port channel
load-balance
This command sets the load-distribution method among ports in aggregated links
(for both static and dynamic trunks). Use the no form to restore the default setting.
Syntax
port channel load-balance {dst-ip | dst-mac | src-dst-ip | src-dst-mac | src-ip
| src-mac}
no port channel load-balance
dst-ip - Load balancing based on destination IP address.
dst-mac - Load balancing based on destination MAC address.
src-dst-ip - Load balancing based on source and destination IP address.
src-dst-mac - Load balancing based on source and destination MAC
address.
src-ip - Load balancing based on source IP address.
src-mac - Load balancing based on source MAC address.
Default Setting
src-dst-ip
Command Mode

Command Usage
◆ This command applies to all static and dynamic trunks on the switch.
◆ To ensure that the switch traffic load is distributed evenly across all links in a
trunk, select the source and destination addresses used in the load-balance
calculation to provide the best result for trunk connections:
■
dst-ip: All traffic with the same destination IP address is output on the
same link in a trunk. This mode works best for switch-to-router trunk links
where traffic through the switch is destined for many different hosts. Do
not use this mode for switch-to-server trunk links where the destination IP
address is the same for all traffic.
■
dst-mac: All traffic with the same destination MAC address is output on the
same link in a trunk. This mode works best for switch-to-switch trunk links
where traffic through the switch is destined for many different hosts. Do
not use this mode for switch-to-router trunk links where the destination
MAC address is the same for all traffic.
■
src-dst-ip: All traffic with the same source and destination IP address is
output on the same link in a trunk. This mode works best for switch-to-
