Note: Each port on the switch has a 16KB packet buffer. The packet buffer size will be reduced
when the bandwidth rate limitation is enabled, which may cause the jumbo frame to not be
forwarded. It is recommended to avoid enabling jumbo frame and bandwidth rating functions at
the same time.
Parameter description:
Port Number:
Choose the port to use for bandwidth management. 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 chose. 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 & Multicast 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 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 in Data Rate field. Traffic may be lost if egress
buffers run full. The format of the packet limits to unicast, broadcast and multicast. Valid range
is 0~1000.
