Enable Performance Monitoring

Check the check box to enable performance monitoring.

Ensure that you do not clear interface counters from the Command Line Interface of the switches. Clearing interface counters can cause the Performance Monitor to display incorrect data for traffic utilization. If you must clear the counters and the switch has both clear counters and clear counters snmp commands (not all switches have the clear counters snmp command), ensure that you run both the main and the SNMP commands simultaneously. For example, you must run the clear counters interface ethernet slot/port command followed by the clear counters interface ethernet slot/port snmp command. This can lead to a one time spike.

Update the fields as needed. The values shown in your screen are automatically generated. If you want to update the IP address ranges or the VRF/Network VLAN ranges, ensure that it does not overlap with other ranges. You should only update one range of values at a time. If you want to update more than one range of values, do it in separate instances. For example, if you want to update Layer 2 and Layer 3 ranges, you should do the following:

After you enable bootstrap, you can enable the DHCP server for automatic IP address assignment using one of the following methods:

Enable Local DHCP Server

Select this check box to initiate enabling of automatic IP address assignment through the local DHCP server. When you select this check box, the DHCP Scope Start Address and DHCP Scope End Address fields become editable.

If you do not select this check box, Nexus Dashboard Fabric Controller uses the remote or external DHCP server for automatic IP address assignment.

DHCP Scope Start Address, DHCP Scope End Address, Switch Management Default Gateway, Switch Management Subnet Prefix

For example: 10.6.0.2, 10.6.0.9, 10.6.0.1, 24

Enable AAA Config

Select this check box to include AAA configurations from the Manageability tab as part of the device start-up config post bootstrap.

Bootstrap Freeform Config

(Optional) Enter additional commands as needed. For example, if you require some additional configurations to be pushed to the device and be available post device bootstrap, they can be captured in this field, to save the desired intent. After the devices boot up, they will contain the configuration defined in the Bootstrap Freeform Config field.

Copy-paste the running-config to a freeform config field with correct indentation, as seen in the running configuration on the NX-OS switches. The freeform config must match the running config. For more information, see Enabling Freeform Configurations on Fabric Switches.

Hourly Fabric Backup

Select the check box to enable an hourly backup of fabric configurations and the intent. The hourly backups are triggered during the first 10 minutes of the hour.

Scheduled Fabric Backup

Check the check box to enable a daily backup. This backup tracks changes in running configurations on the fabric devices that are not tracked by configuration compliance.

Scheduled Time

Specify the scheduled backup time in a 24-hour format. This field is enabled if you check the Scheduled Fabric Backup check box.

Select both the check boxes to enable both back up processes. The backup process is initiated after you click Save.

The scheduled backups are triggered exactly at the time you specify with a delay of up to two minutes. The scheduled backups are triggered regardless of the configuration deployment status.

The number of fabric backups that will be retained on NDFC is decided by the Settings > Server Settings > LAN Fabric > Maximum Backups per Fabric.

The number of archived files that can be retained is set in the # Number of archived files per device to be retained: field in the Server Properties window.

Note: To trigger an immediate backup, do the following:

You can also initiate the fabric backup in the fabric topology window. Click Backup Now in the Actions pane.

Enable Netflow

Check this check box to enable Netflow on Aggregation devices for this fabric. By default, Netflow is disabled. On Enable, NetFlow configuration will be applied to all Aggregation devices that support Netflow.

---

When Netflow is enabled on the fabric, you can choose not to have netflow on a particular switch by having a dummy no_netflow PTI.

---

If netflow is not enabled at the fabric level, an error message is generated when you enable netflow at the interface, network, or VRF level. For information about Netflow support for Cisco NDFC, see the section "Netflow Support" in Understanding LAN Fabrics.
