Chapter 6 Create Circuits and VT Tunnels
NTP-A191 Create an E-Series EtherSwitch Circuit (Multicard or Single-Card Mode)
Step 8 In the Create Circuits dialog box, complete the following fields:
• Circuit Type—Choose STS.
• Number of Circuits—Leave the default unchanged (1).
• 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 an Ethernet multicard circuit are STS-1,
STS-3c, and STS6c. Valid circuit sizes for an Ethernet single-card circuit are STS-1, STS-3c,
STS6c, and STS12c.
• Bidirectional—Leave the default unchanged (checked).
• Create cross-connects only (TL1-like)—Uncheck this box; it does not apply to Ethernet circuits.
• State—Choose IS (in service). Ethergroup circuits are stateless and always in service.
• Apply to drop ports—Uncheck this box; states cannot be applied to E-Series Ethernet card ports.
• Protected Drops—Leave the default unchanged (unchecked).
Step 11 If the circuit will be routed on a path protection, complete the “DLP-A218 Provision Path Protection
Selectors” task on page 19-12.
Caution Layer 1 SONET protection does not extend to multicard EtherSwitch circuits on path protection.
Caution A TCC2/TCC2P card reset disrupts single-card and multicard EtherSwitch circuits for 45 seconds to two
minutes. During this time, a spanning tree topology is created by the newly activated TCC2/TCC2P card.
Step 12 Click Next.
Step 13 Provision the circuit source:
a. From the Node drop-down list, choose one of the EtherSwitch circuit endpoint nodes. (Either end
node can be the EtherSwitch circuit source.)
b. From the Slot drop-down list, choose one of the following:
• If you are building a multicard EtherSwitch circuit, choose Ethergroup.
• If you are building a single-card EtherSwitch circuit, choose the Ethernet card where you
enabled the single-card EtherSwitch.
Step 14 Click Next.
Step 15 Provision the circuit destination:
a. From the Node drop-down list, choose the second EtherSwitch circuit endpoint node.
b. From the Slot drop-down list, choose one of the following:
• If you are building a multicard EtherSwitch circuit, choose Ethergroup.
• If you are building a single-card EtherSwitch circuit, choose the Ethernet card where you
enabled the single-card EtherSwitch.
