CLI Cookbook: Removing IP Addresses from a Network Interface

This topic describes how to unset an IP address on a network interface.

Removing a Single 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.

   guild.dcol1> network interface
   guild.dcol1 network interface> list
   NAME    MACADDRESS         MTU
   ens160  02:dc:02:00:7f:06  1500
   guild.dcol1 network interface> select ens160
   guild.dcol1 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 updatecommand and unset address.

   guild.dcol1 network interface 'ens160'> update
   guild.dcol1 network interface 'ens160' update *> unset addresses
   guild.dcol1 network interface 'ens160' update *> get
       type: NetworkInterface
       name: ens160
       addresses: (unset) (*)
       mtu: 1500

3. Commit the operation.

   guild.dcol1 network interface 'ens160' update *> commit
   guild.dcol1 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 Multiple IP Addresses

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

   guild.dcol1> network interface
   guild.dcol1 network interface> list
   NAME    MACADDRESS         MTU
   ens160  02:dc:02:00:7f:06  1500
   guild.dcol1 network interface> select ens160
   guild.dcol1 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
   guild.dcol1 network interface 'ens160'> update

2. Run the updatecommand and unset address.

   guild.dcol1 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
   guild.dcol1 network interface 'ens160' update *> unset addresses.0
   guild.dcol1 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.

   guild.dcol1 network interface 'ens160' update *> commit
   guild.dcol1 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
