Step 8
Step 9 Complete the
VCAT circuit that you are creating.
In the Circuit Routing Preferences area, uncheck Route Automatically.
Step 10
Step 11 Choose one of the following routing types:
• Common Routing—Routes the members on the same fiber.
• Split Routing—Allows the individual members to be routed on different fibers or each member to
have different routing constraints. Split routing is required when creating circuits over a path
protection configuration.
If you want to set preferences for individual members, complete the following in the Member
Step 12
Preferences area. To set identical preferences for all members, skip this step and continue with
Number—Choose a number from the drop-down list to identify the member.
•
Name—Type a unique name to identify the member. The name can be alphanumeric and up to
•
48 characters (including spaces). If you leave the field blank, CTC assigns a default name to the
circuit.
Protection—Choose the member protection type:

While deleting SW-LCAS circuit members change the administrative state of the members
to Locked,disabled. This is applicable to circuits created on CE-Series and ML-Series cards.
LCAS—Sets the VCAT circuit to use LCAS. With LCAS, you can add or delete members
without interrupting the operation of noninvolved members, and if a member fails, LCAS
temporarily removes the failed member from the VCAT circuit. The remaining members carry
the traffic until the failure clears.
Cisco recommends using LCAS for CE-100T-8 and ML-100T-8 cards that do not need to
interoperate with the ONS 15454 ML-Series cards.
For CE-MR-6 card, before you create a VCAT circuit in the LCAS protection mode, it is
recommended that you move all members of the VCAT circuit being created to
Locked,OutOfGroup service state and then move them to Unlocked state.
While deleting HW-LCAS circuit members change the administrative state of the members
to Locked, OutOfGroup. This is applicable to circuits created on CE-Series and ML-Series
cards.

Fully Protected—Routes the circuit on a protected path.
Unprotected—Creates an unprotected circuit.
PCA—(Future use) Routes the member on a MS-SPRing protection channel.
Although ONS 15310-MAs do not support MS-SPRing, you can route an LCAS VCAT

circuit over a MS-SPRing network of ONS 15600s or ONS 15454s.
