Parameter Description Range / Defaults
password The password of the user for authentication. —
session_timeout The role will be changed to a pre-auto role after
session timeout.

authentication Authentication method used to authenticate the
message and the sender. You can use any of MD5,
SHA-1 or clear text methods of authentication. This
option is ignored if shared secret is not configured. It
is, however, mandatory if it is configured.
key This is the encoded MD5/SHA-1 hash of shared
secret or plain text shared secret. This option is
ignored if shared secret is not configured on the
switch. The actual MD5/SHA-1 hash is 16/20 bytes
and consists of binary data. It must be encoded as an
ASCII-based HEX string before sending. It must be
present when the VC is configured with an xml API
key for the server. Encoded hash length is 32/40
bytes for MD5/SHA-1.
version The version of the XML API interface available in the
VC. This is mandatory in all XML API requests.
Current version is XML
API 1.0
CALEA Integration and Lawful Intercept Compliance
Lawful Intercept (LI) allows the Law Enforcement Agencies (LEA) to perform an authorized electronic
surveillance. Depending on the country of operation, the service providers (SPs) are required to support LI in
their respective networks.
In the United States, SPs are required to ensure LI compliance based on Communications Assistance for Law
Enforcement Act (CALEA) specifications.
Instant supports CALEA integration in a hierarchical and flat topology, mesh W-IAP network, the wired and
wireless networks.
Enable this feature only if lawful interception is authorized by a law enforcement agency.
CALEA Server Integration
To support CALEA integration and ensure LI compliance, you can configure the W-IAPs to replicate a specific or
selected client traffic and send it to a remote CALEA server.
Traffic Flow from W-IAP to CALEA Server
You can configure a W-IAP to send GRE-encapsulated packets to the CALEA server and replicate client traffic
within the GRE tunnel. Each W-IAP sends GRE encapsulated packets only for its associated or connected clients.
The following figure illustrates the traffic flow from the W-IAP to the CALEA server.
