Chapter 7: LACP Port Trunks
110 Section I: Basic Operations
ˆ
When creating a new aggregator, you can specify either a name for
the aggregator or an adminkey, but not both. If you specify a name, the
adminkey is based on the operator key of the lowest numbered port in
the aggregator. If you specify an adminkey, the default name is
DEFAULT_AGG followed by the port number of the lowest numbered
port in the aggregator. For example, an aggregator of ports 12 to 16 is
assigned the default name DEFAULT_AGG12.
ˆ
Prior to creating an aggregate trunk between an Allied Telesis device
and another vendor’s device, refer to the vendor’s documentation to
determine the maximum number of active ports the device can support
in a trunk. If the number is less than eight, the maximum number for
the AT-9400 Switch, you should probably assign it a higher system
LACP priority than the AT-9400 Switch. If it is more than eight, assign
the AT-9400 Switch the higher priority. This can help avoid a possible
conflict between the devices if some ports are placed in the standby
mode when the devices create the trunk. For background information,
refer to “LACP System Priority” on page 106.
