users. If the RADIUS server presents a login challenge which requires a
response, then the TL1 user re-enters the ACT-USER command,
supplying the appropriate response as the password. Challenges and other
reply messages returned from the RADIUS server are displayed as
comments in the response message from the MX2800.
3. TL1 MESSAGES
As stated earlier, TL1 messages are either part of a command-response exchange or are generated autono-
mously. A TL1 command has the general format as follows:
<verb>[-<mod1>[-<mod2>]]:<tid>:<aid>:<ctag>:<general block>:<keyword
block>: <state block>;
Refer to TL1 Commands on page 9-5 for a list of TL1 commands supported by the MX2800.
TL1 Responses
There are three types of TL1 responses:
• Acknowledgment messages
• Output Response messages
• Autonomous messages
Acknowledgment Messages
Acknowledgment messages are brief output messages generated in response to received TL1 commands.
The MX2800 currently supports two types of acknowledgment messages:
• In Progress (IP)
• All Right (OK)
In Progress
The IP acknowledgment message is usually generated as an interim response message to indicate that a
message has been received and the command is being executed. IP messages have the following general
format:
IP <ctag><cr><lf>
<
All Right
The OK acknowledgment message indicates that a command has been received, and the required action
was initiated and completed. This message has the following general format:
OK <ctag><cr><lf>
