Configuration
Step 1 Complete the “DLP-D60 Log into CTC” task on page 17-49 at the hub node (the common endpoint). If
you are already logged in, continue with Step 2.
Step 2 If you want to assign a name to the circuit source and destination ports before you create the circuit,
complete the “DLP-D314 Assign a Name to a Port” task on page 20-7. If you want CTC to assign a name
automatically based on circuit type, node name, and sequence number, continue with Step 3.
Step 3 Complete the “DLP-D99 Determine Available VLANs” task on page 17-98 to verify that sufficient
VLAN capacity is available. (You will create a VLAN during each circuit creation task.)
Step 4 Verify that the Ethernet card that will carry the hub-and-spoke circuit is provisioned for Single-card
EtherSwitch Group. See the “DLP-D246 Provision E-Series Ethernet Card Mode” task on page 19-50.
Step 5 Provision and enable the Ethernet ports. See “DLP-D220 Provision E-Series Ethernet Ports” task on
page 19-18.
Step 6 Log into the spoke node and repeat Steps 4 and 5 for the Ethernet card in the other circuit endpoint. (You
only need to verify that the hub node is provisioned for single-card EtherSwitch once.)
Step 7 Click the Circuits tab and click Create.
Step 8 In the Circuit Creation dialog box, complete the following fields:
• Circuit Type—Choose VC_HO_PATH_CIRCUIT.
• Number of Circuits—Leave the default (1) unchanged.
• Auto-ranged—Unavailable.
Step 9 Click Next.
Step 10 Define the circuit attributes:
• Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters
(including spaces). Circuit names should be 44 characters or less if you want the ability to create
monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
• Size—Choose the circuit size. Valid circuit sizes for a single-card EtherSwitch circuit are VC4,
VC4-2c, and VC4-4c.
• Bidirectional—Leave the default unchanged (checked).
• Create cross-connects only (TL1-like)—Check this check box if you want to create one or more
cross-connects to complete a signal path for TL1-generated circuits. If you check this box, low-order
tunnels and Ethergroup sources and destinations are unavailable.
Purpose This procedure creates a hub-and-spoke Ethernet configuration, which is
made up of multiple circuits that share a common endpoint. It does not
apply to E-Series cards in port-mapped mode.
Tools/Equipment E-Series Ethernet cards (E100T-G or E1000-2-G) must be installed at all
Ethernet circuit endpoint nodes.
