Understanding Link Aggregation
Link aggregation provides the following benefits:
•
•
•
The EtherChannel interface, consisting of multiple Fast Ethernet, Gigabit Ethernet or POS interfaces, is
treated as a single interface, which is called a port channel. You must perform all EtherChannel
configurations on the EtherChannel interface (port channel) rather than on the individual member
Ethernet interfaces. You can create the EtherChannel interface by entering the interface port-channel
interface configuration command. Each ML100T-12 supports up to 7 Fast EtherChannel (FEC)
interfaces or port channels (6 Fast Ethernet and 1 POS). Each ML1000-2 supports up to 2 Gigabit
EtherChannel (GEC) interfaces or port channels (1 Gigabit Ethernet and 1 POS.)
EtherChannel connections are fully compatible with IEEE 802.1Q trunking and routing technologies.
802.1Q trunking can carry multiple VLANs across an EtherChannel.
Cisco's FEC technology builds upon standards-based 802.3 full-duplex Fast Ethernet to provide a
reliable high-speed solution for the campus network backbone. FEC provides bandwidth scalability
within the campus by providing up to 400-Mbps full-duplex Fast Ethernet on the ML100-12.
Cisco's GEC technology provides bandwidth scalability by providing 2-Gbps full-duplex aggregate
capacity on the ML1000-2.
Cisco's POS channel technology provide bandwidth scalability by providing up to 48 STSs or VC4-16c
of aggregate capacity on either the ML100-12 or the ML1000-2.
Note
Link aggregation across multiple ML-Series cards is not supported.
Note
Policing is not supported on port channel interfaces.
Configuring EtherChannel
You can configure a FEC or a GEC by creating an EtherChannel interface (port channel) and assigning
a network IP address. All interfaces that are members of a FEC or a GEC 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
Step 1
Router(config)# interface port-channel
channel-number
Step 2
Router(config-if)# ip address ip-address
subnet-mask
Step 3
Router(config-if)# end
Step 4
Router# copy running-config startup-config

Purpose
Creates the EtherChannel interface. You can
configure up to 6 FECs on the ML100T-12 and
1 GEC on the ML1000-2.
Assigns an IP address and subnet mask to the
EtherChannel interface (required only for Layer 3
EtherChannel).
Exits to privileged EXEC mode.
(Optional) Saves configuration changes to
NVRAM.
