Trunk group connectivity to a server
To support termination of a trunk group, the server must have either multiple network interface
cards (NICs) or either a dual or quad interface card installed. The trunk server is designated as a
server with multiple adapters or a single adapter with multiple ports that share the same MAC and
IP address.
Figure 75 shows an example of a trunk group between a server and a device.

Trunk group rules
Table 43 lists the maximum number of trunk groups you can configure on a device and the valid
number of ports in a trunk group. The table applies to static and LACP trunk ports.
• You cannot configure a port as a member of a trunk group if 802.3ad link aggregation is
enabled on the port.
• Unlike other devices, trunk groups on devices listed in Table 43 are not classified as switch
trunk groups or server trunk groups.
• On PowerConnect B-Series TI24X devices, 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 “Flexible trunk group membership” on page 314.
• 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 “Flexible trunk group
membership” on page 314.
• You can select any port to be the primary port of the trunk group.
• You cannot combine Gbps and 10-Gbps ports in the same trunk group.
