问下16k查看当前接口流量使用情况用什么命令呢？ 包括子接口也需要查看。

您好，参考

display interface g1/0/X里面可以查看接口的最近五分钟的流量情况

1.1.10  display interface

display interface命令用来显示接口的运行状态和相关信息。

【命令】

display interface [ interface-type [ interface-number ] ] [ brief [ description | down ] ]

【视图】

任意视图

【缺省用户角色】

network-admin

network-operator

【参数】

interface-type：指定接口类型。

interface-number：指定接口编号。

brief：显示接口的概要信息。不指定该参数时，将显示接口的详细信息。

description：用来显示用户配置的接口的全部描述信息。如果某接口的描述信息超过27个字符，不指定该参数时，只显示描述信息中的前27个字符，超出部分不显示。

down：显示当前物理状态为down的接口的信息以及down的原因。不指定该参数时，将不会根据接口物理状态来过滤显示信息。

【使用指导】

如果不指定接口类型和接口编号，则显示所有接口的信息。

如果仅指定接口类型，则显示所有该类型接口的信息。

【举例】

# 查看二层以太网接口GigabitEthernet1/0/1的运行状态和相关信息。
