# Informational keywords

This topic describes read-only keywords for retrieving information. Do not edit the keywords listed in this topic. Use these keywords for retrieving information about the:

- Board

- Driver

- Miscellaneous board information

- EEPROM

## Retrieving board information

Keyword | Type | Description
--- | --- | ---
State | String | State of the physical board.

## Retrieving driver information

Keyword | Type | Description
--- | --- | ---
Driver.BoardID | Integer | Number used by the CG board driver to refer to this board. Two boards accessed by different drivers can have the same driver ID number.
Driver.Name | String | Operating system independent name (the root name) of the board driver.
SwitchDriver.Name | String | Operating system independent name (the root name) of the board switching driver.

## Retrieving miscellaneous information

Keyword | Type | Description
--- | --- | ---
NetworkInterface.T1E1[x].ISDN.NFAS_Member.Count | Integer | Number of interfaces in this NFAS group. The value is calculated based on the number of T1E1[x].ISDN.NFAS_MEMBER[y] structures specified.
NetworkInterface.Ethernet[x].MAC_Address | String | Specifies the MAC address.

## Retrieving EEPROM information

The data type for all EEPROM keywords is Integer.

Keyword | Description
