LACP
LACP (Link Aggregation Control Protocol) trunks are similar to static port trunks, but they are more
flexible because LACP is compliant with the IEEE 802.3ad standard. Hence, it is interoperable
with equipment from other vendors that also comply with the standard. This page allows you to
enable LACP functions to group ports together to form single virtual links and change associated
settings, thereby increasing the bandwidth between the switch and other LACP-compatible
devices.
Label
Description
Port
Indicates the ID of each aggregation group. Normal indicates there is no
aggregation. Only one group ID is valid per port.
LACP Enabled
Lists each switch port for each group ID. Check to include a port in an
aggregation, or clear the box to remove the port from the aggregation. By
default, no ports belong to any aggregation group. Only full duplex ports can
join an aggregation and the ports must be in the same speed in each group.
Key
The Key value varies with the port, ranging from 1 to 65535. Auto will set the key
according to the physical link speed (10Mb = 1, 100Mb = 2, 1Gb = 3). Specific
allows you to enter a user-defined value. Ports with the same key value can join
in the same aggregation group, while ports with different keys cannot.
Role
Indicates LACP activity status. Active will transmit LACP packets every second,
while Passive will wait for a LACP packet from a partner (speak if spoken to).
Timeout
The Timeout controls the period between BPDU transmissions. Fast will transmit
LACP packets each second, while Slow will wait for 30 seconds before sending a
LACP packet.
Prio
The Prio controls the priority of the port, range 1-65535. If the
LACP partner wants to form a larger group than is supported by this device then
this parameter will control which ports will be active and which ports will be in a
backup role. Lower number means greater priority.
