Mode: There are three modes, by default it’s “disabled”
Disabled: Allow all IP network addresses to login to this switch and to manage it.
Static: Only configured IP network addresses (IP with IP mask) are allowed to login to this switch and to
manage it. Only the the received IP packets containing configured source network addresses can be
forward by the switch.
For example:
1. IP Address: 192.168.3.2, IP Mask: 255.255.255.0; Network address 192.168.3.x (254 IP Addresses) can be
forwarded on this port
2. IP Address: 192.168.3.2, IP Mask: 255.255.255.255; Only IP 192.168.3.2 can be forwarded on the port.
DHCP: Allow the IP Address received from DHCP server to login to this switch and manage it. Only the IP
packets containing the source IP are allowed to be forwarded through the switch.
IP Address: IP Address, it can be one IP Address or a LAN
IP Mask: IP Subnet Mask, related to the IP Address
DHCP Server Allowed: Tick off the check-box under the port x to allow the DHCP Server on this
Port, valid port is Port 1-18.
Rate Limit Configuration
Select the Port number.
Policer: Set up the ingress bandwidth limit. Incoming traffic is discarded if the rate exceeds the value entered.
Pause frames are also generated if flow control is enabled. The format of the packet limits to unicast, broadcast
and multicast. Valid value of Port 1-18 is 128-3968 kbps. Default: No Limit
Shaper: Set up the egress bandwidth limit. Outgoing traffic is discarded if the rate exceeds the value entered.
Pause frames are generated if flow control is enabled. The format of the packet limits to unicast, broadcast and
multicast. Valid value of Port 1-18 is 128-3968. Default: No limit
Storm Control
Broadcast storms may occur when a device on your network is malfunctioning, or if application programs are not
well designed or properly configured. If there is too much broadcast traffic on your network, performance can be
severely degraded or everything can come to complete halt.
You can protect your network from broadcast storms by setting a threshold for broadcast traffic for each port. Any
broadcast packets exceeding the specified threshold are dropped then.
Storm Control Configuration
Note: In this mode, the received packets are filtered except the IP packets with configured source
network addresses.
