Lab小技巧: Banner設定(三)

相關文章： Lab小技巧

在各位貼上後, 先登出, 再重新登入, 就可以看到其中的三種 Banner, 如下圖所示:

Press RETURN to get started.

01 MOTD banner
02

01 LOGIN banner
02

User Access Verification

Password:
01 EXEC banner
02

RouterA>

其實Banner有很多種類, 我們可以使用以下的例子, 剪貼到全域的設定區(Global Configuration Mode), 來作一一檢視(下載原始檔):

banner exec /
01 EXEC banner
02
/

banner incoming /
01 INCOMING banner
02
/

banner login /
01 LOGIN banner
02
/

banner motd /
01 MOTD banner

/

banner prompt-timeout /
01 Prompt-Timeout banner

Lab小技巧: Banner設定(一)

相關文章： Lab小技巧

Banner是在登入IOS的操作介面時, 額外顯示出來的文字訊息, 可以用來提醒登入的操作員, 重要的注意事項.

以MOTD(Message of the Day) Banner為例, 我們可以用以下的方式去設定.

RouterA#conf t
Enter configuration commands, one per line. End with CNTL/Z.
RouterA(config)#banner motd /
Enter TEXT message. End with the character '/'.
Message of the Day, Good Day!
Welcome to RouterA/
RouterA(config)#end
RouterA#

這時候再重新登入, 就可以看到剛才作的Banner設定文字了!

RouterA#logout

Press RETURN to get started.

Message of the Day, Good Day!
Welcome to RouterA

Lab小技巧: 避免拼錯字, 而卡在命令執行介面

相關文章： Lab小技巧

使用命令執行介面操作IOS時, 常常因為拼錯字, 結果IOS自動試著解析這個拼錯的名稱, 浪費了不少時間, 又無法中斷, 像以下這樣:

Translating "pqr"...domain server (255.255.255.255)
(255.255.255.255)

其實只要取消這個自動解析的功能就可以了:

Router(config)# no ip domain-lookup

那如果已經卡在裡面的話, 又要如何解救?

其實最好的辦法, 還是等他自己Timeout. 大約要30秒.
再不然, 用 "Ctrl-Shift-6 x", 穩穩地按, 不要按太快, 也不要按 Enter. 也許可以少個幾秒鐘!

使用乙太網路線, 何時用Straight ? 何時用Cross Over?

我們先將網路設備分成兩大陣營:

主機: 包括路由器, PC, 伺服器. 上面安裝的網路卡, 都是給自己使用的.
基礎建設: 包括集線器, 交換器, 核心交換器. 上面的安裝的網路卡, 都是給別人用的.

如果是不同陣營的設備互接, 就用 Straight;
如果是相同陣營的設備互接, 就用 Cross Over.

IPv6 可以定義多少位址?

相關文章： CCNA, CCNA Exploration 4.0, Cisco 網路學院, IPv6

精準一點說, 應該是以現在的65億人口來算, 每人可以分得到大約 5×10²⁸ 個IP位址. 這也算是天文數字了!
http://en.wikipedia.org/wiki/IPv6

另外在 Google 找到一則有趣的分析評論, 其中一段的大意是 "IPv6位址有地球本身的總質子數那麼多" 或是 "IPv6位址有全宇宙的分子數那麼多" 的宣稱的確是誇大了.

Frame Relay 四個重要推動者

Frame Relay的"四個重要推動者"應該是 Cisco, Digital Equipment Corporation (DEC), Northern Telecom, and StrataCom. 隨後在 1991年 Frame Relay Forum就成立了.

....
A major development in Frame Relay's history occurred in 1990 when Cisco, Digital Equipment Corporation (DEC), Northern Telecom, and StrataCom formed a consortium to focus on Frame Relay technology development.

%Warning: portfast should only be enabled on ports connected to a single host.
Connecting hubs, concentrators, switches,  bridges, etc.to this interface
when portfast is enabled, can cause temporary spanning tree loops.
Use with CAUTION

%Portfast has been configured on FastEthernet0/2 but will only
have effect when the interface is in a non-trunking mode.
