Ip Commands (Including Ip Multinetting) - D-Link xStack DES-6500 Cli Manual

xStack DES-6500 Modular Layer 3 Chassis Ethernet Switch CLI Manual
IP Multinetting is a function that allows multiple IP interfaces to be assigned to the same VLAN. This is beneficial to
the administrator when the number of IPs on the original interface is insufficient and the network administrator wishes not to
resize the interface. IP Multinetting is capable of assigning another IP interface on the same VLAN without affecting the
original stations or settings of the original interface.
Two types of interfaces are configured for IP multinetting, primary and secondary, and every IP interface must be
classified as one of these. A primary interface refers to the first interface created on a VLAN, with no exceptions. All other
interfaces created will be regarded as secondary only, and can only be created once a primary interface has been configured.
There may be five interfaces per VLAN (one primary, and up to four secondary) and they are, in most cases, independent of
each other. Primary interfaces cannot be deleted if the VLAN contains a secondary interface. Once the user creates multiple
interfaces for a specified VLAN (primary and secondary), that set IP interface cannot be changed to another VLAN.
IP Multinetting is a valuable tool for network administrators requiring a multitude of IP addresses, but configuring the
Switch for IP multinetting may cause troubleshooting and bandwidth problems, and should not be used as a long term solution.
Problems may include:
 The Switch may use extra resources to process packets for multiple IP interfaces.
 The amount of broadcast data, such as RIP update packets and PIM hello packets, will be increased.
The IP interface commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the
following table.

{<ipif_name 12>}
Used to create an IP interface on the Switch.
create ipif <ipif_name 12> <network_address> <vlan_name 32>
{secondary | {state [enabled | disabled]}
This command will create an IP interface.
<ipif_name 12>  The name for the IP interface to be created. The user
may enter an alphanumeric string of up to 12 characters to define the IP
interface.
<network_address>  IP address and netmask of the IP interface to be
created. The address and mask information can be specified using the
traditional format (for example, 10.1.2.3/255.0.0.0) or in CIDR format,
