Note:      Depending upon your product type, this dialog may vary. This help context covers all possible configuration parameters. If your dialog does not contain certain parameters, they don't apply to the product you are configuring.

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.
X.21 clocking must be used for X.21 interfaces.
Range: Internal, External, X.21 Internal, X.21 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

Enable this feature if you are using multiple flags to separate each frame. If enabled, this feature inserts two or more flags between frames.
Note: This feature must be enabled if a port is doing several retransmission.
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.
 
This value should be set to half of that set for n2.
Range: 0 -- 15
 

RNR Timeout

This value determines how long the unit will receive "Receiver not Ready" (RNR) frames from the session partner before disconnecting the session.
Range: 0 ~ 15 seconds
 

DTR Initiated Backup

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