锐捷交换机常用配置命令
一、交换机配置模式介绍交换机配置模式主要有：用户模式：此模式只可以简单的查看一些交换机的配置和一些简单的修改。
Switch>特权模式：此模式可以查看一些交换机的配置，后面讲述的很多show命令便是在此模式下进行的，还可以对一些简单的设置配置，例如时间。
Switch> enable 1F1000M2126G50G2150G2150G2150G800.073c800.073c800.073c800.073c800.073c2126G0.0.00.0.01.1.10.0.00.0.0S* 0.0.0Switch#S代表是静态路由，C代表是直连路由。
三、交换机常用查看命令show cpu //查看CPU利用率switch #show cpuCPU utilization for five seconds: 3%CPU utilization for one minute : 6%CPU utilization for five minutes: 6%如果CPU利用率偏高，就要考虑网络中是否有攻击或者网络设备是否能胜任当前的网络负载。
一般来说，CPU超过30%就不正常了。
show clock //查看交换机时钟switch #show clockSystem clock : 2007-3-18 10:29:14 Sundayshow logging //查看交换机日志switch #show loggingSyslog logging: EnabledConsole logging: Enabled(debugging)Monitor logging: DisabledBuffer logging: Enabled(debugging)Server logging severity: debuggingFile logging: Disabled注意，日志前面都有时间，但交换机的时钟往往和生活中的时钟对不上，这时需要我们使用show clock 查看交换机时钟，进而推断日志发生的时间，便于发现问题。
交换机常用操作指令华为
华为交换机常用指令一、交换机设备登陆及配置：1、设备登陆配置我中心维护汇聚和热点交换机，交换机类型为5300、2300和GPON，交换机使用secure CRT软件登录。
交换机使用之前需要刷机，使用secureCRT配置：协议是serial，端口com12，波特流9600，流控制不配置。
刷交换机所需要的信息：在3a模式下用户名和密码；snmp为网络管理协议，配置网管所需的指令，固定不变； telnet配置——远程登陆配置信息。
登陆汇聚和热点交换机首先93-5交换机（核心交换机），登录协议选择ssh登录，登陆其它交换机在93-5上使用telnet（远程登陆）命令跳转，只能单向。
核心交换机登陆用户名：hanxu69309，密码：Hx#9309。
华为汇聚和热点交换机的登陆用户名和密码都为huaweitest。
其他核心交换机的登录地址：（交换机型号为9312）（交换机型号为6500）（交换机型号为6500）（交换机型号为8500）（交换机型号为8500）（交换机型号为9306）2、交换机配置思路：➢配置设备名称。
➢管理AP所需要配置的信息➢管理交换机配置的信息➢在3a模式下配置，配置以下用户名和密码。
（配置固定）➢snmp为网络管理协议，下面为加入网管所配置的指令，固定不变。
➢telnet配置——远程登陆配置信息3、数据准备：➢管理VLAN的ID。
➢交换机的管理IP。
➢交换机连接其他交换机的接口号。
➢验证方式、用户名和密码。
二、5300交换机开站指令1、交换机简介5300系列交换机，包括5328和5324等，不能给AP供电。
下面介绍的指令为5328，是5300系列的一种，共有28个端口。
532853242、开站指令➢配置设备名称。
System //进入配置模式sysname SDJN-WLAN-SW-ZRSJGC-1-S5328 //给交换机命名vlan 1 2001 2101 2126 to 2127 2218 2501 //创建vlanbpdu-tunnel reserved03 group-mac 0100-5e99-9999 //交换机支持sim认证使用，网维提供的。
DELL交换机常用命令
DELL交换机常用基本命令登陆方式：超级终端-com1-还原默认值创建一个新VLAN：vlan2console>console> enconsole# configureconsole(config)# vlan databaseconsole(config-vlan)# vlan 2console(config-vlan)# exit把该交换机的1到10端口加入新创建的vlan 2中console(config)# interface range ethernet g(1-10)console(config-if)# switchport mode accessconsole(config-if)# switchport access vlan 2console(config-if)# exit创建一个端口汇聚组：ID是10，把该交换机的21到24口捆绑到一起做级联用console>console> enconsole# configureconsole(config)# interface range ethernet g(21-24)console(config-if)# channel-group 10 mode onconsole(config-if)# exit如果是IPSAN网络，做如下操作对交换机进行优化：console#console# configureconsole(config)# interface range Ethernet g（1-24）console(config-if)# spaningtree portfast onconsole(config-if)# exitconsole(config)# iscsi enableconsole(config)# iscsi cos remark dscp 7console(config)# iscsi aging-time 1000console(config)# end如果要升级交换机firmware，为该交换机设定一个最高级权限的用户名和密码，然后通过web界面访问改交换机，设定用户名和密码操作如下：console# configureconsole(config)# username admin password password level 15console(config)# exit更改交换机IP地址：console# configureconsole(config) ipaddress 192.168.100.123 255.255.255.0保存配置：console# copy running-config startup-configconsole# yes以上就是DELL交换机的一些基本命令，大体上跟CISCO差不多，个别命令略有区别，希望能给大家提供一点帮助。

交换机管理性IP地址配置
CISCO及H3C交换机设置管理性IP地址试验拓扑图：分析：为什么跨网段交换机之间管理需要设置默认网关呢？在交换机中可以给vlan 1配置一个IP地址，即为交换机的管理性IP，使用配置的管理性IP地址可以让网络管理员使用telnet或网络管理软件等方式远程的来管理该交换机；例如：可以在交换机上做如下配置Switch01# conf tSwitch01(config) # interface vlan 1Switch01(config-if)# no shutSwitch01(config-if)# ip address 192.168.0.253Switch01(config)#enable password 123abc!在交换机所在网段内的工作站pc-01可以使用telnet方式远程管理该交换机telnet 192.168.0.253如果现在用户登录到switch-01中，想利用网络远程管理另一个网段的交换机switch-02就需要在双方交换机设置一个默认网管，表示交换机无法转发的数据帧就交给该IP地址（网关IP地址）的设备处理以便能完成数据帧的转发过程；发送的过程如下图：例如：可以在交换机上做如下配置：Switch02#conf tSwitch03(config)#ip default-gateway 192.168.0.254 （给交换机设置默认网关命令）在工作站pc-01可以使用telnet方式远程管理不同网段的交换机telnet 192.168.1.253总结：一般来说对于同网段的交换机管理时对交换机配置一个管理性IP地址就可以了，当要从一个交换机跨网段管理另一个交换机时需要给交换机配置默认网管补充说明：交换机的VLAN虚接口承载在物理端口之上，即某VLAN所包含的物理端口UP之后，该VLAN虚接口才会UP.对于三层交换机，可以为多个VLAN接口配置IP地址，而且默认情况下各个VLAN接口之间可以访问；对于二层交换机来说，为VLAN接口配置的IP地址只能用于管理华为交换机：在华为的设备中，默认的管理VLAN是VLAN1.在二层交换机中，只允许一个管理VLAN的存在。
