IP Interface
You can configure the information of IPv4 and IPv6 in this section. IPv4 DHCP configurations include:
Enable: check to enable IPv4 DHCP function.  Fallback: specifies the number of seconds for trying to obtain a DHCP lease.  Current Lease: For DHCP interfaces with an active lease, the column shows
the current interface address, as provided by the DHCP server.
IPv4 configurations include: Address: shows the IPv4 address of the interface in dotted decimal notation. If
DHCP is enabled, this field is not used. The field may also be left blank if IPv4 operation on the interface is not desired.
Mask Length: the IPv4 network mask, in number of bits (prefix length). Valid
values are between 0 and 30 bits for a n IPv 4 addr e ss. If D HC P is ena ble d, this field is not used. The field may also be left blank if IPv4 operation on the interface is not desired.
IPv6 configurations include: Address: shows the address of the interface. A IPv6 address is in 128-bit
records represented a s eight fields of up t o four hex adecimal digit s w ith a colon separating each field (:). For example, fe80::21:cff:fe03:4dc7. The symbol :: is a special syntax that can be used as a shorthand way of representing multiple 16-bit groups of contiguous zeros; but it can appear only once. It can also represent a legally valid IPv4 address. For example: 192.1.2.34. The field may be left blank if IPv6 operation on the interface is not desired.
Mask Length: the IPv6 network mask, in number of bits (prefix length). Valid
values are between 1 and 128 bits for a IPv6 address. The field may be left
Input the IP address of the IPv4 network interface.
Note: After you change the IP address and clicking Apply, we suggest
you to login again, and making sure the URL is the latest IP
IP Routes
Delete: Select this option to delete an existing IP route.  Network: The destination IP network or host address of this route. Valid format
is dotted decimal notation or a valid IPv6 notation. A default route can use the value 0.0.0.0 or IPv6 notation.
Mask Length: T he destinatio n IP netw ork or hos t mask, i n number of b it s (pref ix
length). It defines how much of a network address that must match, in order to qualify for this route. Valid values are between 0 and 32 bits respectively 128 for IPv6 routes. Only a default route will have a mask length of 0 (as it will match anything).
Gateway: The IP address of the IP gateway. Valid format is dotted decimal
notation or a valid IPv6 notation. Gateway and Network must be of the same type.
Next Hop VLAN: The VLAN ID (VID) of the specific IPv6 interface associated
with the gateway. The given VID ranges from 1 to 4094 and will be effective only when the corresponding IPv6 interface is valid. If the IPv6 gateway address is link-local, it must specify the next hop VLAN for the gateway. If the IPv6 gateway address is not link-local, system ignores the next hop VLAN for the gateway.

3.1.8 RIP

RIP (Routing Information Protocol) is one of the protocols which may be used by routers to exchange network topology information. It is characterized as an “interior” gateway protocol, and is typically used in small to medium-sized networks. A rout er running RIP sends the contents of i ts routing table to each of it s a dja cent routers every 30 seconds. When a route is removed from the routing table it is flagged as unusable by the receiving routers after 180 seconds, and removed from their tables after an additional 120 seconds. You can choose to enable or disable RIP in the section.

3.1.9 VRRP

A VRRP (Virtual Router Redundancy Protocol) is a computer networking protocol aimed to eliminate the single point of failure by automatically assigning available IP routers to participating hosts. Using a virtual router ID (VRID) address and virtual router IP (VRIP) address to repres ent itself, a virtual router consists of two or more physical routers, including one master router and one or more backup routers. All routers in the virtual router group share the same VRID and VRIP. The master router provides primary routing and the backup routers monitor the status of the master router and become active if the master router fails.

3.4 Redundancy

In some network environments, users need to set up redundant loops in the network to provide a backup path for disconnection or a network device breakdown. But if there are many network devices in the network, then each host needs to spend more time and cross many network devices to associate with each other. And sometimes the disconnection happens in a busy network, so the network must recover in a short time. Setting up redundancy on your network helps protect critical links against failure, protects against network loops, and keeps network downtime at a minimum. For example, if the Delta switch is used as a key communication component of a production line, several minutes of downtime may cause a big loss in production and revenue.

3.5 Virtual LANs

Virtual LAN (VLAN) is a logical group network. VLANs electronically separate interfaces on the same switch into different broadcast domains so that broadcast packets are not sent to all the interfaces on a single switch. VLAN allows the switch manager to isolate network traffic so that only members of the VLAN can receive traffic from the same VLAN members. VLAN also allows a user to access the network from a different place or switch. So VLAN provide security and flexibility.
For example: Configure department A, B, C to VLAN 1, 2, 3. Users can only access the resource which belongs to their department, so the resource in their department can be protected. And they can access the resource in a different floor, even though in a different place. So they do not need to st ay in a fixed place to access the resource which be lon gs to t heir department.

3.7 Traffic Prioritization

The traffic priorit ization allows you to make sure that the time-sensitive and system-critical dat a can be tran sferr ed w ith the minimal delay. It uses four queues that are present in UI from the high prior it y to the low priority.
A Delta switch supports the DSCP trust mode, the 802.1p trust mode, the queue scheduling (Support Weighted Round Robin and Strict-Priority) and 4 level priority queues. The traffic prioritization depends on 2 methods:
IEEE 802.1P: a layer 2 marking scheme.  Differentiated Services (DiffServ): a layer 3 marking scheme.

3.7.1 Storm Control

A traffic storm occurs when incoming packets flood the LAN, which causes the decreasing of the network performance.
The storm control can prevent flood ing p acket s from affecting the network performance. A Delta L ay er 3 switch allows you
to configure both storm control for each interface and rate limiting of each interface for incoming and outgoing traffic.

3.8 Multicast

Multicast IP traffic is traffic that is assigned to a host group. Host groups are identified by class D IP addresses, which range from 224.0.0.0 to 239.255.255.255. A multicast IP packet is only sent by one host to multiple hosts. Only those hosts that belong to a specific mult ica st group will receiv e t he mu lti cas t. The Internet Group Management Protocol (IGMP) snooping enables the switch to forward multicast traffic intelligently to only the interface that requests the multicast traffic. So the network resource is not wasted too much.
If there is a network without the multicast filtering, and a host needs to send data to many hosts, then it needs to produce several copies in the network. It wastes too much network bandwidth. If there is a network with the multicast filtering, then it reduces the load of resources (ex. a server) and makes the network bandwidth efficient. The figures below show the difference between the network without Multicast Filtering and the network with Multicast Filtering.
