#### DLCI Length

  This field defines the length of the Frame Relay address packet in bytes.
  Range: 2, 3, or 4 bytes

#### CRC Mode

  Cyclic Redundancy Check mode. This is the action performed by the unit when packets containing CRC errors are received.
  If set to Discard, frames containing CRC errors will be appended with an abort sequence. If Pass through is selected, frames containing CRC errors will be passed through.
  Range: Discard, or Pass through

#### INARP Timer

  This value defines the InARP timer that represents how often the unit generates an InARP query. This feature enables the unit to identify its router and can be configured to periodically generate its own InARP inquiries. Responses to these InARP inquiries supply IP addresses to previously identified unit DLCIs. The unit generates InARP inquiries at the rate specified by this timer.
  Range: 5 -- 86400 seconds

#### Address Resolution Mode

  This field identifies resolution protocols that are recognized and used by the unit to eliminate dependence on static routing tables that correlate the relationship between DLCIs and IP addresses.
  Range: Single DLCI, All DLCIs, All DDS DLCIs, or All DTE DLCIs (D-FRAP 3.0 Only)
  Range: Inactive, ARP on Man DLCI, INARP on Man DLCI, Both on Man DLCI, Both on All DLCIs, Both on DDS DLCIs, and Both on DTE DLCIs (FRAP 3.0 Only)
  Range: Single DLCI, All DLCIs, All To-DCE DLCIs, or All To-DTE DLCIs (S-FRAP 3.0 Only)
  Range: Inactive, ARP, INARP, or Both ( Other Models)
  If set to Inactive, the unit disables all forms of its address resolution. The unit will not respond to either ARP or InARP requests for DLCI and IP information.
  If set to ARP, the ARP form of address resolution is enabled. This form is used when an IP address is known but not its DLCI. Exchanged ARP queries and replies supply this information.
  If set to INARP, the InARP form of address resolution is enabled. This form is used when a DLCI is known but not its IP address. Exchanged InARP queries and replies supply this information.
  If set to Both, both ARP and InARP forms of address resolution are enabled. The unit will automatically respond to requests for DLCI and IP information.
  If set to Single DLCI, system is enabled to connect to a single DLCI.
  If set to All DLCIs, system is enabled to connect to all available DLCIs.
  If set to All DDS DLCIs, system is enabled to connect to all available DDS DLCIs.
  If set to All DTE DLCIs, system is enabled to connect to all available DTE DLCIs.

#### Management DLCI Value

  This field reflects the DLCI value used to transport the the unit's in-band management traffic.
  If the in-band management traffic is Local, the DLCI number identifies a private virtual circuit between the unit and the DTE, and is used for both LMI Spoofing and LMI Sourcing.
  If the in-band management traffic is Remote, the DLCI number identifies a private virtual circuit between the unit and its carrier switch, and is used for both LMI Spoofing and LMI Sourcing.
  If the in-band management traffic is Bidirectional, the DLCI number identifies the private virtual circuits between the unit and its DTE, and between the unit and its carrier switch. The DLCI number is also used for LMI Sourcing.
  If the in-band management traffic is Piggybacked, the DLCI number identifies a shared virtual circuit between the carrier switch and the DTE. This virtual DLCI circuit carries both management traffic and application traffic (multiplexed), and is used for LMI Sourcing and address resolution (InARP & ARP).
  Note: Do not assign an in-band management DLCI of 1023 if the LMI type is configured for Type-1, or DLCI 0 if LMI type is configured for Annex-D or Annex-A.
  Range: 0 -- 1023

#### Management DLCI Mode

  Range: Inactive, ARP, INARP, or Both (D-FRAP 3.0)
  Range: Inactive, Local-To-DTE, Remote-To-DCE, Bidirectional, Piggyback, or Fixed DCE (S-FRAP 3.0)
  Range: Inactive, Local, Remote, Bidirectional, or Piggyback (Other Models)
  If Inactive is selected, In-band DLCI management is disabled. Remote management may be achieved through SNMP (SLIP via the COMM port), or Telnet
  If ARP is selected, Management DLCI Mode is set for ARP Configuration
  If INARP is selected, Management DLCI Mode is set for INARP Configuration
  If BOTH is selected, , Management DLCI Mode is set for both ARP and INARP Configuration
  If Local is selected, in-band management traffic is carried on a private virtual DLCI circuit established between the Probe and the DTE device.
  If Remote is selected, management traffic is carried on a private PVC established between the unit and the carrier switch.
  If Bidirectional is selected, management traffic is carried on a private PVC established between the unit and the carrier switch, and between the unit and its DTE device.
  If Piggyback is selected, management traffic is carried on any existing PVC (in a "piggyback" fashion) which passes through the Probe between the DTE device and the carrier switch.
  Note: Management traffic is assigned a lower priority than application traffic. If in Piggyback mode, you may experience management delays during periods of heavy application traffic.

#### Management Data Discard Eligibility

  This field allows Management Data Discard
  Range: Yes or No

####

#### Management DLCI Encapsulation Type

  This field defines the form of IP encapsulation used on in-band DLCI management traffic.
  Note: In most cases, selection "Auto" should be used.
  Range: RFC1490-IP, RFC1490-SNAP, Auto, or Cisco
  Select RFC1490 for Network Level Protocols using the IP encapsulation technique.
  Select RFC1490Snap for Sub-network Access Protocols using the SNAP encapsulation technique.
  Select Auto if you want the unit to automatically recognize all forms of encapsulation upon receipt and adjust this setting as needed.
  Select Cisco to use their proprietary encapsulation technique.

#### LMI Type

  Select the LMI type used by your Frame Relay connection.
  Note: The actual DLCI number which carries LMI traffic is dependent on the type of LMI configured. DLCI 0 carries LMI traffic if Annex-D or Annex-A is selected. DLCI 1023 carries LMI traffic if Type-1 is selected.
  Range: Annex-D, Annex-A, or Type-1 (LMI or Cisco), Auto-Sense (SFrap 3.00, TFrap 3.00, DFrap 3.0).

#### LMI Inactivity Timeout

  This value defines the LMI inactivity time-out value (in seconds). LMI sourcing is active once a value has been configured. Sourcing commences if an LMI status message is not detected on either the DTE or network interface for a period of time equal to or exceeding the value entered in this field.
  To disable LMI sourcing, enter the value of 0.
  Range: 0 -- 255 seconds (D-FRAP 3.0,FRAP 3.0 , and S-FRAP 3.0 Only)
  Range: 0 -- 255 seconds, or 0 -- 63487, depending upon the type of Probe you are configuring ( Other Models)

#### LMI Keep Alive Timeout

  This value defines the LMI keep alive value (in seconds). This value represents how often LMI status/inquire messages are generated while LMI sourcing is active. The unit generates LMI status inquiries at the rate specified by this timer.
  Range: 0 -- 255 (D-FRAP 3.0 only)
  Range: 0 -- 3600 (S-FRAP 3.0 only)
  Range: 0 -- 63487

#### LMI Full Status Rpt. Timer

  This field defines the LMI Full Status Report Timer. The unit monitors LMI traffic for full status reports. If it detects that a full status report has not been exchanged between its DTE and network ports within the interval specified by this timer, it issues Traps that report the inactivity of all DLCIs, and activates LMI sourcing.
  To disable this feature, enter the value of 0.
  Range: 20 -- 3600 seconds (FRAP 3.0 Only)
  Range: 0 -- 63487 seconds (Other Models)
