LACP Settings
The switch supports both static trunking and dynamic Link Aggregation
Control Protocol (LACP), which is specified in IEEE 802.3ad. Static trunks
have to be manually configured at both ends of the link, on the other hand,
LACP configured ports can automatically negotiate a trunked link with LACP-
configured ports on another device. You can configure any number of ports
on the switch as LACP, as long as they are not already configured as part of a
static trunk. If ports on another device are also configured as LACP, the switch
and the other device will negotiate a trunk link between them. If an LACP
trunk consists of more than eight ports, all other ports will be placed in a
standby mode. Should one link in the trunk fail, one of the standby ports will
automatically be activated to replace it.
You can use the LACP Setting page to configure LACP for each port.
Enabling LACP
1. On the LACP Setting page, click the box under the column labeled “LACP
Enabled on Port” for the ports you want to enable LACP.
2. Input a key value for the Link Aggregate Group.
3. Click APPLY.
Disabling LACP
1. On the LACP Setting page, click the box under the column labeled “LACP
Enabled on Port” to remove the check mark for the ports you want to
disable LACP.
2. Click APPLY.
Field Attributes
• Port – The port number.
• LACP Enabled on Port – Allows LACP to be enabled or disabled.
When the box is checked, LACP is enabled.
• Key Value (0..255, 0 means autogenerated key) – Ports in an
aggregated link group must have the same LACP port Key. For a port
to be allowed to join an aggregated group, the port Key must be set
to the same value. When set to zero, the port Key is automatically set
by the switch.
