IP Multinetting

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.

Application Limitation: A multicast router cannot be connected to IP
interfaces that are utilizing the IP Multinetting function.
NOTE: Only the primary IP interface will support the BOOTP relay agent.
