Trunk group rules
Table lists the maximum number of trunk groups you can configure on a Dell PowerConnect device
and the valid number of ports in a trunk group. The table applies to static and LACP trunk ports.
• In a hardware configuration with a IPv4 and IPv6 interface modules or management modules
with user ports, legacy ports and 48 Gbps copper ports cannot be members of the same trunk
group.
• You cannot configure a port as a member of a trunk group if 802.3ad link aggregation is
enabled on the port.
• Dell PowerConnect devices, trunk groups on devices listed in Table are not classified as switch
trunk groups or server trunk groups.
• Trunking is supported on 10-GbE ports.
• You cannot combine 1-Gbps and 10-Gbps ports in the same trunk group.
• Port assignment on a module need not be consecutive. The port range can contain gaps. For
example, you can configure ports 1, 3, and 4 (excluding 2). Refer to “Support for flexible trunk
group membership” on page 398.
• Although the PowerConnect devices have port ranges, they do not apply to trunk groups.
• You can select any port to be the primary port of the trunk group.
• All the ports must be connected to the same device at the other end.
• All trunk group member properties must match the lead port of the trunk group with respect to
the following parameters:
• port tag type (untagged or tagged port)
