DOC-CD again..ie default
port-channel load-balance
Use the port-channel load-balance global configuration command to set the
load-distribution method among the ports in the EtherChannel. Use the no
form of this command to return to the default setting.
port-channel load-balance {dst-mac | src-mac}
no port-channel load-balance
Syntax Description
dst-mac
Load distribution is based on the destination host MAC address. Packets to
the same destination are sent on the same port, but packets to different
destinations are sent on different ports in the channel.
src-mac
Load distribution is based on the source MAC address. Packets from different
hosts use different ports in the channel, but packets from the same host use
the same port.
Defaults
The default is src-mac.
