LAG formation rules

• The router can support up to 256 LAGs, and each LAG can contain up to 64 member ports.

• If the router is configured to support 32 LAGs by using the system-max trunk-num

command, the maximum number of LAG ports is 64.

• If the router is configured to support 64 LAGs by using the system-max trunk-num

command, the maximum number of LAG ports is 32.

• If the system-max trunk-num is set to 256, the maximum number of LAG ports supported

is 8.

• The default system-max trunk-num is set to 128, and each LAG can have up to 16 member

ports

• For 40G and 100G ports, the number of LAG FIDs is 128. The configurable ranges are

from 2 to 64 LAGs.

• When configuring a static or dynamic LAG, if trunk load sharing type is set to “per-packet” the

maximum number of “per-packet” trunks is set to 4.

• Ports can be in only one LAG group. All the ports in a LAG group must be connected to the

same device at the other end. For example, if port 1/4 and 1/5 in Device 1 are in the same

LAG group, both ports must be connected to ports in Device 2 or in Device 3. You cannot have

one port connected to Device 2 and another port connected to Device 3.

• All LAG member properties must match the primary port of the LAG with respect to the

following parameters:

• Port tag type (untagged or tagged port)

• Port speed and duplex

• TOS-based Configuration – All ports in the LAG must have the same TOS-based QoS

configuration before LAG deployment, During deployment the configuration on the primary

port is replicated to all ports and on undeployment, each port inherits the same TOS-based

QoS configuration.

To change port parameters, you must change them on the primary port. The software

automatically applies the changes to the other ports in the LAG.

• Using the system-max trunk-num num command, the device can support the following

LAG/member port configurations:

• 256 LAGs with each containing 8 member ports.

• 128 LAGs with each containing 16 member ports.

• 64 LAGs with each containing 32 member ports.

• 32 LAGs with each containing 64 member ports.

• Using the system-max trunk-num-100g num command, the device can support the following

40 GbE and 100 GbE LAG scalability configurations.

• 64 LAGs with each containing 2 member ports.

• 32 LAGs with each containing 4 member ports.

• 16 LAGs with each containing 8 member ports.

• 8 LAGs with each containing 16 member ports.

• 4 LAGs with each containing 32 member ports.

• 2 LAGs with each containing 64 member ports.

• The total number of ports in a trunk is controlled by the system-max trunk-num command for

both non-100G and 100G trunks.
