FEATURE | DESCRIPTION |
MAC Address Filter | Filter traffic based on the source and/or destination MAC |
| address and VLAN group (ID). |
|
|
DHCP (Dynamic Host | Use this feature to have the Switch assign IP addresses, an IP |
Configuration Protocol) | default gateway and DNS servers to computers on your |
| network. |
|
|
IGMP Snooping | The Switch supports IGMP snooping enabling group multicast |
| traffic to be only forwarded to ports that are members of that |
| group; thus allowing you to significantly reduce multicast traffic |
| passing through your Switch. |
|
|
Differentiated Services | With DiffServ, the Switch marks packets so that they receive |
(DiffServ) | specific |
| devices along the route based on the application types and |
| traffic flow. |
|
|
Classifier and Policy | You can create a policy to define actions to be performed on a |
| traffic flow grouped by a classifier according to specific criteria |
| such as the IP address, port number or protocol type, etc. |
|
|
Queuing | Queuing is used to help solve performance degradation when |
| there is network congestion. Three scheduling services are |
| supported: Strict Priority Queuing (SPQ), Weighted Round |
| Robin (WRR) and Weighted Fair Queuing (WFQ). This allows the |
| Switch to maintain separate queues for packets from each |
| individual source or flow and prevent a source from |
| monopolizing the bandwidth. |
|
|
Port Mirroring | Port mirroring allows you to copy traffic going from one or all |
| ports to another or all ports in order that you can examine the |
| traffic from the mirror port (the port you copy the traffic to) |
| without interference. |
|
|
Static Route | Static routes tell the Switch how to forward IP traffic when you |
| configure the TCP/IP parameters manually. |
|
|
Multicast VLAN | Multicast VLAN Registration (MVR) is designed for applications |
Registration (MVR) | (such as |
| across a network. MVR allows one single multicast VLAN to be |
| shared among different subscriber VLANs on the network. |
| This improves bandwidth utilization by reducing multicast |
| traffic in the subscriber VLANs and simplifies multicast group |
| management. |
|
|
IP Multicast | With IP multicast, the Switch delivers IP packets to a group of |
| hosts on the network - not everybody. In addition, the Switch |
| can send packets to Ethernet devices that are not |
| by untagging (removing the VLAN tags) IP multicast packets. |
|
|
RIP | RIP (Routing Information Protocol) allows a routing device to |
| exchange routing information with other routers. |
|
|
VRRP | Virtual Router Redundancy Protocol (VRRP), defined in RFC |
| 2338, allows you to create redundant backup gateways to |
| ensure that the default gateway of a host is always available. |
