tstconseg

Test Connection Segment
Test the integrity of an SVC or SPVC. With tstconseg, a single collection of supervisory cells is sent in
the egress direction between the card and service equipment (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 shows 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.
The dspcon fields on the AXSM for round trip delay—including the status of OAM
Note
loopback—always show the results of the latest test and are not changed until a new execution of
tstconseg or tstdelay. Therefore, re-executing dspcon does not clear the value for RTD or the
indication that an OAM loopback is present. The only way to reset these fields to null is to down the
port (through dnport).
