Configuration notes
There are several trunk group rules. For a full description of these trunking rules, refer to the
Brocade 6910 Ethernet Access Switch Configuration Guide.
• You can use both static trunk groups and 802.3ad trunking on the same device. However, you
can use only one type of trunking for a given port. For example, you can configure port 1/1 as
a member of a static trunk group or you can enable 802.3ad link aggregation on the port, but
you cannot do both.
• The ports in a trunk group make a single logical link. Therefore, all the ports in a trunk group
must be connected to the same device at the other end.
• If you connect physical cables before configuring the trunk groups and then reboot, traffic on
the ports can create a spanning tree loop.
Common diagnostic scenarios
Trunk transaction failed; ports overlap with other trunks.
With a static trunk, you must first remove the existing trunk and reconfigure a new one. If you are
using dynamic trunk configuration, you would be able to add a port dynamically in the trunk.
