Getting Started

This chapter describes the software and hardware requirements and summarizes the steps for deploying the DANZ Monitoring Fabric (DMF) Controller.

 

DMF Installation Prerequisites

Follow the prerequisite steps below:

Table 1. DANZ Monitoring Fabric (DMF) Prerequisites
Task Description Comments
1. Connect the management port of the DMF switches to the management network switch.  
2. Connect the DMF switch console port to the console server. The default baud rate is 9600 for Arista Networks switches. The default baud rate is 115200 for ONIE-enabled switches.  
3. Connect the DMF Controller, Service Node, Recorder Node, and Analytics Node Ethernet port to the management network switch.  
4. For the DMF Controller, Service Node, Recorder Node, and Analytics Node, connect the iDRAC port to the management network (if possible, to a different subnet). Assign an iDRAC IP and validate the DMF Controller, Service Node, Recorder Node and, Analytics Node iDRAC are reachable. The default password for iDRAC should be at the bottom of the Service Tag.  
5. Connect the DMF Service Node and Recorder Node data ports to the DMF switch per customer-designed topology. Refer to Overview for Service Node data ports and Overview for Recorder Node data port.  
6. On the management network switch, ensure that spanning-tree mode edge or spanning-tree mode portfast is enabled for all the ports to which the DMF appliances and switches are connected.  
7. On management network switch ensure that IGMP snooping is disabled.  
8 On the management network switch ensure IPv6 communication in the L2 domain.  
9. Verify reachability to NTP, DNS, and default gateway IP address for the management network.  
10. For L3 deployment (where Controller, DMF switches, DMF Service Node, or DMF Recorder Node are in different subnets), ensure the correct ports on the firewall are open. Refer to Management Plane Security (Protocol Access Required for the DMF Controller) for a list of ports on the firewall to open.  

Downloading Software

The Arista Support Portal provides links to software packages and documentation for DANZ Monitoring Fabric (DMF) products.

To download the DMF software or documentation, click the DMF (BMF) / CCF (BCF) tab and expand the DANZ Monitoring Fabric (DMF) - Big Monitoring Fabric (BMF) folder tree.

Download the appropriate release documents from the DMF - BMF Product Documentation folder tree.

To download software, expand the DMF - BMF Software Downloads folder tree and locate the required software from either DMF - BMF Latest Recommended Release, DMF - BMF Prior Recommended Release, or DMF - BMF All Releases folder trees.
