transmit the frames from the MAC address list in the port’s static MAC address
table.
4.2.2 Port Statistic and Port Status
Port Statistic calculates the statistics of each port, such as how many frames,
error frames, broadcast frames it has received, and so on.
Port Status indicates whether the port is linkup, linkdown or disabled, what
speed and duplex mode it is working on, and whether ow control is enabled
or disabled.
4.2.3 Storm Control
Storm control limits the amount of multicast, broadcast and UL (addresses
that have not been learned) frames accepted and forwarded by the device.
When Layer 2 frames are forwarded, broadcast, multicast and UL frames are
ooded to all ports on the relevant VLAN. This occupies bandwidth, and loads
all nodes on all ports.
A Storm is a result of an excessive amount of these frames simultaneously
transmitted across a network by a single port. Forwarded message responses
are heaped onto the network, straining network resources or causing the
network to time out. Storm control is enabled for all ports by defining the
packet type and the rate at which the packets are transmitted. The system
measures the incoming dened frame rates on each port, and discards the
frames when the rate exceeds a user-dened rate.
4.2.4 Port Description
Use a description word to indicate the port.
