Instruction Manual - NXA-ENET8-POE+
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.
NOTE:
Configuring the port partner sets the remote side of an aggregate link; i.e., the ports on the attached device. The command
attributes have the same meaning as those used for the port actor.
Timeout Mode
The timeout to wait for the next LACP data unit (LACPDU):
• Long Timeout - Specifies a slow timeout of 90 seconds. (This is the default setting.)
• Short Timeout - Specifies a fast timeout of 3 seconds.
The timeout is set in the LACP timeout bit of the Actor State field in transmitted LACPDUs. When
the partner switch receives an LACPDU set with a short timeout from the actor switch, the partner
adjusts the transmit LACPDU interval to 1 second. When it receives an LACPDU set with a long
timeout from the actor, it adjusts the transmit LACPDU interval to 30 seconds.
If the actor does not receive an LACPDU from its partner before the configured timeout expires,
the partner port information will be deleted from the LACP group.
When a dynamic port-channel member leaves a port-channel, the default timeout value will be
restored on that port.
When a dynamic port-channel is torn down, the configured timeout value will be retained. When
the dynamic port-channel is constructed again, that timeout value will be used.
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.
System MAC Address
The device MAC address assigned to each trunk.
Configure Aggregation Port - General
Port
Port identifier (Range: 1-10/26/28/52)
LACP Status
Enables or disables LACP on a port.
Configure Aggregation Port - Actor/Partner
Port
Port number (Range: 1-10/28)
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 - Actor: 1, Partner: 0)
Once the remote side of a link has been established, LACP operational settings are already in use
on that side. Configuring LACP settings for the partner only applies to its administrative state, not
its operational state.
NOTE:
Configuring the partner admin-key does not affect remote or local switch operation.
The local switch just records the partner admin-key for user reference.
By default, the actor's operational key is determined by port's link speed (1000f - 4, 100f - 3, 10f -
2), and copied to the admin key.
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)
• Setting a lower value indicates a higher effective priority.
• If an active port link goes down, the backup port with the highest priority is selected to replace
the downed link. However, if two or more ports have the same LACP port priority, the port with
the lowest physical port number will be selected as the backup port.
• If an LAG already exists with the maximum number of allowed port members, and LACP is
subsequently enabled on another port using a higher priority than an existing member, the
newly configured port will replace an existing port member that has a lower priority.
