问题1: 添加服务器的IP地址，不能为D类和E类的IPv4地址。
D类地址 前四位为1110，注意是位
1、不分网络地址和主机地址。
2、地址范围：224.0.0.1 --- 239.255.255.254
E类地址 前五位为11110，注意是位
1、不分网络地址和主机地址
2、地址范围：240.0.0.1 --- 255.255.255.254

问题2: 对于与设备不在同一网段的服务(简单理解即没有与之互通的SNIP)，此服务绑定的透传类型(-Transparent YES)的健康检查监视器 mon_tcp_llb，健康检查失败，提示信息为【Failure - Internal error: resource unavailable to send probe.】
