Ip Commands (Including Ip Multinetting) - D-Link xstack DGS-3612G Instruction 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.
Command
create ipif
config ipif
enable ipif
disable ipif

Each command is listed, in detail, in the following sections.

Parameters
<ipif_name 12> <network_address> <vlan_name 32> {secondary | state [enable | disable]}
<ipif_name 12> [{ipaddress <network_address> | vlan <vlan_name 32> | state [enable |

{<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, (10.1.2.3/8). (This parameter
may also appear as <ip_addr/netmask>).
<vlan_name 32> − The name of the VLAN that will be associated with the above
IP interface.
secondary – Enter this parameter if this configured IP interface is to be a
secondary IP interface of the VLAN previously specified. secondary interfaces
can only be configured if a primary interface is first configured.
state [enable | disable] − Allows the user to enable or disable the IP interface.
Only administrator-level users can issue this command.
