Editing the MGMT Interface

This article explains how to edit the configurable parameters of the management interface and establish initial network connectivity.

To add a new non-management interface, see Adding an Interface.

For more complex interface operations, such as defining static routes, see the Skylight Appliance Monitor Command Reference.

Creating two separate interfaces for IPv6 and IPv4 is a solution for this case, both allocated on the same hypervisor interface.

Procedure Requirements

A. A workstation (Windows computer or other computer with a network interface) that has an SSH client application installed (PuTTY or a similar application).

B. The IP address, subnet (expressed as a CIDR value) and default gateway address (optional) that will be assigned to the interface.

C. This procedure must be executed as the visionems user. To execute this procedure, you must know the account credentials.

D. We recommend that you avoid changing the interface used to access the console. If you do change the interface, you will have to reconnect to the console after you have finished editing the interface.

Procedure Steps

To edit the management interface (eth0)

1. Log in to the appliance console as the visionems user.

2. If you are editing the management interface of the Skylight orchestrator, enter the following commands to stop the Skylight orchestrator application server and data store server:
   service stop app_server
   service stop mysql
   If they were already stopped, an error message will be displayed. You can continue this procedure.

3. View the list of interfaces currently defined by entering at the Skylight prompt:
   interface show

4. Check if the management interface has already been defined.

5. To edit the management interface (eth0), enter the following command:
   interface edit eth0* address x.x.x.x/CIDRvalue gateway y.y.y.y
   where:
   eth0* the asterisk (*) indicates that this will be the primary interface of the appliance.
   y.y.y.y is the IP address of the gateway for the subnet.

• The gateway parameter is optional and can be omitted.
• Only one interface on the appliance can be configured as a gateway.
• To unconfigure a gateway, use the value 0.0.0.0

6. If you just edited the management interface of the only Skylight orchestrator appliance (in a single appliance deployment), restart the Skylight orchestrator data store server and its application server by entering these commands:
   service start mysql
   service start app_server

7. Redisplay the list of interfaces and confirm that your changes have been applied:
   interface show
   The output displayed should be similar to the following:

Interface name    State     DHCP   IP address             Gateway              Info
----------------- -------- -------- ------------------- ---------------------- --------------
eth0*             Enabled  Disabled 10.235.0.8/16        10.235.0.1            primary
