IPv4, IPv6, and non-IP traffic handling on <strong>the</strong> E-<strong>Series</strong><br />

The table below presents <strong>the</strong> different combinations of <strong>the</strong> load-balance command and <strong>the</strong> effect on traffic<br />

types.<br />

Table 19 The load-balance Commands and Port Channel Types<br />

<strong>Configuration</strong> Commands<br />

Default (IP 5-tuple)<br />

load-balance ip-selection 3-tuple<br />

Switched<br />

IP Traffic<br />

C-<strong>Series</strong> and S-<strong>Series</strong> load-balancing<br />

IP Traffic<br />

(IPv4 only)<br />

Packet-based MAC-based<br />

MAC-based Packet-based MAC-based<br />

For LAG hashing on C-<strong>Series</strong>, <strong>the</strong> source IP, destination IP, source TCP/UDP port, and destination TCP/<br />

UDP port are used <strong>for</strong> hash computation by default. For packets without a Layer 3 header, <strong>FTOS</strong><br />

automatically uses load-balance mac source-dest-mac.<br />

IP hashing or MAC hashing should not be configured at <strong>the</strong> same time. If you configure an IP and MAC<br />

hashing scheme at <strong>the</strong> same time, <strong>the</strong> MAC hashing scheme takes precedence over <strong>the</strong> IP hashing scheme.<br />

To change <strong>the</strong> IP traffic load balancing default on <strong>the</strong> C-<strong>Series</strong> and S-<strong>Series</strong>, use <strong>the</strong> following command in<br />

CONFIGURATION mode:<br />

Command Syntax Command Mode Purpose<br />

[no] load-balance {ip-selection<br />

[dest-ip | source-ip]} | {mac<br />

[dest-mac | source-dest-mac |<br />

source-mac]} | {tcp-udp enable}<br />

CONFIGURATION Replace <strong>the</strong> default IP 4-tuple method of balancing<br />

traffic over a port channel. You can select one, two,<br />

or all three of <strong>the</strong> following basic hash methods<br />

ip-selection [dest-ip | source-ip]—Distribute IP traffic<br />

based on IP destination or source address.<br />

mac [dest-mac | source-dest-mac | source-mac]—<br />

Distribute IPV4 traffic based on <strong>the</strong> destination or source<br />

MAC address, or both, along with <strong>the</strong> VLAN, E<strong>the</strong>rtype,<br />

source module ID and source port ID.<br />

tcp-udp enable—Distribute traffic based on TCP/UDP<br />

source and destination ports.<br />
