You can use the Trunk Configuration page to view and edit trunks. The number of trunks on the system
is fixed, and all trunks are disabled by default. You can enable, disable, and edit settings for each
trunk. Click

The following information displays for each trunk.
Table 38. Trunk Configuration Fields
Field
Description
Trunk
The trunk ID.
Name
The configurable trunk name, which is the same as the trunk ID by default.
Type
Trunks can be either dynamic or static, but not both:
Dynamic—Dynamic trunks use the Link Aggregation Control Protocol (LACP, IEEE
standard 802.3ad). An LACP-enabled port automatically detects the presence of other
aggregation-capable network devices in the system and exchanges Link Aggregation
Control Protocol Data Units (LACPDUs) with links in the trunk. The PDUs contain infor-
mation about each link and enable the trunk to maintain them.
Static—Static trunks are assigned to a bundle by the administrator. Members do not
exchange LACPDUs. A static trunk does not require a partner system to be able to
aggregate its member ports. This is the default port type.
Note that the loop protection feature is not supported on dynamic trunks. If loop protection is
enabled on a static trunk and the trunk is changed to a dynamic trunk, loop protection is
disabled.
Admin Mode
Whether the trunk is administratively enabled or disabled. This feature is enabled by default.
Link Status
Indicates the operational status of the trunk interface, which can be Up, Up (SFP) for ports
with an installed SFP transceiver, or Down.
Members
The ports that are members of the trunk. By default, no ports belong to any trunk.
Active Ports
The ports that are actively participating members of a trunk. A member port that is
operationally or administratively disabled or does not have a link is not an active port.
