Configure management VRF

You can assign only management interfaces to the management VRF instance.

Before you assign the management interface to the management VRF instance, delete all the configured settings, including the IP address, on the management interface.

Enter the ip vrf management command in CONFIGURATION mode. Use Non-Transaction-Based Configuration mode only. Do not use Transaction-Based mode.
Add the management interface using the interface management command in VRF CONFIGURATION mode.

Configure management VRF

OS10(config)# ip vrf management
OS10(conf-vrf)# interface management

You can enable various services in both management or default VRF instances. The services that are supported in the management and default VRF instances are:

Configuration notes

All Dell PowerSwitches except S4200-Series, S5200 Series, and Z9332F-ON:

Before you assign the management port to the management VRF instance, you must remove all configured settings on the management port, including the IP address. Perform this action from the console. Removing the IP address disconnects all existing SSH and Telnet sessions on the switch.

The following example shows removing IP address, configuring management VRF, and then adding IP address:
