–
Rate Up: Specifies the increment in cell rate when the rate goes up. The Foresight Rate Up
increment is in cells per second per adjustment
–
Rate Down: Specifies large reductions in the transmit/receive cell rate. This ForeSight Rate
Down value is a percentage of the current rate.
–
ADTF/IcrTimeout(millisec): Allowed-cell-rate Decrease Time Factor/Initial-cell-rate
Time-out. The time between RM cells before the allowable cell rate returns to the initial cell
rate.
–
TRM/MinAdjust Period(millisec): Time RM/Minimal Adjustment Period. The maximum
amount of time between RM cells on an ABR connection.
• Connection Descriptor
–
The connection descriptor is independently configurable at each end of a connection. Character
Limitations: None. Range: The Descriptor field will take any number of characters, but will
only display 64. To activate the Connection Descriptor feature, the following configuration
steps will need to be followed. Using the command line interface (CLI) as user svplus:
a. cd/usr/users/svplus/conf
b. vi CwmDomainGlobal.conf
# Cwm Global Across the Domain Configuration File
# <Name> = <Value>
DESCRIPTOR_FLAG=0 (on=1, off=0)
c. Change the flag to 1 (on)
d. write and quit the file (:wq!)
e. Stop and restart the CWM core.
• Routing Parameters
–
Avoid Trunk Type: This type is applicable only when a connection involves multiple routing
nodes. Routing is not involved when a connection originates and terminates on the same routing
node. That is, when originating and terminating endpoints are using the same routing node, this
parameter is not applicable and is made insensitive. (Greyed out).
–
Reroute Priority: This type is applicable only when a connection involves multiple routing
nodes. Routing is not involved when a connection originates and terminates on the same routing
node. That is, when originating and terminating endpoints are using the same routing node, this
parameter is not applicable and is made insensitive. (Greyed out).
–
Enable Cell Routing: Enables Cell Routing on a connection.
–
Use Trunks Using ZCS: This type is applicable only when a connection involves multiple
routing nodes. Routing is not involved when a connection originates and terminates on the same
routing node. That is, when originating and terminating endpoints are using the same routing
node, this parameter is not applicable and is made insensitive. (Greyed out).
–
Preferred Route: This type is applicable only when a connection involves multiple routing
nodes. Routing is not involved when a connection originates and terminates on the same routing
node. That is, when originating and terminating endpoints are using the same routing node, this
parameter is not applicable and is made insensitive. (Greyed out).
–
Override CAC: Connection Admission Control. An ATM function which determines whether a
virtual circuit VC) connection request should be accepted or rejected. Override CAC allows an
override option for this function.
–
Route Master: The initial point of a route request.
–
Current Route: The current traffic route.
