Tracing Established Connections
Clear the Connection Trace Buffer
Use the following procedure to clear a specific connection trace:
Step 1 Enter the dspconntracebuffers command at the active PXM45 to view all path traces in the path trace
buffer, as shown in the following example:
M8850_SF.7.PXM.a > dspconntracebuffers
Step 2 Enter the clrconntracebuffer <portid> <vpi> <vci> command to clear the specific connection trace. Replace
<portid> the physical ports id, in the format slot:subslot.port:subport. Replace <vpi> with the port’s VPI,
in the range from 1 through 4095. Replace <vci> with port’s VCI, in the range from 0 through 65355.
clrconntracebuffers 3:1.1:1 -vpi 102 -vci 102
Step 3 Enter the dspconntracebuffer <portid> <vpi> <vci> command to ensure that the specified path trace
buffer is clear. Replace <portid> the physical ports id, in the format slot:subslot.port:subport. Replace
<vpi> with the port’s VPI, in the range from 1 through 4095. Replace <vci> with port’s VCI, in the range
from 0 through 65355.
M8850_SF.7.PXM.a > dspconntracebuffer 3:1.1:1 -vpi 102 -vci 102
M8850_SF.7.PXM.a >
To clear all connection traces in the connection trace buffer, enter the clrconntracebuffers command at
the active PXM45, as shown in the following example.
M8850_SF.7.PXM.a > clrconntracebuffers
Clear the Path Trace Buffer
Use the following procedure to clear a specific path trace:
Step 1 Enter the dsppathtracebuffers command at the active PXM45 to view all path traces in the path trace
buffer, as shown in the following example:
M8850_SF.7.PXM.a > dsppathtracebuffers
Step 2 Enter the clrpathtracebuffer <portid> <vpi> <vci> command to clear a specified path trace. Replace
<portid> the physical ports id, in the format slot:subslot.port:subport. Replace <vpi> with the port’s VPI,
in the range from 1 through 4095. Replace <vci> with port’s VCI, in the range from 0 through 65355.
M8850_SF.7.PXM.a > clrpathtracebuffer 3:1.1:1 -vpi 102 -vci 102
Step 3 Enter the dsppathtracebuffer <portid> <vpi> <vci> command to ensure that the specified path trace
buffer is clear. Replace <portid> the physical ports id, in the format slot:subslot.port:subport. Replace
<vpi> with the port’s VPI, in the range from 1 through 4095. Replace <vci> with port’s VCI, in the range
from 0 through 65355.
