The user-changeable parameters are as follows:
Parameter Description
Group ID
Select an ID number for the group, between
1
and 32.
State
Trunk groups can be toggled between
Enabled
and
Disabled
. This is used to turn a port
trunking group on or off. This is useful for diagnostics, to quickly isolate a bandwidth
intensive network device or to have an absolute backup aggregation group that is not under
automatic control.
Master Port
Choose the Master Port for the trunk group using the pull-down menu.
Unit
Select the switch in the switch stack to be modified.
Member Ports
Choose the members of a trunked group. Up to eight ports per group can be assigned to a
group.
Flooding Port
A trunking group must designate one port to allow transmission of broadcasts, multicasts and
unknown unicasts.
Active Port
Shows the port that is currently forwarding packets.
Type
This pull-down menu allows users to select between
Static
and
LACP
(Link Aggregation
Control Protocol). LACP allows for the automatic detection of links in a Port Trunking Group.
