FEATURE | DESCRIPTION |
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. The following 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. |
|
|
Bandwidth Control | Bandwidth control means defining a maximum allowable |
| bandwidth for incoming and/or |
|
|
Broadcast Storm Control | Broadcast storm control limits the number of broadcast, |
| multicast and destination lookup failure (DLF) packets the |
| Switch receives per second on the ports. |
|
|
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. |
|
|
Two Rate Three Color | Two Rate Three Color Marker (trTCM, defined in RFC 2698) is a |
Marker | type of traffic policing that identifies packets by comparing |
| them to two |
| Rate (CIR) and the Peak Information Rate (PIR). |
|
|
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 allow the Switch to communicate with |
| management stations not reachable via the default gateway. |
|
|
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. |
|
|
STP (Spanning Tree | (M)(R)STP detects and breaks network loops and provides |
Protocol) / RSTP (Rapid | backup links between switches, bridges or routers. It allows a |
STP)/MSTP (Multiple | Switch to interact with other |
Spanning Tree Protocol) | your network to ensure that only one path exists between any |
| two stations on the network. |
|
|
Loop Guard | Use the loop guard feature to protect against network loops on |
| the edge of your network. |
|
|
IP Source Guard | Use IP source guard to filter unauthorized DHCP and ARP |
| packets in your network. |
