SSE-G2252/SSE-G2252P Switches User's Manual
• Ports are only allowed to join the same Link Aggregation Group (LAG) if (1) the
LACP port system priority matches, (2) the LACP port admin key matches, and (3)
the LAG admin key matches (if configured). However, if the LAG admin key is set,
then the port admin key must be set to the same value for a port to be allowed to
join that group.
NOTE: If the LACP admin key is not set when a channel group is formed (i.e., it
has a null value of 0), the operational value of this key is set to the same value
as the port admin key used by the interfaces that joined the group (see the
"show lacp"
Parameters
These parameters are displayed in the web interface:
Configure Aggregator
• Admin Key – LACP administration key is used to identify a specific link aggregation
group (LAG) during local LACP setup on the switch. (Range: 0-65535)
Configure Aggregation Port - General
• Port – Port identifier. (SSE-G2252/P: 1-52)
• LACP Status – Enables or disables LACP on a port.
Configure Aggregation Port - Actor/Partner
• Port – Port number. (SSE-G2252/P: 1-52)
• Admin Key – The LACP administration key must be set to the same value for ports
that belong to the same LAG. (Range: 0-65535; Default: 1)
By default, the Actor Admin Key is determined by port's link speed, and copied to
Oper Key. The Partner Admin Key is assigned to zero, and the Oper Key is set
based upon LACP PDUs received from the Partner.
• System Priority – LACP system priority is used to determine link aggregation group
(LAG) membership, and to identify this device to other switches during LAG
negotiations. (Range: 0-65535; Default: 32768)
System priority is combined with the switch's MAC address to form the LAG
identifier. This identifier is used to indicate a specific LAG during LACP negotiations
with other systems.
• Port Priority – If a link goes down, LACP port priority is used to select a backup
link. (Range: 0-65535; Default: 32768)
NOTE: Configuring LACP settings for a port only applies to its administrative
state, not its operational state, and will only take effect the next time an
aggregate link is established with that port.
