Speed

Virtual Bridge Number

Virtual Ring Number

  The following parameters are defined for DSU/CSU ~ Frame Relay connections:

NAU Name

  This optional name enables you to assign a name to the port. NAU names must be unique to the unit.
  Range: Up to eight characters (A-Z, 0-9, @, #, $)

Port Initially Enabled

  This option determines whether or not the port is enabled at system startup. If disabled, the port must be started manually by an operator.
  Range: Enabled or Disabled

Clocking

  This parameter defines the port's clocking.
  Internal clocking enables the unit to emulate a physical DCE interface
  External clocking enables the unit to emulate a physical DTE interface
  Range: Internal, or External

Speed

  If the port provides clocking, this parameter sets the speed at which the link and attached devices operate.
  If clocking is external, the link runs at the speed of the clocking device, up to the unit's maximum rate. For the best line performance, the speed should match that of the actual link.
  Range: Any speed available from the pull-down list

Signal Control

  This option enables you to define the physical settings used to determine the port's status.

Multiple Flag Separation

  This switch defines whether or not the port will use multiple flag separation.
  Range: Enabled or Disabled

Virtual Ring Number

  This value defines the virtual ring number assigned to the frame relay WAN. This value must be unique to the network. If possible, leave it set to 2. If you assign another number, factory-fresh units will have an additional hop.
  Do not assign numbers 1 or 3, they are reserved for factory-fresh units.
  Range: 001 -- FFF

Virtual Bridge Number

  In most cases, this value should not be changed. It defines the virtual bridge number for the WAN.
  Range: 1 -- 15

Local Management Protocol

  This protocol must match the one used by the network.
  Range: Annex A, Annex D, or LMI

Link Polling Timer (T391/nT1)

  This timer determines how frequently the unit sends a full status inquiry message to the frame relay network.
  Range: 5 -- 30 seconds (in increments of 5)

Full Status Polling Count (N391/nN1)

  This value defines the number of polling intervals that must expire before transmitting a Full Status request message.
  Range: 1 -- 255 intervals

LLC Parameters

  These values may be adjusted to fine-tune the ports performance.

LLC2 Frame Format

  This parameter enables you to specify which LLC2 frame format the frame relay link can use.
  Range: Token Ring, Ethernet Version 2, IEEE 802.3, or All

IP Parameters

  These parameters must be defined if you intend to use IP or SNMP.

Enabled Inter-Unit Session Resiliency

  Enable this feature if you have redundant FRADs configured on the host end.
  Range: Enabled or Disabled

Session Switch Threshold

  The remote FRAD maintains a session switch time-out counter for each session. When this counter equals the configured session switch threshold, this feature switches sessions with the same internal ring number from the primary to the parallel route. This is similar to a PVC failure. Sessions that do not have a parallel route defined are terminated immediately.
  This parameter enables the detection of a lost virtual route. When traffic exceeds this threshold, the remote FRAD tries the parallel route. If the parallel route is also down, the remote FRAD tries the alternate route.
  Range: 0 -- 15

DTR Initiated Backup

  Click on this button if you intend to use dial backup as an alternate route.
