想看一下8樓交換機(jī)所有端口的狀態(tài)，因?yàn)橛袃膳_(tái)嘛，不確定是哪臺(tái)，一臺(tái)插得網(wǎng)口多，一臺(tái)插得少。交換機(jī)是H3C的，以前在思科的交換機(jī)上有個(gè)很好用的命令：show ip in br ，H3C應(yīng)該是 dis ip in br，發(fā)現(xiàn)不行，就只出現(xiàn)了VLAN信息，沒(méi)有端口信息。

原來(lái)H3C下應(yīng)該是 dis in br，但顯示出來(lái)的也不對(duì)啊！后來(lái)發(fā)現(xiàn)是后面的“br”不對(duì)，這個(gè)應(yīng)該補(bǔ)全為：brief，不然它是：Bridge-Aggregation，所以不對(duì)嘛！執(zhí)行效果如下：

dis interface brief

The brief information of interface(s) under route mode:

Link: ADM – administratively down; Stby – standby

Protocol: (s) – spoofing

Interface Link Protocol Main IP Description

M-GE0/0/0 DOWN DOWN –

NULL0 UP UP(s) –

Vlan1 DOWN DOWN –

Vlan2000 UP UP 172.16.1.45

The brief information of interface(s) under bridge mode:

Link: ADM – administratively down; Stby – standby

Speed or Duplex: (a)/A – auto; H – half; F – full

Type: A – access; T – trunk; H – hybrid

Interface Link Speed Duplex Type PVID Description

BAGG6 DOWN auto A T 1

GE1/0/1 DOWN auto A A 801

GE1/0/2 UP 1G(a) F(a) A 801

GE1/0/3 UP 1G(a) F(a) A 801

GE1/0/4 DOWN auto A A 801

GE1/0/5 UP 100M(a) F(a) A 801

GE1/0/6 UP 10M(a) F(a) A 801

GE1/0/7 DOWN auto A A 801

GE1/0/8 DOWN auto A A 801

GE1/0/9 DOWN auto A A 801

GE1/0/10 DOWN auto A A 801

GE1/0/11 DOWN auto A A 801

GE1/0/12 DOWN auto A A 801

GE1/0/13 DOWN auto A A 801

GE1/0/14 DOWN auto A A 801

GE1/0/15 UP 100M(a) F(a) A 801

GE1/0/16 UP 1G(a) F(a) A 801

GE1/0/17 UP 1G(a) F(a) A 801

GE1/0/18 DOWN auto A A 801

GE1/0/19 DOWN auto A A 801

GE1/0/20 DOWN auto A A 801

后來(lái)我發(fā)現(xiàn)還有個(gè)命令也可以查看所有的端口狀態(tài)：dis port-security。顯示如下：

dis port-security

Equipment port-security is disabled

Trap is disabled

AutoLearn aging time is 0 minutes

Disableport Timeout: 20s

OUI value:

GigabitEthernet1/0/1 is link-down

GigabitEthernet1/0/2 is link-up

GigabitEthernet1/0/3 is link-up

GigabitEthernet1/0/4 is link-down

GigabitEthernet1/0/5 is link-up

GigabitEthernet1/0/6 is link-up

GigabitEthernet1/0/7 is link-down

GigabitEthernet1/0/8 is link-down

GigabitEthernet1/0/9 is link-down

GigabitEthernet1/0/10 is link-down

GigabitEthernet1/0/11 is link-down

GigabitEthernet1/0/12 is link-down

GigabitEthernet1/0/13 is link-down

GigabitEthernet1/0/14 is link-down

GigabitEthernet1/0/15 is link-up

GigabitEthernet1/0/16 is link-up

GigabitEthernet1/0/17 is link-up

GigabitEthernet1/0/18 is link-down

GigabitEthernet1/0/19 is link-down

GigabitEthernet1/0/20 is link-down

以下為網(wǎng)絡(luò)轉(zhuǎn)載：

大家都知道交換機(jī)的端口都是比較多，當(dāng)你想查看某些端口狀態(tài)(是處于UP還是DOWN狀態(tài))時(shí)，通常我們會(huì)使用以下命令：

思科：show interface X

H3C：display interface X

注：X表代端口號(hào)，如e1/0/1之類的。

但如果當(dāng)交換機(jī)的端口非常多時(shí)，而且你想知道所有端口的狀態(tài)時(shí)，你再一條一條命令輸進(jìn)去，那是相當(dāng)累人的，同時(shí)輸出的結(jié)果也過(guò)于詳細(xì)，看得人眼花繚亂。

如何有效的查看所有端口的狀態(tài)呢？我們可以使用以下命令：

思科：show ip interface brief

H3C：display interface brief

華為的交換機(jī)好像沒(méi)有什么命令能實(shí)現(xiàn)這種功能。

總結(jié)
