DLCI
Parameter Description
DLCI Number Used to identify the DLC. This number is supplied by the Public Frame Relay network
provider. The DLCIs are stored in a table which can be seen with the
L
command.
Frame Relay
Address Map
Determines the method used for mapping the remote IP address to the Permanent
Virtual Circuit.
Static
maps one IP address to this DLCI.
Inverse ARP
maps the IP
address dynamically, in a manner similar to the ARP table.
IP Address Applies when
Frame Relay Address Map
is
Static
. Provides the IP address to be used
for static address mapping.
CIR Committed Information Rate, in percentage of total bandwidth (bandwidth defined in
CONFIG=>INTERFACE=>SWAN =>TRAFFIC CONTROL =>GENERAL
=>BANDWIDTH). Traffic above this rate may be discarded if the network is congested.
Enable Predictor
Compression
Enables data compression using the Predictor algorithm. This feature should be enabled
only if Cyclades' equipment is being used on both ends of the connection because there
is no established standard for data compression interoperability. Data compression is
very CPU-intensive, making this feature effective only for links running at speeds under
1Mbps. At higher speeds, the time necessary to compress data offsets the gains in
throughput achieved by data compression.
Number of Bits for
Compression
Applies when
Predictor Compression Enabled.
Sixteen is fastest, but 10 must be used if
the router on the other end is a PathRouter, for compatibility.
DLCI Priority Level This is the equivalent of CONFIG=>RULES LIST=>IP =>CONFIGURE RULES=>ADD
RULE=>FLOW PRIORITY LEVEL. See the section on traffic control in chapter 12.
Reserved
Bandwidth
This is the equivalent of CONFIG=>RULES LIST=>IP =>CONFIGURE RULES=>ADD
RULE=>RESERVED BANDWIDTH. Defines what percentage of the CIR for an interface
will be set aside for this DLC. See the section on traffic control in chapter 12.
