Note
Among the ports comprising the aggregation group, the port with the smallest port number will be the master port.
The setting of an aggregation group immediately after a link aggregation is created will inherit the same setting as that
of the master port. The values different from the master port are as follows:
−
"link-pass-through" set to each comprising port will be dissolved.
−
The MAC address table set to each comprising port will be cleared.
−
The value of "spanning-tree port-path-cost" will change in accordance with the number of comprising ports.
When changing the setting of an aggregation group already created, if the following conditions are met, the
aggregation group will be temporarily in link down state and link up again and the port setting becomes default.
−
When the master port is deleted.
−
When the master port is changed.
−
When protocol or lacp-mode parameter is changed.
The port which is used as uplink cannot be specified as an aggregation port.
Example
Set a static link aggregation with ports 1 and 2 as aggregation group number 1.
And then move to the interface edit mode of the aggregation group, and set default VLAN ID to 2.
xg(config)# link-aggregation agg-port 1 protocol none port 1 2
xg(config)# interface agg-port 1
xg(config-agg)# port-vlan-id vlan 2
Set a link aggregation of LACP mode with ports 3, 4, and 5 as aggregation group number 2.
−
Comprising ports : 3, 4, 5
−
LACP mode : active
−
Distribution method : distribution by destination MAC
−
Link up condition minimum number of ports: 2
xg(config)# link-aggregation agg-port 2 protocol lacp lacp-mode active
load-balance dst-mac minimum-port 2 port 3 4 5
5.7.3 lacp system-priority
Function
Sets the system priority used in LACP.
This system priority is used as information to identify switches in LACP, but usually it is not necessary to be changed.
Use the no form to return to the default setup.
Prompt
xg(config)#
Command syntax
lacp system-priority <1-65535>
no lacp system-priority
Parameter
system-priority <1-65535>
Specifies the system priority of LACP in the range of 1 to 65535.
Command type
Configuration command
Default
32768
Message
% Unable to set port priority
Explanation
Since aggregation groups do not exist, the port priority cannot be set.
Solution
After creating an aggregation group, execute it again.
Example
Set LACP system priority to 10000.
xg(config)# lacp system-priority 10000
