Displaying Node Configuration Information
Displaying the SVCC RCC Timer
Enter the dsppnni-svcc-rcc-timer command to display SVCC-based RCC variables.
mgx8830a.1.PXM.a >
dsppnni-svcc-rcc-timer
The following example shows the report for this command:
mgx8830a.1.PXM.a >
dsppnni-svcc-rcc-timer
node index: 1
Init time........... 4 Retry time.......... 30
Calling party integrity time... 35
Called party integrity time.... 50
shows the objects displayed for the dsppnni-svcc-rcc-timer command.
Load balance
Defines the load balancing rule if alternative
equal-cost routes exist for a given call request.
Ondemand Routing
The on-demand routing rule, which is either
firstfit or bestfit. Firstfit routing selects the first
route found that goes to the selected destination.
Firstfit route search time is minimized, but the
selected route is not optimum. Bestfit routing
selects a route based on the least-cost. The
average route- search-time is greater, and more
CPU-intensive, but the optimum route is selected.
AW Background Table
Displays whether the maximum cost (total AW)
for the background routing table is enabled or
disabled.
CDV Background Table
Displays whether CDV
22
for the background
routing table is enabled or disabled. CDV is a
component of cell transfer delay, and is a quality
of service (QoS) delay parameter associated with
CBR and VBR service. Cell Delay Variation is the
variation of delay between cells, measured peak to
peak.
1.
CTD = cell transfer delay
2.
CDV = cell delay variation

Parameter
Description
node-index
The node index assigned to a PNNI logical node on a network. The
range is from 1 to 65535.
Init time
The amount of time (in seconds) this node will delay advertising its
choice of preferred an SVCC to a neighbor with a numerically lower
ATM address, after determining that such an SVCC should be
established. The range is from 1 to 10.
