H3C交换机如何看端口的速率

display interface可以看到：

<Sysname> display interface ten-gigabitethernet 1/0/1

Ten-GigabitEthernet1/0/1

Current state: Administratively DOWN

Line protocol state: DOWN

Description: Ten-GigabitEthernet1/0/1 Interface

Bandwidth: 1000000 kbps

Maximum transmission unit: 1500

Allow jumbo frames to pass

Broadcast max-ratio: 100%

Multicast max-ratio: 100%

Unicast max-ratio: 100%

Internet protocol processing: Disabled

IP packet frame type: Ethernet II, hardware address: 3822-d666-bd0c

IPv6 packet frame type: Ethernet II, hardware address: 3822-d666-bd0c

Loopback is not set

Media type is twisted pair, port hardware type is 10G_BASE_T

Port priority: 2

Unknown-speed mode, unknown-duplex mode

Link speed type is autonegotiation, link duplex type is autonegotiation

Flow-control is not enabled

The maximum frame length is 10000

Last link flapping: 6 hours 39 minutes 28 seconds

Last clearing of counters: Never

可使用以下查看端口协商速率：

display interface brief

 Speed一列代表协商速率  Duplex一列代表双工模式（A为自动协商、F为全双工、H为半双工）

可使用以下查看实时流量：
display counters rate inbound interface（入方向）
display counters rate outbound interface （出方向）
在Usage一列查看端口利用率，判断端口出入流量。
