思科路由器7
⑴ 思科 路由器的詳解
CDP CISCO discovery protocol CISCO發現協議
並不是說能登陸鄰居 而是如果鄰居是CISCO的設備 可以查看信息
如型號內,埠等信息
一般在#下打 sh cdp neighbor 就可以顯容示鄰居信息
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 可以開啟CDP 或關閉
介面下 cdp enable /no cdp enable可以控制CDP包在介面上的發送
⑵ 思科路由器系列型號有什麼區別
思科路由器系列他們的區抄別是: 從思科產品介紹上來看,2900系列是面向中小企業的路由器,7200系列是面向運營商級別的路由器, 但是價格上來看,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,背板轉換速率高,模塊化的,可根據需要添加模塊。 2比作象賽揚的PC, 7就是多路志強的伺服器。 10年前單位用過2600系列,還有台5500還是7500記不得了,高端的那台背後有13個插槽,可更換模塊。
⑶ 思科路由器配置
按你題目,F0口的子網是26位,即是192.168.7.193是屬於192.168.7.192-255這個網段的。而S0的子網是27位,即是內192.168.7.226是屬於192.168.7.224-255這個段,而226也剛容好是屬於F0那個段,路由器上是不允許同時有兩個埠屬於同一個網段的,所以提示:「overlaps」
⑷ 如何設置思科無線路由器
思科路由器設置方法如下:
1.首先,我們需要將我們的思科路由器和光貓用 網線 連接好,連接的順序是 電話線 、光貓、路由器以及電腦,如果沒有綁定電話的可以不用連接電話線。將連接路由器的網線插到光貓的WAN插口上,其他的四個插口是用來插網線連接電腦的。
3.接下來,打開我們電腦中的ie瀏覽器,輸入思科路由器的登陸地址,大部分都是192.168.1.1,我們可以通過查看路由器底部的銘牌上面的標注來確認一下思科路由器的登陸地址。
4.這時,會彈出一個新的界面,在彈出的界面中,分別在用戶名和密碼兩欄中輸入帳號和密碼,賬號和密碼默認都是admin,確認進入。
5.進入之後,我們需要在思科路由器的設置界面中找到左邊的網路配置,然後點擊進入。
6..選擇下拉欄里的外網設置,選擇PPPoE撥號模式,在輸入帳號密碼的地方輸入寬頻上網帳號和密碼。設置完成後,記得點擊保存哦。
7.選擇內網設置,有些時候界面也可能叫LAN口設置,設置LAN口網IP,一般使用路由器默認的即可,設置完成後,也要點擊保存。
8.選擇DHCP服務,選擇開啟DHCP,指定DHCP自動分配IP地址范圍,設置完成後,點擊保存。如果是 無線路由 器的話,還需要進入無 線管 理中,將無線開啟,然後進行對自己無線網路用戶名和密碼的設置。
⑸ 思科路由器
如果用靜態路由,按你的要求,PC2回到PC0和PC1回到PC0是不同的路徑,那麼問題來了,在R1和R2上就專會出現兩個屬到PC0的路徑,該往那邊走呢?所以靜態路由無法實現
如果用ospf,那麼你勢必需要規劃R0、R1、R2三個路由互聯的cost值,你根本無法規劃
如果用eigrp,你需要規劃度量值,你這里也不能規劃
綜上,R2和R1都有兩條路徑到PC0,路由一定會亂
所以,你這里要想達到要求,那麼R0上必須做nat,這樣R1和R2可以沒有指向R0的路由,那麼就可以用策略路由實現PC0從R0經過R1-R2到PC2,PC0從R0經過R2-R1-R3到PC1,但是你PC1和PC2就不能夠訪問PC0了
⑹ 怎麼進入思科路由器的配置
1、打開Cisco Packet Tracer模擬器。
⑺ 思科7200路由器multichannel怎麼配置
1.Controller Configuration Examples控制器配置舉例
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介面配置舉例
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 配製多通道E1介面
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下通過console登錄思科的路由器
1、首先用console線纜,將電腦連接到路由器的Console口。
⑼ 思科路由器wrt54gver.7原密碼查詢
路由器的賬戶和密碼一般都是:admin(也有是:guest 、 root )
或者可以查看說明書和路由器底部都有內提示。比容如IP地址:192.168.1.1
如果在路由器設置界面改了之後,又忘了,可以點擊重置路由器按鈕,就會恢復到原始密碼。
無線密碼和路由器登錄密碼是兩回事。
