Function name:
Bandwidth Management
Function description:
Bandwidth Management function is used to set up the limit of Ingress and Egress
bandwidth for each port.
Note: Each port of the switch owns 16KB packet buffer. The packet buffer size will
be reduced when the bandwidth rate limitation is enabled, which may cause that
jumbo frame cannot be forwarded.
Please avoid enabling jumbo frame and bandwidth rating functions at the same time.
Parameter description:
Port Number: Choose the port that you would like this function to work on
it. Valid range of the port is 1~8.
All Traffic for Ingress Rate Limiting (Policing): Set up the limit of Ingress bandwidth for
the port you choose. Incoming traffic will be discarded if the
rate exceeds the value you set up in Data Rate field. Pause
frames are also generated if flow control is enabled. The
format of the packet limits to unicast, broadcast and
multicast. Valid range is 0~1000
Broadcast & Multicasat for Ingress Rate Limiting (Policing): Set up the limit of Ingress
bandwidth for the port you choose. Incoming traffic will be
discarded if the rate exceeds the value you set up in Data
Rate field. The format of the packet limits to broadcast and
multicast. Valid range is 0~1000.
All Traffic for Egress Rate Limiting (Shaping): Set up the limit of Egress bandwidth for the
port you choose. Packet transmission will be delayed if the
rate exceeds the value you set up in Data Rate field. Traffic
may be lost if egress buffers run full. The format of the
