Chapter4 Connection Manager PVC Connections Supported by Release 10 of CWM
Note In this release, Multicast connections are not supported from the Connection Manager GUI.
Table 4 -11 lists the cards that belong to the various endpoint card types.
Modifying Connection Parameters
From the Connection Management main window, select a node and click the Apply button to view
connections and the status of c on n ect io ns on t he sel ected node. Select a connectio n w ith a s ta tu s o f
“O.K.” Click the Modify button at t he b ottom of this screen to br in g up a modification window for the
selected connection. The new Mod i fy C on n ect io n w in dow d is p la ys information about the selected
connection, and presents edita ble parameters in the far righ t c ol umn o f th e screen.
You can expand or collapse the Modify Connection and All Parameters windows by clicking the right
and left arrows at the top of the screen in between these windows.
For an ATM-ATM connection with VBR Service Type, the editable c onn ect ion parameters are as
follows:
•Ingress UPC Parameters
–
PCR0-1(cps): Peak Cell Ra te- A value that defines a rate l imitation for ATM traffic used in the
ingress policing algorithm. In ge ne ra l, traffic arriving at rates greater than the P C R a re
discarded.
–
CDVT0+1(usec): Cell Delay Variation Tolerance for the first leaky bucket, which applies to
cells with CLP(0+1). CDVT is th e m a ximum time for accumulat ed v io lat ions of cell-arrival
time parameters.
–
SCR0+1(cps): Sustainable Cell Rate- The guaranteed sustainable rate for an ATM connection.
Associated with the policing function used on ingress for VBR and ABR connections.
–
MBS(cells): Maximum Burst S ize in cells. This is the maximum numbe r of cells that may burst
at the PCR but are still com pl ia nt . Th is is u sed to determine the Burs t Tolerance (BT) which
controls the time scale over w h ich t he S u s tai ne d Cell Rate (SCR) is polic ed..
