The following section will aid the user in configuring security functions for the Switch. The Switch includes various functions for
IP Interface Settings, MD5 Key Settings, Route Redistribution Settings, Static/Default Route Settings, Route Preference Settings,
Static ARP Settings, RIP, OSPF, DCHP/BOOTP Relay, DNS Relay, VRRP, and IP Multicast Routing Protocol all discussed in
detail in the following section.

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.

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.

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.
