DLP- D367 Provision a J2 Path Trace on Circuit Source and Destination Ports
Step 3 For the VC12 circuit you want to monitor, verify that the source and destination ports are on a card that
can transmit and receive the path trace string. See Table 20-30 for a list of cards.
Note If neither port is on a transmit/receive card, you cannot complete this procedure.
Step 4 Choose the VC12 circuit you want to trace, then double-click it (or click Edit).
Step 5 In the Edit Circuit window, click the Show Detailed Map check box at the bottom of the window. A
detailed map of the source and destination ports appears.
Step 6 Provision the circuit source transmit string:
a. On the detailed circuit map, right-click the circuit source port (the square on the left or right of the
source node icon) and choose Edit J2 Path Trace (port) from the shortcut menu.
b. Click the 16 byte button.
c. In the New Transmit String field, enter the circuit source transmit string. Enter a string that makes
the source port easy to identify, such as the node IP address, node name, circuit name, or another
string. If the New Transmit String field is left blank, the J2 transmits a string of null characters.
d. Click Apply, then click Close.
Step 7 Provision the circuit destination transmit string:
a. On the detailed circuit map, right-click the circuit destination port and choose Edit Path Trace from
the shortcut menu.
b. In the New Transmit String field, enter the string that you want the circuit destination to transmit.
Enter a string that makes the destination port easy to identify, such as the node IP address, node
name, circuit name, or another string. If the New Transmit String field is left blank, the J2 transmits
a string of null characters.
c. Click Apply.
Step 8 Provision the circuit destination expected string:
a. In the Circuit Path Trace window, enable the path trace expected string by choosing Auto or Manual
from the Path Trace Mode drop-down list:
• Auto—The first string received from the source port is provisioned as the current expected
string. An alarm is raised when a string that differs from the baseline is received.
• Manual—The string entered in Current Expected String is the baseline. An alarm is raised when
a string that differs from the Current Expected String is received.
b. If you set Path Trace Mode to Manual, enter the string that the circuit destination should receive
from the circuit source in the New Expected String field. If you set Path Trace Mode to Auto, skip
this step.
