Install Juniper Unified PON Controller on NFX250-S2

Overview

This installation example can be used to install an Ubuntu KVM qcow2 image for the MicroClimate Management System (MCMS ) passive optical network (PON) Controller software to run as a Virtual Network Function (VNF) on the NFX250-S2 Network Services Platform and provision the NFX250-S2 for the VNF.

Note:

The steps to create the Ubuntu KVM qcow2 image for the MCMS PON Controller software is beyond the scope of this document.

Deployment Model

The PON Controller software runs as a VNF (as an Ubuntu VM) on the NFX250-S2 device and utilizes the NFX250’s external faceplate Gigabit Ethernet switch ports. The NFX250-S2 switch ports provide the Layer 2 and Layer 3 connection points to the ACX router and MCMS PON Manager Database, respectfully.

Figure depicts the field deployment model for this installation example.

Note:

The ACX line of routers supported in this deployment model is the ACX5448 Universal Metro Router.

The Layer 2 control plane connections to the ACX router can use any of the NFX250-S2 device’s top four Ethernet switch ports. For example, ge-0/0/0, ge-0/0/2, ge-0/0/4, or ge-0/0/6.

The Layer 3 control plane connection to the MCMS database can use any one of the NFX250-S2 device’s bottom four Ethernet switch ports. For example, ge-0/0/1, ge-0/0/3, ge-0/0/5, or ge-0/0/7.

Note:

Other ports on the NFX250-S2 device and port configurations may be valid but are beyond the scope of this document.

Figure depicts an example of the internal service connection mapping on the NFX250-S2 device for this PON Controller VNF.

The PON Controller VNF’s two Ethernet control plane connections are mapped from the PON Controller VNF through the NFX250’s OVS bridge structure to the external Gigabit Ethernet faceplate switch ports using internal VLANs. For Junos VLAN configuration, see Example: Configure NFX250-S2 as a Compute Server to Support Virtual Network Functions.

Note:

Other possible VLAN configurations are beyond the scope of this document.
