Description
This command creates an LACP aggregator. Note the following when
creating a new aggregator:
ˆ You can specify either a name or an adminkey but not both when
creating a new aggregator.
ˆ When you create a new aggregator by specifying a name, the
adminkey is based on the operator key of the lowest numbered port in
the aggregator.
ˆ When you create an aggregator by specifying an adminkey, the
aggregator’s default name is DEFAULT_AGG followed by the port
number of the lowest numbered port in the aggregator. For instance,
an aggregator of ports 1.12 to 1.16 would be given the name
DEFAULT_AGG12.
ˆ Before creating an aggregator, you should verify that the ports that will
be members of the aggregator are set to Auto-Negotiation or 100
Mbps, full-duplex. Aggregate trunks do not support half-duplex mode.
ˆ All ports in an aggregator must be untagged ports of the same VLAN.
ˆ You cannot change the name or adminkey of an existing aggregator.
That function requires deleting the aggregator and recreating it.
Caution
Do not connect the cables to the ports of the aggregator on the
switch until after you have configured LACP and the aggregators on
both devices that will be interconnected by the trunk. Connecting the
cables before configuring the aggregators and activating the
protocol will create a loop in your network topology. Data loops can
result in broadcast storms and poor network performance.
Examples
The following command creates an LACP aggregator named “sw_agg_1”
of ports 1.1 through 1.4. The load distribution method is source MAC
address. Since the aggregator is being created by name, the default
operator key for port 1, the lowest numbered port in the aggregator,
becomes the adminkey:
create lacp aggregator=sw_agg_1 port=1.1-1.4
distribution=macsrc
The following command creates an LACP aggregator of ports 1.10, 2.12,
2.15 to 2.18 with an adminkey number of 0x7A. The default name for the
aggregator is DEFAULT_AGG10 because the command specifies an
adminkey and because port 10 is the lowest numbered port in the
aggregator. Since no load distribution method is specified, the source and
destination MAC addresses load distributed method is used by default:
create lacp adminkey=0x7A port=1.10,2.12,2.15-2.18
