IPv4, IPv6, and non-IP traffic handling on the E-Series
The table below presents the combinations of the
Table 20-7. The load-balance Commands and Port Channel Types

C-Series and S-Series load-balancing
For LAG hashing on C-Series and S-Series, the source IP, destination IP, source TCP/UDP port, and
destination TCP/UDP port are used for hash computation by default. For packets without a Layer 3 header,
FTOS automatically uses
IP hashing or MAC hashing should not be configured at the same time. If you configure an IP and MAC
hashing scheme at the same time, the MAC hashing scheme takes precedence over the IP hashing scheme.
To change the IP traffic load balancing default on the C-Series and S-Series, use the following command:
Command Syntax
[ no ] load-balance { ip-selection
[ dest-ip | source-ip ]} | { mac
[ dest-mac | source-dest-mac |
source-mac ]} | { tcp-udp enable }

Purpose
Replace the default IP 4-tuple method of balancing
traffic over a port channel. You can select one, two, or
all three of the following basic hash methods
ip-selection [ dest-ip | source-ip ]
traffic based on IP destination or source address.
mac [ dest-mac | source-dest-mac |
source-mac ]
—Distribute IPV4 traffic based on the
destination or source MAC address, or both, along with the
VLAN, Ethertype, source module ID and source port ID.
tcp-udp enable
—Distribute traffic based on TCP/UDP
source and destination ports.
