Login State

For security reasons, access to Alcatel-Lucent ITM-SC is protected by a login process. Alcatel-Lucent ITM-SC sends a denial message and drops the connection if the login process fails. The following section describes the login protocol.

Lucent ITM-SC Login

The Probe for Alcatel-Lucent ITM-SC initiates the communication to Alcatel-Lucent ITM-SC by setting up the TCP/IP connection and sending out a login request message.

The format of the Alcatel-Lucent ITM-SC login message is:

logreq
i2000_tid <string>
dscan_tid <string>
dscan_version <string>
msgno <string>
<012><012><012>

The following table describes the login request fields and corresponding values.

Table 1. Lucent ITM-SC Login Request and Response Fields
Field Name	Values	Description
`i2000_tid`	`string`	Lucent ITM-SC hostname.
`dscan_tid`	`string`	Identifier.
`dscan_version`	`string`	Version.
`msgno`	`long integer`	Message number.
`i2000_version`	`string`	Lucent ITM-SC version.
`time`	`long integer`	Time.
`stat`	`C \| D \| S`	Status. Possible values are: `C`: Login completed `D`: Login denied `S`: Login suspended
`errcode`	`string`	Error code.

The Alcatel-Lucent ITM-SC responds with a login response message. The format of the response is:

logrsp
i2000_tid <string>
dscan_tid <string>
i2000_version <string>
dscan_version <C | D | S>
time <string>
msgno <>
stat <>
errcode <>
<012><012><012>

Communication is terminated by disconnecting the TCP/IP communication link. A new session may be started by the client by re-establishing the TCP/IP connection and completing a login procedure.

On successful completion of the Login state, the probe proceeds to the Initialization state.
