DLP- F301 Edit SNCP Dual-Ring Interconnect Circuit Hold-Off Timer
DLP-F301 Edit SNCP 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.
Step1 From the View menu, choose Go to Network View.
Step2 Click the Circuits tab.
Step3 Click the SNCP circuit you want to edit, then click Edit.
Step4 In the Edit Circuit window, click the SNCP Selectors tab.
Step5 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.
Step6 Click Apply, then close the Edit Circuit window by choosing Close from the File menu.
Step7 Return to your originating procedure (NTP).
DLP-F302 Change Tunnel Type
Purpose This task changes the amount of time a path selector switch is delayed for
circuits routed on an SNCP 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 SNCP selectors.
