87 NAS-Port-Id A text string with format defined by the aggregation type:
GRE or L2TPv3: “<tunnel-type> rtr-<virtual router id>#lip-<local ip
address>#rip-<remote ip address>”
where
<tunnel-type> = GRE | L2TP,
rtr-<virtual router id> is the transport service
lip-<local ip address> is the local tunnel end-point
rip-<remote ip address> is the remote tunnel end-point
For example: NAS-Port-Id = “GRE rtr-11#lip-50.1.1.1#rip-201.1.1.2”
VLAN: “VLAN svc-<svc-id>[:<vlan>[.<vlan>]]”
where
svc-<svc-id> is the relative identifier of the internal
_tmnx_WlanGwL2ApService Epipe service connecting the WLAN-GW
group interface SAP to the MS-ISA.
[:<vlan>[.<vlan>]] is the optional dot1q or qinq encapsulation identifying the
AP
For example: NAS-Port-Id = “VLAN svc-1:10”
26-3561-1 Agent-Circuit-Id Agent-circuit-id is transparently taken from the circuit-id in DHCP option-82.
Most WIFI access-points insert information describing the AP and SSID that
the UE is associated with. Recommended format is an ASCII string
containing AP’s MAC@, SSID name and SSID type (open or secure), with a
delimiter between each, as shown in example:
“00:00:00:00:00:01;xfinity-wifi;o”
26-6527-145 Alc-MGW-Interface-
Type
This contains the interface type that will be used to determine the type of
GTP-C connection, overrides local configuration.
26-6527-146 Alc-Wlan-APN-Name Specifies the Access Point Name (APN) for which a GTP-C session will be
set up. This will be signaled in the GTP-C setup and may be used to determine
the IP address of the GGSN/P-GW by performing a DNS query if the [26-
10415-5] 3GPP-GGSN-Address attribute is not present. This overrides a
locally configured APN.
26-6527-147 Alc-MsIsdn Contains the MSISDN (telephone number) of the UE, and will be included in
GTP-C signaling. When not present the corresponding GTP-C Information
Element will not be sent.
26-6527-148 Alc-RSSI Received Signal Strength Indication. Used in conjunction with the radius-
proxy track-accounting feature. When the radius-proxy receives this attribute
in an accounting message, it will be copied into the DHCP lease state and
echoed by the SROS accounting.
26-6527-149 Alc-Num-Attached-
Ues
Number of attached WIFI UEs. The attribute is forwarded by the RADIUS
proxy when received in an Access-Request from the AP.
