ipv4 field
Function
The ipv4 field command configures a load balancing mode of IPv4 packets in a load balancing profile.
The undo ipv4 field command deletes a load balancing mode of IPv4 packets or restores the default load balancing mode of IPv4 packets.
By default, load balancing of IPv4 packets is based on the source IP address (sip) and destination IP address (dip).
Only the S5720-EI, S5720-HI, S5730-HI, S5730S-EI, S5730-SI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720-LI, S6720S-EI, S6720S-LI, S6720S-SI, S6720-SI, S6730-H, S6730S-H, S6730-S, and S6730S-S support this command.
Format
ipv4 field [ dip | l4-dport | l4-sport | protocol | sip | sport | vlan ] *
undo ipv4 field [ dip | l4-dport | l4-sport | protocol | sip | sport | vlan ] *
Only dip, sip, and sport are supported on the S5730-SI, S5730S-EI, S6720-LI, S6720S-LI, S6720-SI, and S6720S-SI.
Parameters
Parameter |
Description |
Value |
|---|---|---|
dip |
Performs load balancing based on destination IP addresses in IPv4 packets. |
- |
l4-dport |
Performs load balancing based on transport-layer destination port numbers in IPv4 packets. |
- |
l4-sport |
Performs load balancing based on transport-layer source port numbers in IPv4 packets. |
- |
protocol |
Performs load balancing based on protocol types in IPv4 packets. |
- |
sip |
Performs load balancing based on source IP addresses in IPv4 packets. |
- |
sport |
Performs load balancing based on physical-layer source port numbers in IPv4 packets. |
- |
vlan |
Performs load balancing based on VLAN IDs in IPv4 packets. |

Usage Guidelines
Usage Scenario
The undo ipv4 field command with no parameter specified restores the default load balancing mode of IPv4 packets. The undo ipv4 field command with a parameter specified deletes a specified load balancing mode of IPv4 packets.
Precautions
If you run the ipv4 field command multiple times, only the latest configuration takes effect.
On the S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-HI, S6730-H, S6730S-H, S6730-S, and S6730S-S switches, if l4-dport or l4-sport is specified for L2TP packets, load balancing is performed based on session id and tunnel id in L2TP packets rather than l4-dport and l4-sport.
Example
# In the load balancing profile a, set the load balancing mode of IPv4 packets to sip and protocol, that is, load balancing based on source IP addresses and protocol types of IPv4 packets.
