Installation Requirements
Before installing Cisco Optical Network Controller, you must install Cisco Crosswork Infrastructure 4.04.1.
The infrastucture requirements for installing Cisco Crosswork are listed below. For complete installation requirements, see the Cisco Crosswork Infrastructure 4.0 and Applications Installation GuideCisco Crosswork Infrastructure 4.1 and Applications Installation Guide.
Data Center Requirements
Cisco Crosswork can be deployed in either a vCenter managed data center or onto Cisco CSP. To aid in the deployment, Cisco has developed a cluster installation tool. This tool works in both environments. However, there are limitations to the tool which are detailed later in this section.

VMware Data Center Requirements
This section explains the data center requirements to install Cisco Crosswork on VMware vCenter.
Note |
The following requirements are mandatory if you are planning to install Cisco Crosswork using the cluster installer. If your vCenter data center does not meet these requirements, then the VMs have to be deployed individually, and connectivity has to be established manually between the VMs. |
-
Hypervisor and vCenter supported:
-
VMware vSphere 6.7 or above
-
VMware vCenter Server 7.0 and ESXi 7.0.
-
VMware vCenter Server 6.7 (Update 3g or later) and ESXi 6.7 (Update 1)
-
-
All the physical host machines must be organized within the same VMware Data Center, and while it is possible to deploy all the cluster nodes on a single physical host (provided it meets the requirements), it is recommended that the nodes be distributed across multiple physical hosts.
-
The networks required for the Crosswork Management and Data networks need to be built and configured in the data centers, and must allow low latency L2 communication.
-
To allow use of VRRP, DVS Port group needs to be set as follows:
Property Value Promiscuous mode
Reject
MAC address changes
Reject
Forged transmits
Accept
-
Ensure the user account you use for accessing vCenter has the following privileges:
-
VM (Provisioning): Clone VM on the VM you are cloning.
-
VM (Provisioning): Customize on the VM or VM folder if you are customizing the guest operating system.
-
VM (Provisioning): Read customization specifications on the root vCenter server if you are customizing the guest operating system.
-
VM (Inventory): Create from the existing VM on the data center or VM folder.
-
VM (Configuration): Add new disk on the data center or VM folder.
-
Resource: Assign VM to resource pool on the destination host, cluster, or resource pool.
-
Datastore: Allocate space on the destination datastore or datastore folder.
-
Network: Assign network to which the VM will be assigned.
-
Profile-driven storage (Query): This permission setting needs to be allowed at the root of the DC tree level.
-
-
We also recommend you to enable vCenter storage control.
CSP Data Center Requirements
This section explains the data center requirements to install Cisco Crosswork on Cisco Cloud Services Platform (CSP).
-
Cisco CSP, Release 2.8.0.276
-
Compatible hardware:
UCSC-C220-M4S, UCSC-C240-M4SX
N1K-1110-X, N1K-1110-S
CSP-2100, CSP-2100-UCSD, CSP-2100-X1, CSP-2100-X2
CSP-5200, CSP-5216, CSP-5228
CSP-5400, CSP-5436, CSP-5444, CSP-5456
-
CSP host or cluster is setup and installed with a minimum of two physical ethernet interfaces - one ethernet connected to the Management network, and the other to the Data network.
VM Host Requirements
This section explains the VM host requirements.
Requirement |
Description |
||
---|---|---|---|
CPU/Memory/Storage Profiles (per VM) |
The data center host platform has to accommodate three VMs of the following minimum configuration: VMware vCenter:
Cisco CSP:
Few things to note:
|
||
Additional Storage |
10 GB (approximately) of storage is required for the Crosswork OVA (in vCenter), OR the Crosswork QCOW2 image on each CSP node (in CSP). |
||
Network Connections |
For production deployments, we recommend that you use dual interfaces, one for the Management network and one for the Data network. For optimal performance, the Management and Data networks should use links configured at a minimum of 10 Gbps. |
||
IP Addresses |
Two IP subnets, one for the Management network and one for Data network, with each allowing a minimum of four assignable IP addresses (IPv4 or IPv6). A Virtual IP (VIP) address is used to access the cluster, and then three IP addresses for each VM in the cluster. If your deployment requires worker nodes, you will need a Management and Data IP address for each worker node.
|
||
NTP Servers |
The IPv4 or IPv6 addresses or host names of the NTP servers you plan to use. If you want to enter multiple NTP servers, separate them with spaces. These should be the same NTP servers you use to synchronize the Crosswork application VM clock, devices, clients, and servers across your network.
|
||
DNS Servers |
The IPv4 or IPv6 addresses of the DNS servers you plan to use. These should be the same DNS servers you use to resolve host names across your network.
|
||
DNS Search Domain |
The search domain you want to use with the DNS servers, for example, cisco.com. You can have only one search domain. |
Important Notes
-
Cisco Crosswork Infrastructure and applications are built to run as a distributed collection of containers managed by Kubernetes. The number of containers varies as applications are added or deleted.
-
Dual stack configuration is not supported in Crosswork Platform Infrastructure. Therefore, all addresses for the environment must be either IPv4 or IPv6.
