unicast load-balance enhanced

Function

The unicast load-balance enhanced command configures a load balancing mode for known unicast packets based on the inner or outer IP address.

The undo unicast load-balance enhanced commands restores the default loading balancing mode for known unicast packets.

By default, load balancing for known unicast packets is based on the outer IP address.

Only 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 support this command.

Usage Guidelines

When configuring enhanced Eth-Trunk load balancing, you can run the unicast load-balance enhanced command to configure known unicast packets, such as GRE packets, to be load balanced based on the inner IP address, outer IP address, or both.

In IPv4 over GRE or IPv6 over GRE scenarios, if inner-ip is specified, known unicast packets are load balanced based on the inner source IP address, inner destination IP address, or both. Similarly, you can configure known unicast packets to be load balanced based on the outer source IP address, outer destination IP address, or both. Additionally, known unicast packets can be load balanced based on the inner and outer source IP addresses, inner and outer destination IP addresses, or both.
In Ethernet over GRE scenarios, if inner-ip is specified, known unicast packets are load balanced based on the inner source MAC address, inner destination MAC address, or both. If outer-ip is specified, known unicast packets are load balanced based on the outer source IP address, outer destination IP address, or both. If both inner-ip and outer-ip are specified, known unicast packets are load balanced based on the outer source IP address and inner source MAC address, outer destination IP address and inner destination MAC address, or both.
In PPPoE scenarios, if inner-ip is specified, known unicast packets are load balanced based on the inner source IP address, inner destination IP address, or both. If outer-ip is specified, known unicast packets are load balanced based on the outer source MAC address, outer destination MAC address, or both. If both inner-ip and outer-ip are specified, known unicast packets are load balanced based on the inner source IP address and outer source MAC address, inner destination IP address and outer destination MAC address, or both.
