Configuring Link Aggregation

Chapter 9 Configuring Link Aggregation on the ML-Series Card

Each ML100-FX supports up to four FECs plus an additional POS channel, a port channel made up of the two POS ports. A maximum of four Fast Ethernet ports can bundle into one Fast Ethernet Channel (FEC) and provide bandwidth scalability up to 400-Mbps full-duplex Fast Ethernet.

Caution The EtherChannel interface is the Layer 2/Layer 3 interface. Do not enable Layer 3 addresses on the physical interfaces. Do not assign bridge groups on the physical interfaces because doing so creates loops.

Caution Before a physical interface is removed from an EtherChannel (port channel) interface, the physical interface must be disabled. To disable a physical interface, use the shutdown command in interface configuration mode.

Note Link aggregation across multiple ML-Series cards is not supported.

Note Policing is not supported on port channel interfaces.

Note The ML-Series does not support the routing of Subnetwork Access Protocol (SNAP) or Inter-Switch Link (ISL) encapsulated frames.

You can configure an FEC or POS channel by creating an EtherChannel interface (port channel) and optionally assigning a network IP address.

Configuring Fast EtherChannel

All interfaces that are members of an FEC should have the same link parameters, such as duplex and speed.

To create an EtherChannel interface, perform the following procedure, beginning in global configuration mode:

		Command	Purpose
	Step 1
	Step 1	Router(config)# interface port-channel	Creates the EtherChannel interface.
		channel-number
	Step 2
	Step 2	Router(config-if)# ip address ip-address	(Optional) Assigns an IP address and subnet mask
		subnet-mask	to the EtherChannel interface.
	Step 3
	Step 3	Router(config-if)# end	Exits to privileged EXEC mode.
	Step 4
	Step 4	Router# copy running-config startup-config	(Optional) Saves configuration changes to
			NVRAM.
