Description

Geographic Redundancy Support for High Availability

 Cisco NCS 2000 Release 25.1.1

The Cisco Optical Site Manager now facilitates geographic redundancy by connecting two NCS 2000 nodes located in different places.

The Geo HA Mode configuration in SVO-LCs ensures that redundancy is maintained if one of the NCS2000 nodes fails.

HA mode can be deployed in three modes:

  • Local HA

  • Geo HA using the UDC channel

  • Geo HA between near-by NCS2000 nodes

The YAML file is updated to include the redundancy mode setting:

redundancy-mode: "GEO_HA".

HA deployment modes

You can deploy HA in the different modes:

  • Local HA

  • Geo HA between adjacent nodes using UDC channel

  • Geo HA between nearby NCS 2000 nodes

Local HA (Local High Availability)

Local HA mode provides high availability by inserting two SVO-LCs into the same NCS2000 node. This setup ensures redundancy within a single node.

In Local HA mode, two SVO-LCs are installed within the same NCS 2000 node. It provides redundancy by using two SVO-LCs in the same NCS 2000 node and ensures high availability by enabling failover to the standby SVO-LC in case of primary SVO-LC failure. Simplifies deployment by keeping all components within a single node.

The connection requirements for each SVO-LC are outlined below:

  • Connect MGMT1 port to the customer Data Communication Network (DCN).

  • Connect two optical fibers, necessitating the insertion of two pluggables into the SVO-LC card's HA1 and HA2 ports.

  • Connect Port 1 to one TNC and peer SVO-LC port 1 connected to the other TNC.

  • (Optional) Connect NCS 2000 ECU EMS connected to customer DCN (in case of multishelf, the ECU of master chassis), in case there is a specific requirement of direct accessibility of the NCS 2000 device.

Geographic high availability

In Geo HA mode, two SVO-LCs are installed in separate NCS 2000 nodes. The high availability network between these SVO-LCs is transported through the User-Defined Channel (UDC) channel. Each SVO-LC runs a Cisco Optical Site Manager Admin Plane, managing its local line card and communicating with its peer on the other SVO-LC. A Cisco Optical Site Manager instance, representing a virtual network element (vNE), runs on both SVO-LCs, with one in Active state and the other in Standby state.

Benefits of geo HA

Geo HA offers several benefits in terms of redundancy and network reliability:

  • Utilizes two SVO-LCs located in separate NCS2000 nodes to provide robust redundancy.

  • Utilizes the UDC channel or the SVO-LC optical pluggables to transmit high-availability data between adjacent nodes, ensuring uninterrupted operations.

  • Facilitates failover to the standby SVO-LC in the event of primary SVO-LC failure, increasing network resilience.

Geo HA using the UDC channel

Geo HA Mode is a configuration that enhances network reliability and availability by placing two SVO-LC cards into two adjacent NCS 2000 nodes. The UDC channel is utilized to transport the high availability network, ensuring continuous service even in the event of failures.

This image shows the Geo HA connection using the UDC channel.

Figure 2. Geo HA connection using the UDC channel

The Geo HA link is implemented using the available NCS 2000 UDC channel, enabling packet processing at the hardware level without impacting the NCS 2000 controller CPU. It supports a single-path UDC HA link with a theoretical bandwidth of 80 Mbps.

It is important to note that connecting one of the optical HA ports to the local ECU UDC port using the electrical ONS-SE-ZE-EL-C pluggable is not possible. This limitation arises from a re-timer connected to the PPM, which only supports a 1G rate, whereas the NCS 2000 UDC port operates at an FE rate. To address this, port 3 is reconfigured as an electrical HA port and will properly negotiate the FE speed.

The UDC must be configured through CTC, as the Cisco Optical Site Manager does not support this functionality. The UDC is set on the Transponder Node Controller (TNC) pluggable associated with the Optical Supervisory Channel (OSC) connected to the side facing the adjacent node. The same configuration is applied to the corresponding TNC pluggable on the adjacent NCS 2000 node.

Each SVO-LC must be connected as below:

  • Connect MGMT1 port to the customer Data Communication Network (DCN).

  • Connect port 3 to the NCS 2000 ECU UDC/VoIP.

  • Connect port 1 to the NCS 2000 ECU EMS or the same switch (same VLAN) where NCS 2000 ECU EMS is connected.

  • (Optional) NCS 2000 ECU EMS may connect directly to the customer DCN for multishelf setups, offering direct accessibility to the NCS2000 device if needed.

Geo HA between nearby NCS 2000 nodes

In Geo HA mode involving nearby NCS 2000 nodes, the two SVO-LCs are installed in separate NCS 2000 nodes, likely situated within the same building or close enough to allow direct interconnection of the two SVO-LCs through HA optical pluggables.

This image shows Geo HA between nearby NCS 2000 nodes.

Network YAML configuration file

The network YAML configuration file includes essential network details needed to set up the SVO-LC interfaces and the Cisco Optical Site Manager application network infrastructure.

The redundancy-mode must be set to "GEO_HA" for initiating Geo high availability.

Each SVO-LC has an individual network YAML file for installation. When deploying two SVO-LCs for high availability, the only difference between the two files should be the value of the server-name field.

Here an example of IPv4 Network YAML configuration file for Geo HA configuration.


server-name: "Server-A"
mgmt-address-family: "IPv4"
ospf-area-id: "0.0.0.0"
redundancy-mode: “GEO_HA”

    ipv4:
      ip: "10.0.123.0"
      prefix: 22
      gateway: "10.0.123.1"
      host-nic: "10.0.123.2"

      prefix: 24
      gateway: "10.0.123.1"
      host-nic: "10.0.123.2"

      ip: "10.1.123.123"
      prefix: 22
      gateway: "10.1.123.1"
      host-nic: "10.1.123.2"

Prepare the Network Configuration

Use this task to prepare the network configuration for the SVO card model.

Procedure

Step 1

Create a configuration file (network.yml) for each server with the networking configuration data. This file is uploaded during the installation.

Step 2

Cable and configure the related network interfaces (physical or virtual).

Both the configuration files are identical and contain the data for both the servers in HA. The only difference is the server-name attribute that contains the name of the server to which the file is applied.
