Managing NCDP Clock Sources
Configuring an NCDP Port
Once you enable NCDP on your node, NCDP is automatically enabled on all the node’s NNI ports. You
can alter the default NCDP port configuration through the cnfncdpport <portid> <options> command,
as shown in the following example:
M8850_LA.8.PXM.a > cnfncdpport 1:2.2:2 -ncdp enable -vpi 1 -vci 1 -admincost 1 -pcr 200
-scr 100 -mcr50
Table 7-15 describes the cnfncdpport command options.
Table 7-15 cnfncdpport Command Parameters
Parameter Description
portid Port identifier in the format slot:bay.line:ifnum.
These parameters are described in Table 7-1.
-ncdp Enables/disables NCDP on the current port.
Default = disable
-vpi Reserved VPI of the signaling channel, in the
range from 0 through 4095. There is no reason to
change this number unless a relevant card’s
partition is intended to support a specific VPI.
Note If you change the VPI, it must be within
the valid partition range or it will be
disabled.
Default = 0
-vci Reserved VCI of the signaling channel, in the
range from 32 through 65535. Normally, no
reason exists to change it.
Note If you change the VCI, it must be within
the valid partition range or it will be
disabled.
Default = 34
-adminCost Sets the routing cost of the port, in the range from
1 through (2^24-1).
For example, if the equipment were in an area
with a large amount of electronic noise, or if the
switch carried a particularly large amount of
traffic, you might want to raise the cost.)
Default = 10
-pcr Specifies the peak cell rate (PCR) for the port.
Default = 250 cells per second
