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

Parameter Description
SPT epsilon The tolerance used during route calculation to determine which paths
qualify as equal-cost. The range is from 0 – 20.
SPT holddown The interval between two consecutive calculations for generating routing
tables. The range is from 1 (0.1 sec) to 600 (60 sec).
SPT path holddown time The minimum time that can elapse between consecutive calculations that
generate routing tables for border nodes. The range is from
2 (0.2 sec) to 600 (60 sec).
CTD Background Table Displays whether CDT
1
for the background routing table is enabled or
disabled. CTD is the time interval between a cell exiting source node and
entering the destination node.
1. CTD = cell transfer delay
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.
2. CDV = cell delay variation
