Frame Relay (Ethernet-based) operations
Ethernet-based (or basic) Frame Relay is also available within the Model 3086FR. This Frame Relay service can
be used in a similar fashion to other Ethernet-based transports within the system such as PPP or the Ethernet
transport. Multiple Frame Relay transports, with different DLCI numbers, can be built upon the HDLC con-
troller that is available with the 3086FR. The Frame Relay Interface is available at the serial interface for trans-
port out of the Ethernet Interface or the ATM link.
Frame Relay Configuration Options
The Frame Relay transport is configurable from both the CLI and the web interface. The following config-
urable variables are available through both interfaces.
Channel Segment Size
The channel segment size is used to define fragmentation of the packets based on the Frame Relay Forum IA
FRF.12. If this variable is set to 0 then FRF.12 “Frame Relay Fragmentation” will be disabled. If set to any
other value it will set the fragmentation size used.
DLCI: Data Link Connection Identifier
The Frame Relay DLCI used for the specified channel. Must be set to a non-zero number as agreed upon by
the Frame Relay connection.
Encapsulation Type
Defines the FRC1490 encapsulation type that will be used by the channel.
Port
Defines the port that should be used to setup the Frame Relay Connection. For routed applications the port
should be set to “frf ”. For bridged applications the port should be set to “fr”.
Rxmaxpdu
Receive side max PDU
Txmaxpdu
Transmit side max PDU
Frame Relay CLI Configuration Options
The following information describes how to configure the frame relay transport on the 3086FR through the
CLI interface.
Build a new Frame Relay Transport
Command: framerelay add transport <name> <port> <dlci>
Add a new frame relay transport to the system
• Name : Any name can be given to the transport. This name will be used to reference the transport in later
commands.
• Port : This variable defines the low layer port that will be used to transport data across the frame relay inter-face.
For routed application the “frf” port should be used. For bridged applications the “fr” port should be used.
