Use the INTERFACE statement to specify a static virtual interface.
You can define multiple virtual IPv4 addresses on one TCP/IP image by specifying multiple VIRTUAL INTERFACE statements.
Syntax
>>-INTERFace intf_name------------------------------------------> >--+-DEFINE--VIRTUAL--| Interface Definition |-+--------------->< '---DELEte----------------------------------' Interface Definition |--IPADDR - ipv4_address----------------------------------------|
Parameters
- intf_name
- The name of the interface. The maximum length is 16 characters.
- DEFINE
- Specifies that this definition is to be added to the list of defined interfaces.
- DELETE
- Specifies that this definition is to be deleted from the list of defined interfaces. The intf_name must be the name of an interface previously defined by an INTERFACE statement. INTERFACE DELETE deletes all home IP addresses for the interface.
- VIRTUAL
- Indicates that the interface is not associated with real hardware and is used for fault tolerance support.
- IPADDR ipv4_address
- This parameter is required and must be one IPv4 address specified in dotted decimal form.
Steps for modifying
See Summary of INTERFACE statements for modification information.

- The TCP/IP stack does not maintain interface counters for VIRTUAL interfaces.
- A VIRTUAL interface name cannot be coded in the BEGINROUTES block.
