## 命令功能
ping6用于测试IPv6网络连接是否正常。
## 命令格式
ping6 _\[-c count\] \[-I interface / sourceAddress\] destination_
## 参数说明
**表 1** 参数说明
参数
|
参数说明
|
取值范围
|
|---|
-c count
|
执行的次数，不带本参数则默认为4次。
|
1~65535
|
-I interface
|
指定网卡执行IPv6 ping操作。
|
N/A
|
-I sourceAddress
|
指定源IPv6地址执行ping操作。
|
N/A
|
destination
|
目标主机地址。
|
N/A
|
## 使用指南
- 如果目的IPv6地址不可达，会显示请求超时。
- 如果显示发送错误，说明没有到目的IPV6的路由。
- 命令需要启动TCP/IP协议栈后才能使用。
