Chapter9 Troubleshooting Commands tstconseg
tstconseg
Test Connection Segment
Test the integrity of an SVC or SP VC. With tstconseg, a single collection of supervisory cells is sent in
the egress direction betwe en the card and service equip ment (CPE). (See tstdelay for ingress direction.)
When the test successfully starts, the system displays a message stating that the test has begun and
directs you to use either dspcon or dspchantests to see the results. The dspcon command s hows detailed
information about the connection and has a field for the results of this test. The dspchantests command
display only the results of the test.
Note The dspcon fields on the AXSM for round trip delay—including the status of OAM
loopback—always show the re sults of the latest te st and are not chan ge d until a new executio n o f
tstconseg or tstdelay. Therefore, re-executing dspcon does not clear the value for RTD or the
indication that an OAM loopback i s present. The only way to reset the se fields to null is to down the
port (through dnport).
