Table 71 Firmware Features
FEATURE | DESCRIPTION |
VLAN | A VLAN (Virtual Local Area Network) allows a physical network to be |
| partitioned into multiple logical networks. Devices on a logical network |
| belong to one group. A device can belong to more than one group. With |
| VLAN, a device cannot directly talk to or hear from devices that are not |
| in the same group(s); the traffic must first go through a router. |
|
|
Layer 2 Management | Forward traffic based on the destination MAC address and VLAN group |
| (ID). |
|
|
QoS | Queuing is used to help solve performance degradation when there is |
| network congestion. Two scheduling services are supported: Strict |
| Priority (SP) and Weighted Round Robin (WRR). This allows the switch |
| to maintain separate queues for packets from each individual source or |
| flow and prevent a source from monopolizing the bandwidth. |
|
|
Rate Control | Rate control is a combination of bandwidth management and broadcast |
| storm control. This feature allows you to set limits for incoming and |
| outgoing traffic on the ports. The broadcast storm control feature helps |
| prevent broadcast, multicast or unknown unicast traffic from flooding |
| your network. |
|
|
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. |
|
|
Link Aggregation | Link aggregation (trunking) is the grouping of physical ports into one |
| logical |
| is cheaper to use multiple |
| speed, but more costly, |
|
|
Device Management | Use the web configurator to easily configure the rich range of features on |
| the switch. |
|
|
Firmware Upgrade | Download new firmware (when available) from the ZyXEL web site and |
| use the web configurator to put it on the switch. |
| Note: Only upload firmware for your specific model! |
|
|
Configuration Backup & | Make a copy of the switch’s configuration and put it back on the switch |
Restoration | later if you decide you want to revert back to an earlier configuration. |
|
|
Auto DoS | The Automatic Denial of Service (DoS) attack detection and prevention |
| feature helps protect you from hackers trying to disrupt or shut down |
| your network. |
|
|
Auto VoIP | The Automatic VoIP feature grants the highest priority to VoIP traffic |
| ensuring better sound quality and reliability for end users. |
