DLP-E176 Edit Path Protection Dual-Ring Interconnect Circuit Hold-Off Timer
Note Cisco recommends that you set the DRI port HOT value to zero and the circuit path selector HOT value
to a number equal to or greater than zero.
Step 1 From the View menu, choose Go to Network View.
Step 2 Click the Circuits tab.
Step 3 Click the path protection circuit you want to edit, then click Edit.
Step 4 In the Edit Circuit window, click the Path Protection Selectors tab.
Step 5 Create a hold-off time for the circuit source and destination ports:
a. In the Hold-Off Timer area, double-click the cell of the circuit source port (top row), then type the
new hold-off time. The range is 0 to 10,000 ms in increments of 100.
b. In the Hold-Off Timer area, double-click the cell of the circuit destination port (bottom row), then
type the hold-off time entered in Step a.
Step 6 Click Apply, then close the Edit Circuit window by choosing Close from the File menu.
Step 7 Return to your originating procedure (NTP).
Purpose This task changes the amount of time a path selector switch is delayed for
circuits routed on a path protection dual-ring interconnect (DRI) topology.
Setting a switch hold-off time (HOT) prevents unnecessary back and forth
switching when a circuit is routed through multiple path protection
selectors.
