#### Configuration ID:

  Each time you change and save a unit's configuration, the configuration editor automatically assigns a configuration ID number to the file. The ID format is CYYMMDDS:
  C: indicates the file was created through the configuration editor as opposed to an NMS session. Configuration files created or saved during an NMS session begin with an N. If a file is modified through an NMS session, the unit's status will be magenta, indicating that the configuration file installed on the unit is not the same as the one save in the configuration database.
  YY: represents the year the file was created.
  MM: represents the month the file was created.
  DD: represents the day of the month the file was created.
  S: indicates the file's sequence number beginning with 0.

#### Code Version

  This parameter identifies the product software release code version you want to install on the unit. Each time you install a new version, the program stores it in your management system's RELEASE sub-directory.
  From the pull-down list, select the code version you want to install on the unit. If no versions appear in this list, you need to install the product software release code for the unit you want to add.

#### Description (Optional)

  You can enter up to 255 alphanumeric characters to list the unit's site data or other important information.

#### Command Line & NMS Prompt

  Area at the bottom of the NMS window allowing operator to specify commands to the unit operating system.

####

#### Location (Optional)

  You can enter up to 15 alphanumeric characters in this field to identify the unit's physical location.

#### Contact (Optional)

  You can enter up to 15 alphanumeric characters in this field to specify whom to contact if the unit experiences difficulties.

####

#### My IP Address

  This is the Internet Protocol (IP) address of the local unit. This address identifies the unit during all IP traffic activities and enables the unit to be contacted by other devices in the network.
  Range: 4 numbers (0-255) separated by a period.
  Example: 123.22.33.1

#### Peer IP Address

  If in a SLIP mode, the peer IP address is as defined, however, the unit needs to have this parameter defined. If not connected via SLIP, it does not matter which address is entered into this field, it simply needs to be defined. The default value is 10.10.10.10, which is acceptable if SLIP is not used.
  For documentation purposes, some sites use this field to define the "next hop" IP address. This is a user convention that is not validated. For this reason, it is recommended that you leave the address at its default unless it is being used for SLIP.
  Range: 4 numbers (0-255) separated by a period.
  Example: 123.22.33.3

#### Global IP Address

  This feature supports the management of multiple domains with overlapping sets of IP addresses, from a single management station.
  When set, the management station polls that address, instead of the one specified by the "My IP Address" setting. The unit, itself, is only configured with the private domain address such as My IP address. The management application makes certain all Global IP addresses are unique.
  When the application polls the Global IP address, a Network Address Translation (NAT) gateway translates the IP address from the global address to the private domain address. The unit responds to its private domain address and sends a response back to the NAT gateway. The NAT gateway then substitutes the Global IP address into the message and sends it back to the management workstation. The workstation thinks the unit is globally accessible on the global address, where as the unit is blind to the global address.
  Note: One address pair needs to be configured in the NAT for each unit.
  Range: 4 numbers (0-255) separated by a period.
  Example: 123.22.33.3

#### Network Mask

  Internet Protocol (IP) network mask used for sub-netting. This number "masks" out specific portions of the IP address; the remaining portion of the IP address identifies the network.
  Range: 4 numbers (0-255) separated by a period.
  Example: 255.255.255.0

#### Diagnostic Loop back Timeout

  This value indicates the number of minutes that a diagnostic loop back may run before timing out and automatically terminating. Diagnostic loop backs will not time-out if a value of 0 is entered.
  Range: 0 -- 1440 minutes
  Note: This timer will have no effect on a local unit which has initiated a remote diagnostic loop back. The timer will only effect the unit which has actually put up the loop back path, although, the unit initiating the loop back will still show that a diagnostic condition exists.

#### Maximum Transfer Unit

  Enter the largest size unit (consisting of data characters or bytes normally including synchronization and error control fields) that can pass unfragmented across all intervening IP networks in a datagram's route. A size of 1006, including the header, is recommended.
  Range: 1 -- 1024 bytes.
  Range: 1 -- 1500 bytes (SFrap 3.0, TFrap 3.0, DFrap 3.0 only).

#### Install Transit Delay Table Check Box

  Check box that enables the Transit Delay Table for models Frap 3.0, DFrap 3.0, SFrap 3.0, and TFrap 3.0

#### Frame Relay Traps

  Enable this feature if you want traps for this unit to be sent to the management console.

#### Authentication Traps

  Enable this feature if you want authentication traps sent to the management console.

#### Telnet Access

  Enable this feature if you want to use Telnet to access the unit's command line interface from a remote location via SLIP or in-band DLCI management.

#### Telnet Auto Log out

  Enter the idle time that must elapse before the unit automatically disconnects the Telnet session.
  Range: Disable, 3, 5, 10, 15, 30, or 60 minutes

#### Passwords

  Click this button to configure the unit's access passwords.
