• Layer 3 requirements:

The LAG is rejected if any of the secondary LAG port has any Layer 3 configurations, such as IPv4

or IPv6 address, OSPF, RIP, RIPNG, IS-IS, and so on.

• Layer 4 (ACL) requirements:

All LAG ports must have the same ACL configurations; otherwise, the LAG is rejected.

• 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 dual-mode

‐ Default port speed and duplex

‐ Configured port speed and duplex

‐ TOS-based Configuration - 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.

• Make sure the device on the other end of the LAG link can support the same number of ports in the

link.

• Legacy ports and 48 Gbps copper ports cannot be members of the same LAG in hardware

configurations such as the following:

‐ 48-port 10/100/1000 Mbps (RJ45) Ethernet PoE interface module (SX-FI48GPP) and IPv4/

IPv6 interface modules or management modules with user ports.

• Combination of different generations of ports cannot be members of the same LAG under the

following hardware configurations:

‐ 24-port fiber and copper Ethernet PoE/Fiber interfaces (SX-FI24GPP, SX-FI24GF) and

IPv4/IPv6 interface modules or management modules with user ports

‐ 2-port 10G and 8-port 10G interfaces (SX-FI8XG, SX-FI2XG) and the IPv4/IPv6 interface

modules or management modules with user ports

• The FastIron SX chassis supports up to 12 ports per LAG and a maximum of 255 LAGs only when

the following third generation interface modules are installed in the chassis:

‐ SX-FI48GPP--48-port 10/100/1000 Mbps Ethernet PoE interface module

‐ SX-FI24GPP--24-port Gigabit Ethernet copper interface module

‐ SX-FI24HF--24-port Gigabit Ethernet fiber interface module

‐ SX-FI2XG--2-port 10 Gigabit Ethernet interface module

‐ SX-FI8XG--8-port 10 Gigabit Ethernet interface module

• Cross module LAG is only supported between the same generation SX cards.

• LAG is supported on 1-GbE,10-GbE or 40-GbE ports.

• You cannot combine 1-GbE and 10-GbE ports in the same LAG.

• 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).

• Although the FastIron devices have port ranges, they do not apply to LAGs.

• You can select any port to be the primary port of the LAG.

• Make sure the device on the other end of the LAG can support the same number of ports in the link.

For example, if you configure a 3-port LAG on the FSX and the other end is a different type of switch,

make sure the other switch can support a 3-port LAG.

• All the ports must be connected to the same physical or logical device at the other end.
