DLP- F301 Edit SNCP Dual-Ring Interconnect Circuit Hold-Off Timer

DLP-F301 Edit SNCP Dual-Ring Interconnect Circuit Hold-Off Timer

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.
Tools/Equipment	None
Prerequisite Procedures	NTP-F152 Provision SNCP Nodes, page 5-13
	DLP-F181 Log into CTC, page 16-34
Required/As Needed	As needed
Onsite/Remote	Onsite or remote
Security Level	Provisioning or higher

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 SNCP circuit you want to edit, then click Edit.

Step 4 In the Edit Circuit window, click the SNCP 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).
