Caution
Do not connect the cables to the trunk ports on the devices until after
you have created the trunk in the management software. Connecting
the cables before configuring the software will create a loop in your
network topology. Data loops can result in broadcast storms and
poor network performance.
Note
Before creating a static port trunk, examine the speed, duplex mode,
and flow control settings of the lowest numbered port to be in the
trunk. Check to be sure that the settings are correct for the end node
to which the trunk will be connected. When you create the trunk, the
AT-S63 Management Software copies the settings of the lowest
numbered port in the trunk to the other ports so that all the settings
are the same.
You should also check to be sure that the ports are untagged
members of the same VLAN. You cannot create a trunk of ports that
are untagged members of different VLANs.
Note
A port that already belongs to a static port trunk must be removed
from its current assignment before it can be added to another port
trunk. To remove ports from a static trunk, see “DELETE SWITCH
TRUNK” on page 148.
Examples
The following command creates a static port trunk using ports 2.3 to 2.6.
The command names the trunk “load22” and sets the load distribution
method to destination MAC address.
create switch trunk=load22 port=2.3-2.6 select=macdest
The following command creates a port trunk consisting of ports 1.15,4.17,
and 4.22. The trunk is named “trunk4”. No load distribution method is
specified, so the default setting, source and destination MAC addresses, is
used:
create switch trunk=trunk4 port=1.15,4.17,4.22
