THE SG NUM is: 0.

-nrm Maximum number of cells that the source can send for each forward RM-cell. Nrm is

a power of 2 in the range 2–256.

-trm The maximum number of milliseconds for one RM-cell to travel from source to

endpoint. The range is 100 x 2

-7

to 100 x 2

milliseconds.

-cdf Cutoff Decrease Factor (CDF). This controls the decrease in Allowed Cell Rate

(ACR) associated with Missing RM-cell count (CRM). CDF can be either or the

following:

• Zero

• Power of 2 in the range 1/64 to 1

CRM limits the number of forward RM-cells that may be sent in the absence of

received backward RM-cells. CRM is an integer. Its size is implementation specific.

-frtt Fixed Round-Trip Time (FRTT). This is the sum of the fixed delays plus the

propagation delays from the source to the destination and back. The range is

0–16.7 seconds.

-tbe Transient Buffer Exposure (TBE). This is the negotiated number of cells that the

network would like to limit the source to sending during startup periods, before the

first RM-cell returns. The range is 0–16,777,215 cells.

-intvsvd Enable or disable for VS/VD on the internal loop.

• 1 = Off

• 2 = On

• 3 = Unspecified (Unspecified means that the connection takes the on or off status

of VS/VD from the VS/VD specification in the SCT file.) See description of the

cnfintfvsvd command to enable VS/VD at the PNNI port level.

Default: off

-extvsvd Enable or disable for VS/VD on the external loop.
