DLP- D361 Create a DCC Tunnel
Note Cisco recommends a maximum of 84 DCC tunnel connections. Terminated RS-DCCs used by the
ONS 15454 SDH cannot be used as DCC tunnel endpoints, and an RS-DCC that is used as a DCC tunnel
endpoint cannot be terminated. All DCC tunnel connections are bidirectional.
Step 1 In network view, click the Provisioning > Overhead Circuits tabs.
Step 2 Click Create.
Step 3 In the Overhead Circuit Creation dialog box, complete the following in the Circuit Attributes area:
• Name—Type the tunnel name.
• Circuit Type—Choose one:
– DCC Tunnel-D1-D3—Allows you to choose either the RS-DCC (D1-D3) or an MS-DCC
(D4-D6, D7-D9, or D10-D12) as the source or destination endpoints.
– DCC Tunnel-D4-D12—Provisions the full MS-DCC as a tunnel.
Step 4 Click Next.
Step 5 In the Circuit Source area, complete the following:
• Node—Choose the source node.
• Slot—Choose the source slot.
• Port—If displayed, choose the source port.
• Channel—These options appear if you chose DCC Tunnel-D1-D3 as the tunnel type. Choose one of
the following:
– DCC1 (D1-D3)—This is the RS-DCC.
– DCC2 (D4-D6)—This is MS-DCC 1.
– DCC3 (D7-D9)—This is MS-DCC 2.
– DCC4 (D10-D12)—This is MS-DCC 3.
DCC options do not appear if they are used by the ONS 15454 SDH (DCC1) or other tunnels.
Step 6 Click Next.
Step 7 In the Circuit Destination area, complete the following:
• Node—Choose the destination node.
• Slot—Choose the destination slot.
• Port—If displayed, choose the destination port.
• Channel—These options appear if you chose DCC Tunnel-D1-D3 as the tunnel type. Choose one of
the following:
– DCC1 (D1-D3)—This is the RS-DCC.
– DCC2 (D4-D6)—This is MS-DCC 1.
– DCC3 (D7-D9)—This is MS-DCC 2.
– DCC4 (D10-D12)—This is MS-DCC 3.
DCC options do not appear if they are used by the ONS 15454 SDH (DCC1) or other tunnels.
Step 8 Click Finish.
