EtherChannel balances traffic load across the links in a channel.
Load balancing can be based upon the variables listed. The default load
balancing method varies among the Catalyst models.
Load balancing is
applied globally for all EtherChannel bundles in the switch. To configure
EtherChannel load balancing, use the port-channel load-balancetype command. The load-balancing keywords are as follows:
src-mac – Source MAC addresses
dst-mac – Destination MAC addresses
src-dst-mac – Source and destination MAC addresses
src-ip – Source IP addresses
dst-ip – Destination IP addresses
src-dst-ip – Source and destination IP addresses
(default)
src-port – Source TCP/User Datagram Protocol (UDP)
port
dst-port – Destination TCP/UDP port
src-dst-port – Source and destination TCP/UDP port
Configuring and Verifying EtherChannel Load Balancing This
example shows how to configure and verify EtherChannel load balancing.
The purpose of this lab is to provide more bandwidth between Ethernet
switches. Two 100-Mb links will be combined together to form a full duplex
200-Mb link.
