether you are configuring a fixed-access or FWA session:
- For fixed-access sessions, configure IBCP to allow tunneling of IPoE sessions.
  The default IBCP tunnel supports tunneling of control packets from the BNG-UP to the MAG-c. The following example configures IPoE-based tunneling sessions. See In-band control plane and BNG-UP selection for more information about IBCP.
IPoE-based tunneling configuration for the IBCP tunnel
```

            exit

                exit
            exit
----------------------------------------------
```
- For 4G FWA sessions, configure the S11 and S5 endpoints to enable control plane communication toward the MME.
  The following example shows a 4G FWA configuration for control plane traffic toward the MME. You require the S5 interface, even though it is internal.
  
  Note: 5G FWA sessions follow similar steps that are not described in this quick-start procedure. See 4G and 5G NSA option 3 sessions and 5G standalone sessions for more information about configuring 4G and 5G sessions.

Configure a local address pool for IP address assignment.

The following example shows a simple address pool configuration that uses the prefix 192.168.2.0/24 for an IP address assignment. Other methods can also be used. See Local address assignment for more information about IP address assignment.

Local address pool configuration for IP address assignment

A:MAG-c>config>mobile>pdn# info
----------------------------------------------
    local-address-assignment
        network-realm "realm-01"
            pool "pool-01"
                ipv4
                    default-gateway first-address
                    micro-net-length 24
                    prefix 192.168.0.0/16
                exit
                ipv6
                    pd
                        micro-net-length 48
                        prefix 2001::/37
                        prefix 192.168.2.0/24
                    exit
                exit
            exit
        exit
    exit
----------------------------------------------

Configure a network realm for the APN.

Configure the network realm for the APN to match the service name of the IES or VPRN service used to host the subscriber session on the BNG-UP. See Service selection for more information about network-realm configuration.

Network-realm configuration for the APN

A:MAG-c>config>mobile>pdn# info
----------------------------------------------
        apn "apn-01"
            network-realm "realm-01"
        no shutdown
----------------------------------------------

For FWA sessions, provision the APN in the UP peer list created in step 3, for the BNG-UPs that can provide service for this APN. The following example shows this configuration.

APN configuration in the UP peer list for FWA sessions

A:MAG-c>config>mobile>profile>pfcp# info
----------------------------------------------
                up-peer-list "ups"
                    peer 192.168.50.84
                        apn “apn-01”
                        exit
                    exit
                    peer 192.168.50.83
                        apn “apn-01”
                        exit
                    exit
                    peer 192.168.50.82
                        apn “apn-01”
                        exit
                    exit
                exit
----------------------------------------------

Configure the ADB.

The ADB configuration determines the authentication process and address assignment method, and also retrieves attributes associated with the subscriber session. The following example uses the ADB to provide the address assignment and the subscriber and SLA profiles for the subscriber session. The address pool refers to the local-address assignment configured in step 5. See Authentication database (ADB), for more information.

ADB configuration

A:MAG-c>config>mobile>profile# info
----------------------------------------------
    authentication-database "auth-db-01"
        match 1 attribute username
            optional
        exit
        entry "default"
            address-assignment
                local-dynamic
                    ipv4-pool "pool-01"
            apn "apn-01"
            ip-anti-spoof true
            subscriber-mgmt
                sla-profile "cup-prof"
                sub-profile "cup-prof"
            exit
            no shutdown
        exit
        no shutdown
    exit
----------------------------------------------

Configure the following, depending on whether you are configuring a fixed-access or FWA session:
- For fixed-access sessions, configure the BNG entry point.
  The BNG entry point informs the MAG-c of the authentication flow and other aspect of how fixed subscriber session are managed and setup. See BNG entry point more information. The following example shows a simple configuration that refers to the ADB configured in step 7.
BNG entry point configuration
```
A:MAG-c>config>mobile>profile#
----------------------------------------------
    bng
        entry-point "bng-entry-01"
            match 1 attribute up-ip
                optional
            exit
            entry "1"
                ipoe
                    authentication-flow
                    adb "auth-db-01"
                exit
            exit
        match
            up-ip 192.168.50.84
        exit
        no shutdown
        exit
        no shutdown
        exit
    exit
----------------------------------------------
```
- For FWA sessions, configure the incoming APN/DNN, according to the GTP Session Establishment Request (4G) or Nsmf_PDUSession_CreateSMContextRequest (5G) messages. This APN informs MAG-c about the authentication flow used for FWA sessions. The following example shows a simple configuration that refers to the ADB configured in step 7.
  Note: If the incoming APN and service APN are the same, it is not necessary to provide the APN via the ADB.
FWA incoming APN configuration
```
A:MAG-c>config>mobile>pdn#
----------------------------------------------
            apn "fwa.mnc01.mcc001.gprs"
                fixed-wireless-access
                    authentication-flow
                        adb "auth-db-01"
                    exit
                    no shutdown
                exit
                no shutdown
            exit
----------------------------------------------
