+ Root Guard protects root bridge from malicious attack or configuration mistakes
Layer 2 Switching
+ Supports up to 512 VLANs simultaneously (out of 4K VLAN IDs).
Quality of Service
+ Supports L2/L3 granular CoS with 4 priority queues per port.
+ Rate limiting confines the traffic flow accurately according to the preset value.
Manageability
+ Supports Telnet, SNMP v1/v2c/v3, RMON and web access.
+ Port Mirroring enables monitoring selected ingress/egress traffic.

4.1.5 System IP
Each device in the network possesses a unique IP Address. You can log on to the Web
management page to operate the switch using this IP Address. The switch supports three modes
to obtain an IP address: Static IP, DHCP and BOOTP. The IP address obtained using a new mode
will replace the original IP address. On this page you can configure the system IP of the switch.
Choose the menu System→System Info→System IP to load the following page.

The following entries are displayed on this screen:
IP Config
14
Management VLAN:
Enter the ID of management VLAN, the only VLAN through which
you can get access to the switch. By default VLAN1 owning all the
ports is the Management VLAN and you can access the switch via
any port on the switch. However, if another VLAN is created and
set to be the Management VLAN, you may have to reconnect the
management station to a port that is a member of the
Management VLAN.
IP Address:
Enter the system IP of the switch. The default system IP is
192.168.1.1 and you can change it appropriate to your needs.
Subnet Mask:
Enter the subnet mask of the switch.
Default Gateway:
Enter the default gateway of the switch.
Note:
1. Changing the IP address to a different IP segment will interrupt the network communication,
so please keep the new IP address in the same IP segment with the local network.
2. The switch only possesses an IP address. The IP address configured will replace the original
IP address.
3. If the switch gets the IP address from DHCP server, you can see the configuration of the
switch in the DHCP server; if DHCP option is selected but no DHCP server exists in the
network, a few minutes later, the switch will restore the setting to the default.
4. If DHCP or BOOTP option is selected, the switch will get network parameters dynamically
from the Internet, which means that its IP address, subnet mask and default gateway can not
be configured.
5. By default, the IP address is 192.168.1.1.
4.2 User Management

Switching module is used to configure the basic functions of the switch, including four submenus:
Port, LAG, Traffic Monitor and MAC Address.
5.1 Port
The Port function, allowing you to configure the basic features for the port, is implemented on the
Port Config, Port Mirror, Port Security and Port Isolation pages.
5.1.1 Port Config
On this page, you can configure the basic parameters for the ports. When the port is disabled, the
packets on the port will be discarded. Disabling the port which is vacant for a long time can reduce
the power consumption effectively. And you can enable the port when it is in need.
The parameters will affect the working mode of the port, please set the parameters appropriate to
your needs.

Speed and Duplex mode will be determined by
auto-negotiation. For the SFP port, this switch does not support
auto-negotiation.
Flow Control:

Flow Control is enabled, the switch can synchronize the speed
with its peer to avoid the packet loss caused by congestion.
LAG:
