tstdelay
tstdelay
Test Delay—AXSM, AXSM-E, AXSM-32-T1E1-E, AXSM-XG
Test the integrity of the connection in the ingress direction by sending a collection of supervisory cells
to the remote end of the network and back. (See tstconseg for the egress direction.) The tstdelay
command applies to only SPVCs.
If the test successfully begins, the display states the fact and directs you to use the dspcon or
dspchantests command to view the round trip time in microseconds. The dspcon display shows detailed
information on the connection and has a field for the test results. The dspchantests display shows the
results of only the round trip delay test.
Note The dspcon fields on the AXSM for round trip delay—including the status of OAM 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).
Note The primary purpose of tstdelay is to test the integrity of the connection. The round trip time is not
accurate enough for any use that requires an accurate measurement of delay.

Attributes
ifNum The logical port number. The ranges are:
• AXSM: 1–60
• AXSM-E: 1–32
• AXSM-XG: 1–126
vpi Virtual path identifier. On the AXSM, the range is 1–255.
vci Virtual connection identifier. On the AXSM, the range is 1–65535 for a VCC. For a VPC,
the vci is 0.
-num (Optional) Specifies the number of times a collection of supervisory cells should traverse
the SVC for the current execution of tstdelay.
