Configuring A Load Balancing Policy - Huawei quidway s7700 Configuration Manual

Quidway S7700 Smart Routing Switch
Configuration Guide - SPU
By default, the SPU does not respond to ping requests of users.
Step 6 (Optional) Run:
parameter connection profile-name
A connection parameter profile is bound to the Layer 3 classifier.
A connection parameter profile can be bound to one or more Layer 3 classifiers.
By default, no connection parameter profile is bound to a Layer 3 classifier.
Step 7 (Optional) Run:
nat outbound address-group number [ no-pat ]
An NAT address pool is bound to the Layer 3 classifier.
no-pat indicates that PAT is not performed. That is, only the source IP address of packets is
translated through NAT. The source port number, however, is not translated.
An NAT address pool takes effect only after being bound to a Layer 3 classifier or a link instance.
If an NAT address pool is bound to a Layer 3 classifier and a link instance, the NAT address
pool bound to the link instance takes effect.
An NAT address pool can be bound to multiple Layer 3 classifiers, whereas the same interface
processing mode must be used. That is, if an NAT address pool is bound to a Layer 3 classifier
in no-pat mode, other Layer 3 classifiers must be bound to the NAT address pool in no-pat
mode rather than in pat mode.
By default, no NAT address pool is bound to a Layer 3 classifier.

6.3.11 Configuring a Load Balancing Policy

This section describes how to create a load balancing policy, and bind the Layer 3 classifier to
the load balancing policy.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
load-balance policy policy-name
A load balancing policy is created and the load balancing policy view is displayed.
Up to 1024 load balancing policies can be created.
By default, no load balancing policy is configured.

NOTE
l If the SPU is required to respond to ping requests of users, ping request packets of users must match
the ACL in the Layer 3 classifier.
l If the ACL in the Layer 3 classifier for matching the source and destination IP addresses is set to
any, the SPU responds to any ping request of users. In this case, the ACL is invalid. Therefore, you
need to configure the ACL in a Layer 3 classifier with caution.
