需要把接口优先级修改一下

1.1  适用的产品系列

本案例适用于软件平台为Comware V7系列防火墙：F100-X-G2、F1000-X-G2、F100-X-WiNet、F1000-AK、F10X0等。

1.2  配置需求及实现的效果

防火墙A与防火墙B堆叠后使用透明模式部署在核心交换机与汇聚交换机之间，需要使用目前情况下所有流量通过防火墙A进行转发，如果防火墙A出现宕机再由防火墙B接管所有业务、当防火墙A故障恢复后再次接管所有业务。

2.2.6  安全策略配置

防火墙目前版本存在两套安全策略，请在放通安全策略前确认设备运行那种类型的安全策略？以下配置任选其一。

1. 通过命令“display cu | in security-policy”如果查到命令行存在“security-policy disable”或者没有查到任何信息，则使用下面策略配置。

[H3C]display cu | in security-policy

 security-policy disable

#创建对象策略pass。

[H3C]object-policy ip pass

[H3C-object-policy-ip-pass] rule 0 pass

[H3C-object-policy-ip-pass]quit

#创建Trust到Untrust域的域间策略调用pass策略。

[H3C]zone-pair security source Trust destination local

[H3C-zone-pair-security-Trust- local]object-policy apply ip pass

[H3C-zone-pair-security-Trust- local]quit

[H3C]zone-pair security source local destination Trust

[H3C-zone-pair-security-local -trust]object-policy apply ip pass

[H3C-zone-pair-security-local -trust]quit

[H3C]zone-pair security source Untrust destination local

[H3C-zone-pair-security-Untrust- local]object-policy apply ip pass

[H3C-zone-pair-security-Untrust- local]quit

[H3C]zone-pair security source local destination Untrust

[H3C-zone-pair-security-local -Untrust]object-policy apply ip pass

[H3C-zone-pair-security-local -Untrust]quit

[H3C]zone-pair security source Trust destination Untrust

[H3C-zone-pair-security-Trust -Untrust]object-policy apply ip pass

[H3C-zone-pair-security-Trust -Untrust]quit

2. 通过命令“display cu | in security-policy”如果查到命令行存在“security-policy ip”并且没有查到“security-policy disable”，则使用下面策略配置。

[H3C]display cu | in security-policy

security-policy ip

创建安全策略并放通local到trust和trust到local的安全策略。

[H3C]security-policy ip

[H3C-security-policy-ip]rule 10 name test

[H3C-security-policy-ip-10-test]action pass

[H3C-security-policy-ip-10-test]source-zone local

[H3C-security-policy-ip-10-test]source-zone Trust

[H3C-security-policy-ip-10-test]source-zone Untrust

[H3C-security-policy-ip-10-test]destination-zone local

[H3C-security-policy-ip-10-test]destination-zone Trust

[H3C-security-policy-ip-10-test]destination-zone Untrust

[H3C-security-policy-ip-10-test]quit

2.3  汇聚交换机配置

#创建三层聚合接口并设置IP地址。

3.1.3  注意事项

1、配置冗余组后，所有加入冗余组的物理接口状态必须处于UP状态，否则会造成冗余组主备切换异常。
