IBM SC30-3681-08 Cir-monitor, Congured with theadd permanent-virtual-circuit or add, Compression

Con®guring Frame Relay Interfaces

switched-virtual-circuits

throttle-transmit-on-fecn

cir-monitor

Disabling this feature allows the circuit's information rate to exceed the

maximum information rate that is calculated using the parameters

con®gured with theadd permanent-virtual-circuit or add

switched-virtual-circuitcommand. The default setting for this feature is

disabled. See ªCircuit Congestionº on page 399 for more information.

cllm Disables the device from throttling down in response to a CLLM message.

The default is disabled. See ªCircuit Congestionº on page 399 for details.

compression

Disables compression on the interface. Compression will not be performed

for any VC.

congestion-monitor

Disables the congestion monitoring feature. Disabling this feature prevents a circuit's information rate from varying in response to congestion between the minimum information rate and the line speed. See ªCircuit Congestionº on page 399 for more information. The default setting for this feature is enabled.

dn-length-®eld

Prevents inter-operation with implementations of DECnet Phase IV over Frame Relay that require a length ®eld to precede DECnet packets in Frame Relay frames, but allows inter-operation with DECnet Phase IV Frame Relay software that does not use a length ®eld before the DECnet packet. Disabling dn-length-®eld causes Frame Relay not to insert a length ®eld into transmitted frames containing DECnet packets and not to attempt to remove the length ®eld from received frames containing DECnet packets.

Note: This option is presented as a con®guration option only

encryption

Disables encryption on the interface. Even though the PVCs on this interface may be encryption capable, encryption will not take place.

lmi Disabling this parameter allows for normal operation or end-to-end Frame Relay testing in the absence of a real network or management interface. With end-to-end Frame Relay testing, it is necessary to add like PVCs (the same PVC number, such as 16 and 16) on both ends of the link.

lower-dtr

This parameter determines how the data terminal ready (DTR) signal is handled for leased serial-line interfaces on the router. It is not supported on Frame Relay dial circuit interfaces. See the enable lower-dtrcommand for a more complete description of the lower-dtr parameter.

The following cable types are supported:

EIA 232 (RS-232)

V.35

V.36

The default setting is disable lower-dtr.
