R3303-HP HSR6800 Routers Layer 2 - WAN Command Reference

132
On a DTE main interface, the device automatically creates virtual circuits according to the settings
received from the DCE side. If you do that manually, make sure the DLCIs of the virtual circuits are
identical to those used on the DCE.
On a DTE subinterface, you must manually create the virtual circuits.
Examples
# Assign a virtual circuit with DLCI 100 to frame relay interface Serial 2/0/0.
<Sysname> system-view
[Sysname] interface serial 2/0/0
[Sysname-Serial2/0/0] fr dlci 100
[Sysname-fr-dlci-Serial2/0/0-100]
fr inarp
Use fr inarp to enable InARP for frame relay on the interface.
Use undo fr inarp to disable InARP for frame relay on the interface.
Syntax
fr inarp [ ip [ dlci-number ] ]
undo fr inarp [ ip [ dlci-number ] ]
Default
InARP for frame relay is enabled.
Views

Default command level
2: System level
Parameters
ip: Performs InARP for IP addresses.
dlci-number: Data link connection identifier number (virtual circuit number), indicating that the inverse
address resolution is performed for this DLCI number only, is in the range of 16 to 1007.
Usage guidelines
When frame relay sends data over the interface, the peer IP address must be mapped to the local DLCI
number. Such a mapping can be configured manually, or automatically through InARP.
To enable or disable InARP for all virtual circuits of interfaces, use the command without any parameter.
To enable or disable InARP for the specified virtual circuit, use the command with the dlci-number
argument.
Enabling InARP on an interface or subinterface also enables InARP on all virtual circuits of the interface
or subinterface. To disable InARP on a specific virtual circuit of the interface or subinterface, use undo fr
inarp ip dlci-number command.
Using the undo fr inarp command to disable InARP on an interface also disables InARP on all virtual
circuits on the interface. To enable InARP on a specific virtual circuit of the interface, use the fr inarp ip
dlci-number command.
The fr inarp command configured on an FR main interface also applies to its subinterfaces.
