思科路由器7

⑴ 思科 路由器的详解

CDP CISCO discovery protocol CISCO发现协议
并不是说能登陆邻居 而是如果邻居是CISCO的设备 可以查看信息
如型号内,端口等信息
一般在#下打 sh cdp neighbor 就可以显容示邻居信息
1721#sh cdp nei
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
S - Switch, H - Host, I - IGMP, r - Repeater

Device ID Local Intrfce Holdtme Capability Platform Port ID
Switch Fas 0 161 S I WS-C2950-2Fas 0/1

全局下 cdp run/no cdp run 可以开启CDP 或关闭
接口下 cdp enable /no cdp enable可以控制CDP包在接口上的发送

⑵ 思科路由器系列型号有什么区别

思科路由器系列他们的区抄别是： 从思科产品介绍上来看，2900系列是面向中小企业的路由器，7200系列是面向运营商级别的路由器， 但是价格上来看，一般2900系列的都在1W多，7200系列最低的才7000多，2系列是低端的，7系列是高端的，背板转换速率高，模块化的，可根据需要添加模块。 2比作象赛扬的PC, 7就是多路志强的服务器。 10年前单位用过2600系列，还有台5500还是7500记不得了，高端的那台背后有13个插槽，可更换模块。

⑶ 思科路由器配置

按你题目，F0口的子网是26位，即是192.168.7.193是属于192.168.7.192-255这个网段的。而S0的子网是27位，即是内192.168.7.226是属于192.168.7.224-255这个段，而226也刚容好是属于F0那个段，路由器上是不允许同时有两个端口属于同一个网段的，所以提示：“overlaps”

⑷ 如何设置思科无线路由器

思科路由器设置方法如下：

1.首先，我们需要将我们的思科路由器和光猫用 网线 连接好，连接的顺序是 电话线 、光猫、路由器以及电脑，如果没有绑定电话的可以不用连接电话线。将连接路由器的网线插到光猫的WAN插口上，其他的四个插口是用来插网线连接电脑的。

3.接下来，打开我们电脑中的ie浏览器，输入思科路由器的登陆地址，大部分都是192.168.1.1，我们可以通过查看路由器底部的铭牌上面的标注来确认一下思科路由器的登陆地址。

4.这时，会弹出一个新的界面，在弹出的界面中，分别在用户名和密码两栏中输入帐号和密码，账号和密码默认都是admin，确认进入。

5.进入之后，我们需要在思科路由器的设置界面中找到左边的网络配置，然后点击进入。

6..选择下拉栏里的外网设置，选择PPPoE拨号模式，在输入帐号密码的地方输入宽带上网帐号和密码。设置完成后，记得点击保存哦。

7.选择内网设置，有些时候界面也可能叫LAN口设置，设置LAN口网IP，一般使用路由器默认的即可，设置完成后，也要点击保存。

8.选择DHCP服务，选择开启DHCP，指定DHCP自动分配IP地址范围，设置完成后，点击保存。如果是 无线路由 器的话，还需要进入无 线管 理中，将无线开启，然后进行对自己无线网络用户名和密码的设置。

⑸ 思科路由器

如果用静态路由，按你的要求，PC2回到PC0和PC1回到PC0是不同的路径，那么问题来了，在R1和R2上就专会出现两个属到PC0的路径，该往那边走呢？所以静态路由无法实现

如果用ospf，那么你势必需要规划R0、R1、R2三个路由互联的cost值，你根本无法规划
如果用eigrp，你需要规划度量值，你这里也不能规划

综上，R2和R1都有两条路径到PC0，路由一定会乱

所以，你这里要想达到要求，那么R0上必须做nat，这样R1和R2可以没有指向R0的路由，那么就可以用策略路由实现PC0从R0经过R1-R2到PC2，PC0从R0经过R2-R1-R3到PC1，但是你PC1和PC2就不能够访问PC0了

⑹ 怎么进入思科路由器的配置

1、打开Cisco Packet Tracer模拟器。

⑺ 思科7200路由器multichannel怎么配置

1.Controller Configuration Examples控制器配置举例
The following example shows a typical controller configuration for
the multichannel E1/PRI port adapter on a Cisco 7200 series or
Cisco uBR7200 series router:
router> enable
router# configure terminal
router(config)# controller E1 1/0
router(config-controller)# framing crc4
router(config-controller)# linecode hdb3
router(config-controller)# clocksource internal
router(config-controller)# channel-group 0 timeslots 1-31
router(config-controller)# description ppp channel 5
router(config-controller)# shutdown
router(config-controller)# ^Z
2.Interface Configuration Examples接口配置举例
The following example shows a typical interface configuration for
the multichannel E1/PRI port adapter on a Cisco 7200 series or
Cisco uBR7200 series router:
router> enable
router# configure terminal
router(config)# interface serial
router(config)# interface serial 4/1:0
router(config-if)# encapsulation ppp
router(config-if)# description ppp channel 5
router(config-if)# no shutdown
router(config-if)# ^Z
3. Configuring Multichannel E1 Interfaces 配制多通道E1接口
The channel groups must be mapped before the multichannel E1/PRI
controller can be configured. The following are controller commands
used to map the channel group (the default variable is listed first):
controller E1 port-adapter-slot number/port-number (for Cisco 7200
series router)
clock source [line | internal]
linecode [ami | hdb3]
framing [crc4 | no-crc4]
loopback [diagnostic | local {payload | line}]
shutdown
channel-group number timeslots list
Number is the channel group 0 to 30.
list is a number between 1 and 31. You can enter timeslots indivially
and separate them by commas, or enter them as a range separated by
a hyphen (for example, 1-3, 8, 9-18). Timeslot 0 is an illegal
configuration.

⑻ 如何在Win7下通过console登录思科的路由器

1、首先用console线缆，将电脑连接到路由器的Console口。

⑼ 思科路由器wrt54gver.7原密码查询

路由器的账户和密码一般都是：admin（也有是：guest 、 root ）

或者可以查看说明书和路由器底部都有内提示。比容如IP地址：192.168.1.1

如果在路由器设置界面改了之后，又忘了，可以点击重置路由器按钮，就会恢复到原始密码。

无线密码和路由器登录密码是两回事。
