E-Series load-balancing
On the E-Series, the default load-balance criteria are a 5-tuple, as follows:
• IP source address
• IP destination address
• Protocol type
• TCP/UDP source port
• TCP/UDP destination port
Balancing may be applied to IPv4, switched IPv6, and non-IP traffic. For these traffic types, the
IP-header-based hash and MAC-based hash may be applied to packets by using the following methods.
On the E-Series, to change the 5-tuple default to 3-tuple, MAC, or packet-based, use the following
command in CONFIGURATION mode:
For details on the
load-balance command, see the IP Routing chapter of the FTOS Command Reference.

Command Syntax Command Mode Purpose
[no] load-balance [ip-selection
{3-tuple | packet-based}] [mac]
CONFIGURATION To designate a method to balance traffic over a port
channel. By default, IP 5-tuple is used to distribute
traffic over members port channel.
ip-selection 3-tuple—Distribute IP traffic based on IP
source address, IP destination address, and IP protocol type.
ip-selection packet-based—Distribute IPV4 traffic based
on the IP Identification field in the IPV4 header.
mac—Distribute traffic based on the MAC source address,
and the MAC destination address.
