Packet type: You can assign the Rate for specific packet types based on packet
number per second. The packet types of the Ingress Rule listed here include
Broadcast, DLF (Destination Lookup Failure) and Multicast. Choose
Enable/Disable to enable or disable the storm control for a specific port.
Rate: This column allows you to manually assign the limit rate of the port. The
unit is packets per second. The limit range is from 1 to 262143 packets/sec, zero
means no limit. The maximum available value of Fast Ethernet interface is
148810 and is the maximum packet number of the 100M throughput.
Enter the Rate field of the port you want assign, type the new value and click
Enter key first. After assigned or changed the value for all the ports you want
configure. Click on Apply to apply the configuration of all ports. The Apply
command applied all the ports’ storm control value.
4.3.5 Port Trunking
Port Trunking configuration allows you to group multiple Ethernet ports and to
increase link bandwidth. The aggregated ports can be viewed as one physical port
so that the bandwidth is higher than merely one single Ethernet port. The
member ports of the same trunk group can balance the loading and backup for
each other. Port Trunking feature is usually used when you need higher
bandwidth for backbone network. This is an inexpensive way for you to transfer
more data.
There are some different descriptions for the port trunking. Different
manufacturers may use different descriptions for their products, like Link
Aggregation Group (LAG), Link Aggregation Control Protocol, Ethernet Trunk,
Ether Channel…etc. Most of the implementations now conform to IEEE standard,
802.3ad.
The aggregated ports can interconnect to the other switch which also supports
Port Trunking. The switch supports two types of port trunking. One is Static Trunk,
the other is 802.3ad. When the other end uses 802.3ad LACP, you should assign
802.3ad LACP to the trunk. When the other end uses non-802.3ad, you can then
use Static Trunk. In practical, the Static Trunk is suggested.
There are 2 configuration pages, Aggregation Setting and Aggregation Status.
