Subscriber ID and Lookup Fields

In VTA Configuration Manager, you can edit the following fields in the Subscriber ID and Lookup screen.

VTA Subscriber ID

• Data key that identifies subscriber accounts and sessions in the VTA database. Some settings also provide information that the NIC and the SAE use to identify subscribers. For more information, see Table 31.
• Value—One of the following data keys:

• LOGIN_NAME— Login name (JUNOSe routers only), which is the data key for the VTA database, the NIC, and the SAE
• USER_DN—Subscriber DN, which is the data key for the VTA database, the NIC, and the SAE
• INTERFACE_NAME@ROUTER_NAME—Interface name and virtual router

• Provides the ROUTER_NAME data key for NIC
• Provides the INTERFACE_NAME data key for SAE

• INTERFACE_ALIAS—Interface alias
• INTERFACE_ALIAS@ROUTER_NAME—Interface alias and virtual router
• USER_MAC_ADDRESS—Subscriber MAC address
• PRIMARY_USER_NAME—Primary login name
• PORT_ID@ROUTER_NAME —NAS port ID and virtual router (JUNOSe router only)
• ACCOUNTING_ID—Accounting ID, which is the data key for the VTA database and the NIC. The NIC uses ACCOUNTING_ID to look up the SAE, and it returns SAE references and subscriber IP address. The VTA uses the returned IP address as the SAE data key.

• Guidelines—LOGIN_NAME, USER_DN, and INTERFACE_NAME@ROUTER_NAME also provide data keys for the NIC and the SAE; the other settings do not.
• Default—LOGIN_NAME

VTA NicProxy Namespace

• If you are using a NIC to map subscriber identifiers to an SAE, and you select a VTA subscriber ID value that provides a data key for the NIC, specify the NIC proxy that uses that data key.
• Value—Location of the NIC proxy configuration relative to the configuration properties for the VTA.
• Guidelines—To cause the NIC to look up the SAE using the accounting ID, configure /NicProxies/AcctIdToSaeNicProxy.
• Default—/Nic/Proxies/IdToSaeNicProxy

SAE Subscriber Lookup

• Data key that uniquely identifies the subscriber in your SDX configuration. The VTA uses this data key to identify a subscriber session or service session when it receives a plug-in event. For more information, see Table 32.
• Value—One of the following data keys:

• USER_IP_ADDRESS—Subscriber IP address (JUNOSe routers only)
• USER_DN—Subscriber DN
• LOGIN_NAME —Login name (JUNOSe router only)
• INTERFACE_NAME@ROUTER_NAME—Interface name and virtual router
• PRIMARY_USER_NAME—Primary login name

• Default—Subscriber IP address
