Module Configuration

The Module should be uploaded into NFO and enabled. In NetFlow Optimizer Home page click on upload button, and select the package to upload (e.g. v2p_network_visibility-2.6.0.1.1-linux-x86_64.zip).

Once uploaded, click on to enable the Module. You don’t have to restart the server – the Module is operational when enabled.

This Module is highly configurable. Click on V2P Network Visibility Module and you will be presented with the following screen.

Configure your vCenter integration by setting up List of cVenter Virtual Machines Data set. All other parameters are optional. Contact NetFlow Logic support before changing any parameters.

Table 4 - Configuration Parameters

Parameter Name

Description

Default sampler rate

A default sampling rate for sampled flows for which exact sampling information is missing. min = 1, max = 100000, default = 1

Network path information reporting interval, sec

This parameter controls Network path periodic updates. Once discovered path is detected and reported, if it is still active, it will be reported again after this period of time. min = 120 sec, max = 14400 sec, default = 300 sec

Output method: 0 - syslog (push), 1 - REST (pull), 2 - both

This parameter controls how you want the output from this Package to be available. values {0, 1, 2}, default = 0

Inactivity timeout for network paths, sec

This parameter controls inactivity period after which path is no longer reported. min = 60 sec, max = 14400 sec, default = 300 sec

N - number of reported tunnels

Number of reported tunnels. min = 1, max = 100000, default = 50

Network Health Analytics and Reporter

This parameter controls network health score reporting interval in seconds. Network health is reported in syslogs with nfc_id = 20180 and nfc_id = 20181. min = 5, max = 600, default = 23

Network Paths Analytics

This parameter controls the internal interval used in detecting paths between pairs of peers. min = 5, max = 600, default = 37

Network Paths Reporter

This parameter controls network path reporting interval in seconds. Network path is reported in syslogs with nfc_id = 20183. min = 5, max = 600, default = 203

VM - VM Hosts Adjacency

This parameter controls VM - VM Host-ToR Adjacency reporting interval in seconds. This information is reported in syslogs with nfc_id = 20184. min = 5, max = 600, default = 41

ToR Switches Discovery

This parameter controls the internal interval in seconds used in discovering ToR switches. min = 5, max = 600, default = 29

VM Conversations

This parameter controls VM Conversations reporting interval in seconds. This information is reported in syslogs with nfc_id = 20186. min = 15, max = 600, default = 30

Top Tunnels

This parameter controls Top Tunnels reporting interval in seconds. This information is reported in syslogs with nfc_id = 20187. min = 15, max = 600, default = 30

List of vCenter Virtual Machines

This watch list is populated by External Data Feeder for NFO Agent by connecting to one or several vCenters

List of ToRs management addresses

This watch list helps the Module to determine which devices are Top of the Rack Switches. ToRs detected automatically if list is empty

List of subnets for broadcast filtering

This watch list helps the Module to filter broadcast IP addresses. Broadcast addresses filtered if belong to the subnet from this list

Click on List of vCenter Virtual Machines to setup integration with vCenters, vShield, and NSX as shown below.

Once connected to vCenter, you can enable NetFlow export from VDSs, specifying it at VDS Portgroup level.

You don’t need to restart NetFlow Optimizer or enable/disable the Module in order for the new parameters to take effect.

Next time

Next scheduled update time based on the schedule setting below.

Schedule/Expression

Unix cron expression

vCenter server name

IP address or name of vCenter server

vCenter user name/password

vCenter login credentials

Log level

Leave blank or set to DEBUG for troubleshooting

Data Records

This watchlist is a csv list in the following format: VDS IPv4 address, VM IPv4 address, VM host , VTEP IPv4 address, VM name, VM UUID
