The Spanning Tree Protocol will treat a trunked port group as a single link, on the switch level. On the
port level, the STP will use the port parameters of the master port in the calculation of port cost and in
determining the state of the port trunk group. If two redundant trunked groups are configured on the
switch, STP will block one entire group – in the same way STP will block a single port that has a
redundant link.
To configure port trunk groups, click the Add button to add a new trunk group and use the menu Port
Trunking Configuration menu (see example below) to set up trunk groups. To change or delete a port
trunk group, click the Modify or Delete option in the Current Trunk Group Entries Table.
The user-changeable parameters in the Switch are as follows:
Select Slot Number
Select Group ID
Group Name
State
Port Member
Relevant CLI command sets for link aggregation are
config
link_aggregation.

Choose the slot on which you wish to set up a trunk group. Trunk groups must
be confined to ports on a single module.
Select an ID number for the group.
Type in a name for the group (optional).
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.
Choose the members of the trunked group. Up to 8 ports per group can be
assigned to a group.
