Removing IP addresses from a network interface

This topic describes how to remove one or more IP addresses from a network interface.

Removing all IP addresses

Procedure

1. Log in to the Delphix Engine as the sysadmin user and switch to the network interface context. Then use the list command to view the available network interfaces, and select the interface.

   CODE

   delphix> network interface
   delphix network interface> list
   NAME    MACADDRESS         MTU
   ens160  02:dc:02:00:7f:06  1500
   delphix network interface> select ens160
   delphix network interface 'ens160'> get
       type: NetworkInterface
       name: ens160
       addresses:
           0:
               type: InterfaceAddress
               address: 10.43.70.135/16
               addressType: DHCP
               enableSSH: true
               sessionInUse: false
               state: OK
       device: ens160
       macAddress: 02:dc:02:00:7f:06
       mtu: 1500
       mtuRange: 68-9000
       reference: NETWORK_INTERFACE-ens160
       state: OK

2. Run the update command and unset the addresses property to remove all addresses. Note that in this example, we only had one address to remove, but this procedure removes all addresses even if more than one were configured.

   CODE

   delphix network interface 'ens160'> update
   delphix network interface 'ens160' update *> unset addresses
   delphix network interface 'ens160' update *> get
       type: NetworkInterface
       name: ens160
       addresses: (unset) (*)
       mtu: 1500

3. Commit the operation.

   CODE

   delphix network interface 'ens160' update *> commit
   delphix network interface 'ens160'> get
       type: NetworkInterface
       name: ens160
       addresses: (empty)
       device: ens160
       macAddress: 02:dc:02:00:7f:06
       mtu: 1500
       mtuRange: 68-9000
       reference: NETWORK_INTERFACE-ens160
       state: OK

Removing a specific IP address

1. Log in to the Delphix Engine as the sysadmin user and switch to the network interface context. Then use the list command to view the available network interfaces, and select the interface. Note that in this example, there are two addresses, a static address, and a DHCP address.

   CODE

   delphix> network interface
   delphix network interface> list
   NAME    MACADDRESS         MTU
   ens160  02:dc:02:00:7f:06  1500
   delphix network interface> select ens160
   delphix network interface 'ens160'> get
       type: NetworkInterface
       name: ens160
       addresses:
           0:
               type: InterfaceAddress
               address: 10.11.12.13/24
               addressType: STATIC
               enableSSH: true
               sessionInUse: false
               state: OK
           1:
               type: InterfaceAddress
               address: 10.43.70.135/16
               addressType: DHCP
               enableSSH: true
               sessionInUse: false
               state: OK
       device: ens160
       macAddress: 02:dc:02:00:7f:06
       mtu: 1500
       mtuRange: 68-9000
       reference: NETWORK_INTERFACE-ens160
       state: OK

2. Run the update command and unset one of the addresses. In this example, only the static address is removed, retaining the DHCP address.

   CODE

   delphix network interface 'ens160'> update
   delphix network interface 'ens160' update *> get
       type: NetworkInterface
       name: ens160
       addresses:
           0:
               type: InterfaceAddress
               address: 10.11.12.13/24
               addressType: STATIC
               enableSSH: true
           1:
               type: InterfaceAddress
               address: 10.43.70.135/16
               addressType: DHCP
               enableSSH: true
       mtu: 1500
   delphix network interface 'ens160' update *> unset addresses.0
   delphix network interface 'ens160' update *> get
       type: NetworkInterface
       name: ens160
       addresses:
           0:
               type: InterfaceAddress (*)
               address: 10.43.70.135/16 (*)
               addressType: DHCP (*)
               enableSSH: true (*)
       mtu: 1500

3. Commit the operation.

   CODE

   delphix network interface 'ens160' update *> commit
   delphix network interface 'ens160'> get
       type: NetworkInterface
       name: ens160
       addresses:
           0:
               type: InterfaceAddress
               address: 10.43.70.135/16
               addressType: DHCP
               enableSSH: true
               sessionInUse: false
               state: OK
       device: ens160
       macAddress: 02:dc:02:00:7f:06
       mtu: 1500
       mtuRange: 68-9000
       reference: NETWORK_INTERFACE-ens160
       state: OK
