Additional Trunk Group Rules for Gigabit Ethernet Modules on Chassis Devices
• You can configure a multi-slot trunk group on two Gigabit Ethernet modules.
• You can configure a maximum of eight ports in the trunk group.
• You can configure up to two groups of ports to make the trunk group and the groups must be alike. For
example, you can group two sets of two ports together or two sets of four ports together but you cannot group
a set of two ports with a set of four ports. Each group of ports can contain two or four ports.
• Each group of ports must begin with a primary port. On Gigabit Ethernet modules, the primary ports are 1, 3,
5, and 7.
• When you specify the ports in the trunk group, you must specify them in ascending numerical order,
beginning with the primary port. For example, to specify a group containing ports 1/1 – 1/4 and 3/1 – 3/4, you
must specify them in the order shown. You cannot specify 3/1 – 3/4 first.
• Port configuration for each trunk group is based on the configuration of the primary port. To change port
parameters, you must change them on the primary port. The software automatically applies the changes to
the other ports in the trunk group.
• If you plan to configure ports on a module into a server trunk group, use the following additional guidelines:
• The management module(s) and the module that has the server trunk group’s ports must be in the same
set of slots (slots 1 – 7 or 9 – 15). Do not place the management module(s) and the module containing
the trunk ports in separate sets of slots.
• Do not place the management module(s) or the module that has the server trunk group’s ports in slot 8.
These guidelines apply to a server trunk group that is configured on a single module or on a pair of modules
(multi-slot trunk group). You do not need to follow these guidelines for a switch trunk group.
