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 APs 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”
26-6527-148 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.
For authentication originated by the WLAN GW, this attribute contains
the total number of UEs that are currently attached to this UE’s tunnel.
This can be used to detect if this is the first UE on a tunnel (value 1). For
non wlan-gw/vRGW UEs this value will be 0. Inclusion can be
configured by adding the option wifi-num-attached-ues in configure
subscriber-mgmt authentication-policy name include-radius-
attribute for ESM, and in configure aaa isa-radius-policy name auth-
include-attributes for DSM.
26-6527-172 Alc-Wlan-Portal-
Redirect
Used when authenticating migrant hosts. When an access-accept
contains this attribute, the host will stay in migrant phase, but will have
limited forwarding capabilities. All filtered (not allowed) http-traffic will be
redirected to a specified portal URL. This attribute must contain the
name of a redirect policy configured under configure subscriber-
mgmt http-redirect-policy policy-name which will specify a set of
forwarding filters.
It is also allowed to just send an empty Alc- Wlan-Portal-Redirect VSA
to force a redirect with the configured policy and url.
2 6 - 6 5 2 7 - 1 7 3 A l c - W l a n - P o r t a l - U r l I f a m i grant host is redirected, specifies the URL it has to be redirected
to, takes precedence over the URL configured in the redirect policy
under configure subscriber-mgmt http-redirect-policy policy-name.
