Trunk Group Rules
• You can configure up to 64 trunk groups on a Chassis device, and up to four trunk groups on the Fixed-port
devices.
• Each trunk group must start with a primary port. The primary port is always the lowest number in the port
range. For example, on the J4140A 10/100 module:
• Ranges for four-port trunk groups: 1 – 4, 5 – 8, 9 – 15, 16 – 20, 21 – 24
• Ranges for two-port trunk groups: 1 – 2, 3 – 4, 5 – 6, 7 – 8, 9 – 10, 11 – 12, 13 – 14, 15 – 16, 17 – 18, 19
– 20, 21 – 22, 23 – 24
NOTE: You can configure up to 12 trunk groups on an HP 9304M or HP 9308M 24-port 10/100 module.
The 24-port 10/100 modules have the following primary ports: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, and 23.
See Figure 9.6.
• Port assignment must be contiguous. The port range cannot contain gaps. For example, you can configure
ports 1, 2, 3, and 4 together as a trunk group but not ports 1, 3, and 4 (excluding 2).
• Port assignment cannot be across multiple trunk group boundaries. For example, on a Fixed-port device,
ports 4 and 5 cannot be in the same 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)
• Port speed and duplex
• QoS priority
