Object Description
Trunk The Trunk number.
Member Select the member of the Trunk here.
Storm Control Configure the storm control for the Trunk here. All member ports of the Trunk share the same setting.
Broad Control Enable or disable the broadcast control.
Multicast
Control Enable or disable the multicast control, enabling multicast control will also enable broadcast control.
UL Control Enable or disable the UL control, enabling UL control will also enable broadcast control and multicast
control.
Limit Rate Indicates the maximum rate (kilobytes per second) at which the controlled packets configure above
are forwarded. For the 1000M port，if set the value of 64K，the actual value is about 70Kbps。
All Trunk By operating on this field expediently, you can set the values of all Trunk in the corresponding field.
Select All Select all Trunk members in the list.
Clean Up Clean up the Trunk member list.

3.9 Priority Setting
The priority setting of the switch can be set to “Disable”, “Port-Based” or “IEEE802.1p”.
The priority setting menus include the tree sub-menus:
„ Priority mode
„ Port-Based priority
„ Port Default priority
„ 802.1p Priority class
3.9.1 Priority mode
The switch provided three priority modes: “Disable”, “Port-Based” or “IEEE802.1p”. The priority rule can be set to
“Weighted” or “Fixed”.
The switch classifies the ingress packets into four classes: “lowest”, “lower”, “higher” and “highest”. When priority rule
is configured as "weighted", a 1,2,4,8 weighting is applied to forward these packets. When "fixed" is selected, all packets
with top priority egress for a switch port until that priority's queue is empty, then the packets with next lower priority.
Example: In case of port-based priority mode:
If "weighted" is configured and the priority classes of four switch ports a, b, c and d are configured as lowest, lower, higher
and highest respectively, when the packets entering from these four ports are queued at one egress port, the switch then
forwards 8 d's packets, 4 c's packets, 2 b's packets and one a's packet at a time.
If "fixed" is configured and the priority classes of four switch ports a, b, c and d are configured as lowest, lower, higher and
highest respectively, all d's packets are forwarded first, then c, b, a. The screen in Figure 3-29 appears.
