Sample

Parser Variable

string

Match any single word.

Device hostname can be parsed by parser with string variable, such as hostname CA-TOR-SW1 --> Hostname $hostname (string).

mstring

Match one or multiple words.

	Note: A mstring variable cannot be followed by another mstring variable.

device neighbor can be parsed by parser with mstring variable.

int

Match any whole number.

float

Match any double-precision IEEE 64-bit (8-byte) floating-point number.

Device version can be parsed by parser with string variable, such as Version 15.4 --> Version $version (float).

table

Match any information that can be converted into a table.

Device ip route can be parsed by parser with table variable.

Intent Variable

Compound variable can convert the single variable into different formats or calculates new variables using two or more existing single variables.

Compound table can merge two table variables in the same NI into one table variable, including merged table, sub table, and appended table.

Macro variables are variables with a pre-defined default value.

Task variable is a global variable, which can be used in the Triggered Automation Framework (TAF), auto intent, and bot.

All variables in diagnosis If condition can be automatically collected as critical variables to qualify devices in NIT.

Signature variables are available to be added to table column in ADT building from NIT.

The device built-in data are supported in intent, such as Route Table, Topology Table, and NCT.

ADT is an extended global data table for managing the critical network assets and network intents associated with those network assets.

Intent variable is defined at the intent level (string, number, or table variable).

Built-in Variable

such as $this_device, $device_name.
