Configuring the Ports

Guideline 5: Maintaining Cabling Sequence Based on Port Number
When cabling a trunk, it is important that the order of the connections
be identical on both nodes. The lowest numbered port in a trunk on one
device must be connected to the lowest numbered port of the trunk on
the other device, the next lowest numbered port must be connected to
the next lowest numbered port on the other device, and so on.
Guideline 6: Configuring the Port Parameters of a Port Trunk
The ports in a trunk automatically assume the same configuration (such
as VLAN membership) as the configuration of the lowest numbered port.
For example, if you create a trunk consisting of ports 7 and 8, port 7 is
the master port and its configuration is propagated to port 8. As long as
the ports are configured as a trunk, you must not change any of the
attributes of any ports that might conflict with the settings of the master
port.
Creating a Port
Trunk
This section contains the procedure for creating a port trunk.
Caution
Do not connect the cables to the port trunk on the switch until after
you have created the port trunk. Connecting the cables prior to
creating the trunk will result in data loops in your network topology.
To create a port trunk, perform the following procedure:
1. From the Omega Main Menu, select System configuration.
The System Configuration menu in Figure 8 on page 43 is displayed.
2. Select System switch configuration.
The System switch configuration menu in Figure 16 on page 52 is
displayed.
3. Select Port Trunking in the 10/100M Speed Port.
4. Specify the ports that will be the port trunk and press . You
can use either of the following formats to enter the port numbers:
Single, consecutive ports (for example, 7,8)
Range of ports (for example, 7-10)
5. Return to the Main Menu.
6. To confirm the creation of a port trunk, select Port status and
configuration from the Omega main menu to display a list of ports. All
of the ports in a port trunk are automatically assigned the name
“Trunk” along with a number to help identify the port trunk.
