Chapter 9: Port Trunking Commands
134
Caution
Do not connect the cables to the trunk ports on the switches 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.
Examples
The following command creates a port trunk using ports 3 through 6.
The command names the trunk “load22” and sets the load distribution
method to destination MAC address.
create switch trunk=load22 port=3-6 select=macdest
The following command creates a port trunk consisting of ports 15,17,
and 23. The command names the trunk “trunk4”. No load distribution
method is specified, so the default source and destination MAC
addresses is used:
create switch trunk=trunk4 port=15,17,23
