network interface modify

Description

Parameters

-vserver <vserver> - Vserver Name

Use this parameter to specify the Vserver on which the LIF to be modified is located.

-lif <lif-name> - Logical Interface Name

Use this parameter to specify the name of the LIF that is to be modified

[-home-node <nodename>] - Home Node

Use this parameter to modify the LIF's home node. The home node is the node to which the LIF returns when the network interface revert command is run on that LIF.

[-home-port {<netport>|<ifgrp>}] - Home Port

Use this parameter to modify the LIF's home port. The home port is the port or interface group to which the LIF returns when the network interface revert command is run on that LIF.

Note: If you change this parameter for a cluster or management LIF, you must reboot the storage system to force the change to take effect.

[-address <IP Address>] - Network Address

Use this parameter to modify the LIF's IP address.

Note: A cluster LIF cannot be on the same subnet as a data or management LIF.

{ [-netmask <IP Address>] - Netmask

Use this parameter to modify the LIF's netmask.

| [-netmask-length <integer>] - Bits in the Netmask

Use this parameter to modify the length (in bits) of the LIF's netmask.

[-subnet-name <subnet name>] - Subnet Name

Use this parameter to allocate the interface address from a subnet. Modifying this parameter will cause a new IP address to be allocated and assigned to the interface.

[-status-admin {up|down}] - Administrative Status

Use this parameter to modify the administrative status of the LIF. The administrative status can differ from the operational status. For example, if you specify the status as up but a network problem prevents the interface from functioning, the operational status remains as down.

[-failover-policy {system-defined|local-only|sfo-partner-only|disabled|broadcast-domain-wide}] - Failover Policy

Use this parameter to modify the failover policy for the LIF.

• system-defined - The system determines appropriate failover targets for the LIF. The default behavior is that failover targets are chosen from the LIF's current hosting node and also from one other non-partner node when possible.
• local-only - The LIF fails over to a port on the local or home node of the LIF.
• sfo-partner-only - The LIF fails over to a port on the home node or SFO partner only.
• broadcast-domain-wide - The LIF fails over to a port in the same broadcast domain as the home port.
• disabled - Failover is disabled for the LIF.

Note: The failover policy for cluster logical interfaces is local-only and cannot be changed. The default failover policy for data logical interfaces is system-defined. This value can be changed.

Note: Logical interfaces for SAN protocols do not support failover. Thus, such interfaces always show this parameter as disabled.

[-firewall-policy <policy>] - Firewall Policy

Use this parameter to set the firewall policy for the LIF. A LIF can use a default firewall policy that corresponds to its role (management, cluster, or data) or a custom firewall policy created by an administrator. When using a custom policy, the interface will fallback on its role's default policy for unspecified services. View existing firewall policies with the "system services firewall policy show" command. Modify existing firewall policies with the "system services firewall policy modify" command.

[-auto-revert {true|false}] - Auto Revert

Use this parameter to modify whether a data LIF is reverted automatically to its home node under certain circumstances. These circumstances would include startup, when the status of the management database changes to either master or secondary, and when the network connection is made. The default setting is false. If you set the value of this parameter to true, the load balancing migration capability of the data LIF is disabled (the -allow-lb-migrate parameter is set to false).

Note: Logical interfaces for SAN traffic do not support auto-revert. Thus, this parameter is always false on such interfaces.

[-dns-zone {<zone-name>|none}] - Fully Qualified DNS Zone Name

Use this parameter to modify the unique, fully qualified domain name of the DNS zone to which this data LIF belongs. You can associate a data LIF with a single DNS zone. All data LIFs included in a zone must be on the same Vserver. If you do not specify a value for this parameter, the data LIF is created with the value none.

[-listen-for-dns-query {true|false}] - DNS Query Listen Enable

Use this parameter to specify if the LIF has to listen for DNS queries. The default value for this parameter is true.

[-allow-lb-migrate {true|false}] - (DEPRECATED)-Load Balancing Migrate Allowed (privilege: advanced)

Note: This parameter has been deprecated and may be removed in a future version of Data ONTAP.

Use this parameter to modify whether or not load balancing migration is enabled for this data LIF. The default value of this parameter is false. If you set the value of this parameter to true, the automatic revert capability of the data LIF is disabled (the -auto-revert parameter is set to false). Also, data LIFs that migrate as a result of load balancing adhere to network interface failover rules.

Note: During times when a LIF is hosting active NFSv4, CIFS, or NRV connections, load balancing based LIF migrations between nodes will be temporarily disabled.

[-lb-weight {load|0..100}] - Load Balanced Weight (privilege: advanced)

Use this parameter to modify the load balancing weight of the data LIF. A valid load balancing weight is any integer between 1 and 100. If you specify the same load balancing weight for all data LIFs in a DNS zone, client requests are uniformly distributed, similar to round-robin DNS. A data LIF with a low load balancing weight is made available for client requests less frequently than one that has a high load balancing weight.

[-failover-group <failover-group>] - Failover Group Name

Use this parameter to modify the name of the failover group to associate with the network interface. Manage failover groups using the network interface failover-groups command. Each broadcast domain has a default failover group which is created by the system automatically and has the same name as the broadcast domain. The failover group associated with the broadcast domain includes all ports in the broadcast domain. A logical interface's failover group is set to the failover group of the home port's broadcast domain by default, but this value can be modified.

Note: Logical interfaces for SAN protocols do not support failover. Thus, this parameter cannot be specified for such interfaces.

[-comment <text>] - Comment

Use this parameter to modify the comment associated with the LIF.

[-force-subnet-association [true]] - Force the LIF's Subnet Association

This command will fail if the IP address falls within the address range of a named subnet. Set this to true to acquire the address from the named subnet and assign the subnet to the LIF.

[-is-dns-update-enabled {true|false}] - Is Dynamic DNS Update Enabled?

If this parameter is set to true, then dynamic DNS update is sent to the DNS server for the particular LIF entry if dynamic DNS updates are enabled for the corresponding Vserver. This field is set to true by default for both IPv4 and IPv6 LIFs. DNS Update is not supported on LIFs not configured with either the NFS or CIFS protocol.
