nicinfo

在QNX操作系统中，nicinfo是一个用于显示网络接口卡（NIC）信息的命令行工具。它可以提供有关系统中所有可用网络接口卡的详细信息，例如接口名称、MAC地址、IP地址、掩码、广播地址、传输单元大小等等。

通过nicinfo命令可以查看所有网络接口卡的信息，也可以通过添加接口名称参数来查看特定接口的信息。

nicinfo命令对于调试和排除与网络有关的问题非常有用，也可以用于监视和管理系统中的网络接口卡

ifmcstat

ifmcstat是一个命令行程序，用于监控和显示网络接口的统计信息。使用ifmcstat，可以查看网络接口的包传输数量、丢包数量、传输速率等详细信息。下面是使用ifmcstat的示例命令：

./ifmcstat eht0
lo0:inet6 ::1inet6 fe80::1%lo0group ff01:1::1 refcnt 2group ff02::1%lo0 refcnt 2group ff02::1:ff00:1%lo0 refcnt 2
eth0:inet6 fe80::6c3:e6ff:fe4f:0%eth0group ff01:11::1 refcnt 1group ff02::1%eth0 refcnt 1group ff02::1:ff4f:0%eth0 refcnt 1enaddr 04:c3:e6:4f:00:00 multicnt 301:00:5e:00:00:01 -- 01:00:5e:00:00:01 133:33:00:00:00:01 -- 33:33:00:00:00:01 233:33:ff:4f:00:00 -- 33:33:ff:4f:00:00 1

上述命令将显示eth0网络接口的数据传输统计信息。
