Chapter 6 Circuits and Tunnels

Creating VC Low-Order Path Tunnels for Port Grouping

Figure 6-5 Creating an automatically-routed circuit (low-order path tunnel)

Step 4

(SNCP protection only) Set the SNCP path selector defaults:

• Revertive—Check this box if you want traffic to revert to the working path when the conditions that

diverted the traffic to the protect path are repaired. If Revertive is not chosen, traffic remains on the

protect path after the switch.

• Reversion time—If Revertive is checked, set the reversion time. This is the amount of time that will

elapse before the traffic reverts to the working path. Traffic can revert when conditions causing the

switch are cleared (the default reversion time is 5 minutes).

• SF threshold—Choose from one E-3, one E-4, or one E-5.

• SD threshold—Choose from one E-5, one E-6, one E-7, one E-8, or one E-9.

• Switch on PDI-P—The checkbox is automatically deselected.

Step 5 Click Next.

Step 6 In the Circuit Source dialog box, set the circuit source.

Options include node, slot, and VC4. The options that display depend on the circuit type and circuit

properties you selected in Step 3 and the cards installed in the node. For Ethergroups, see the “E Series

Circuit Configurations” section on page 9-14 and the “G1000-4 Circuit Configurations” section on

page 9-30.

Step 7 Click Next.

Step 8 In the Circuit Destination dialog box, enter the appropriate information for the circuit destination.

Step 9 Click Next. Under Circuit Routing Preferences (Figure 6-6 on page 6-13), Route Automatically is

selected.

Step 10 If you want the circuit routed on a protected path, select Fully Protected Path and choose one of the

following path diversity options. Otherwise, continue with Step 11.
