Table 11: Parameters Available on the Redirection URL from Extreme Campus
Controller to the ECP (continued)
Parameter
Name
Parameter Value Required Notes
hwc_ip Numeric String No This is the IP address to which clients should be
redirected to complete authentication. Typically,
an appliance ends up with many IP addresses,
but only one of them will map to the WLAN
service’s ECP implementation.
Note: This address may not be accessible directly
by the ECP. However, it will be accessible to the
client that is being authenticated.
This attribute appears in the redirection response
from the appliance.
A sample hwc_ip address is “10.10.21.6”.
hwc_port ASCII-encoded
numeric string
No This the port on the appliance interface to which
the client should be redirected. If ECP support is
configured for HTTP then the hwc_port will be
“80”, otherwise it will be “443”.
This attribute appears in the redirection response
from the appliance.
mac ASCII-encoded
hex string
No The MAC address of the client that is being
authenticated. A client could have multiple MAC
addresses. This MAC address is the MAC address
of the client’s wireless interface that it used to
associate to the wireless network.
The client MAC address is in the format of six hex
digits. The hex digits are “0123456789abcdef”.
An example “mac” could be “0023149032a8”.
This is the same value that would be included in
the Calling-Station-ID field of a RADIUS Access-
Request sent on behalf of this client.
role Alphanumeric
String
Yes The name of the access control role to which the
authenticating client is assigned at the moment
of redirection. A best practice is to use the
Extreme Campus Controller default roles.
sn ASCII-encoded
hex string
No The serial number of the AP to which the client
being authenticated associated. The serial
number identifies the AP. It is assigned to the AP
at manufacturing time.
The serial number is a sequence of hex digits
with the ‘alphabetic’ characters in lower case.
“12b2694560000000” is an example of an AP
serial number.
token Alphanumeric
String
Yes An identifier for the user’s wireless session
hosted on the appliance that performed the
redirection.
