6.  Select one or more interfaces by taking one of the following actions:
• To configure a single interface, select the check box associated with the interface, or 
type the interface number in the Go T
o Interface field and click the Go button. 
• To configure multiple interfaces with the same settings, select the check box 
associated with each interface. 
• To configure all interfaces with the same settings, select the check box in the heading 
row
.
7.  In the 
LACP Priority field, specify the LACP priority value for the selected interfaces.
This value specifies the interface’s link aggregation priority relative to the devices at the 
other ends of the links on which link aggregation is enabled. A higher value indicates a 
lower priority. 
The range is 1 to 65535. The default value is 128.
8.  In the Timeout field, configure the administrative LACP time-out value:
• Long. Specifies a long time-out value.
•
Short. Specifies a short time-out value.
9.  Click the Apply button.

Configure VLANs
Adding virtual LAN (VLAN) support to a Layer 2 switch offers some of the benefits of both 
bridging and routing. Like a bridge, a VLAN switch forwards traffic based on the Layer 2 
header, which is fast, and like a router, it partitions the network into logical segments, which 
provides better administration, security, and management of multicast traffic.
By default, all ports on the switch are in the same broadcast domain. VLANs electronically 
separate ports on the same switch into separate broadcast domains so that broadcast 
packets are not sent to all the ports on a single switch. When you use a VLAN, users can be 
grouped by logical function instead of physical location.
Each VLAN in a network is assigned an associated VLAN ID, which appears in the IEEE 
802.1Q tag in the Layer 2 header of packets transmitted on a VLAN. 
An end station can omit 
the tag, or the VLAN portion of the tag, in which case the first switch port to receive the 
packet can either reject it or insert a tag using its default VLAN ID. A port can handle traf
fic for 
more than one VLAN, but it can support only one default VLAN ID.
