The Many Faces of Love(2006-05-27 02:10:00)
摘要：Love.. what is love? A lot of people shared their views to what Love really is, or at least what Love is in their eyes. Perhaps love is just an illusion. A strong illusion, especially for those who are searching for a purpose of life. Is love an answer? Love can be wonderful, special, complicated, a distress, a gift, a curse, a tragedy, and most of all, an experience.
Love is a mysterious and a complicated force. What do a person mean when they say they love someone? Love is many different things. Each of us have our own understanding of Love is, and most of the time we base our definitions from feelings and experiences. The book defines love in many ways. "It is a strong affection for another arising out of kinship or personal ties." It can be an affection and tenderness felt by lovers. Love is the object of attachment, devotion, or admiration.
Just when we thought we finally grasp what love is, somebody asks:
"Does anyone really know what "LOVE" mean? I believe I have......
A Good Heart to Lean on(2006-05-27 02:09:00)
摘要：When I was growing up, I was embarrassed to be seen with my father. He was severely crippled and very short, and when we would walk together, his hand on my arm for balance, people would stare. I would inwardly squirm at the unwanted attention. If he ever noticed or was bothered, he never let on.
It was difficult to coordinate our steps —— his halting, mine impatient —— and because of that, we didn't say much as we went along. But as we started out, he always said, "You set the pace. I will try to adjust to you. "
Our usual walk was to or from the subway, which was how he got to work. He went to work sick, and despite nasty weather. He almost never missed a day, and would make it to the office even if others could not. A matter of pride.
When snow or ice was on the ground, it was impossible for him to walk, even with help. At such times my sisters or I would pull him through the streets of Brooklyn, NY, on a child's sleigh to the subway entrance. Once there, he woul......

Angels are Always There 天使一直在你身边(2006-05-27 02:07:00)
摘要：
Surrounding you are angels,
They are there to guide your path,
If weakness overcomes you,
They'll give you strength if you will ask.
They are your protection
When life seems too hard to bear,
And though you feel alone at times,
The angels ... they are there.
Their faces may be hidden
And their voices you might not hear,
But they are ALWAYS with you,
Through your laughter or your tears.
They'll walk along beside you,
They'll guide your steps along the way,
They'll comfort you and hold you,
Protect you night and day.
They'll hold to your hand tightly,
They'll not ever let it go,
And they'll gently lead you forward,
Taking each step very slow.
For even as you slumber,
They watch closely over you;
They are there beside you
In each and every thing you do.
When life is overwhelming,
And your spirit has grown tired,
Know they'll be there for you,
To uplift and to inspire.
And when you're torn and lonely,
And you see no hope a......
Weakness or Strength 将弱项变为强项(2006-05-27 02:07:00)
摘要：
Sometimes our biggest weakness can become your biggest strength. Take, for example, the story t of one 10-year-old boy who decided to study judo despite the fact that the had lost his left arm in a devastating car accident.
The boy began lesson with an old Japanese judo master. The boy was dong well, so he couldn't understand why, after three months of training, the master had taught him only one move.
"Mister," the boy finally said, "shouldn't I be learning more moves?"
"This is the only move you know, but this is the only move you'll ever need to know," the master replied.
Not quite understanding, but believing in his teacher, the boy kept training.
Several months later, the master took the boy to his first tournament.
To his surprise,, the boy easily won his first two matches. The third match proved to be more difficult, but after some time, his opponent became impatient and charged; the boy deftly used his one move to win the match. Still amazed by his success, ......

详述Cisco路由器的时间控制策略的应用(2006-05-27 02:03:00)
摘要：在校园网的管理中，客户端的访问控制是重要的一环，我们经常使用Access-list来进行控制，如果和时间相结合，控制起来将更加灵活。Cisco从IOS版本12.0开始引入基于时间的访问表，可以实现某个时间点或时间段的控制，如：我校控制“班班通”教室内的上网时间段为：每个工作日的早上8∶00到下午18∶00允许Web冲浪，其他时间禁止访问Internet。实现基于时间的访问表只需要两个步骤：第一步，定义一个时间范围；第二
步，在访问表中用Time-range引用刚刚定义的时间范围。下面我们就详细介绍一下它的使用方法。
一、定义时间范围
定义时间范围又分为两个步骤。
1.使用Time-range命令来正确地指定时间范围。格式：time-range time-range-nameTime-range-name 用来标志时间范围的，以便在访问表中进行引用。
2.使用Absolute或者一个或多个Periodic语句来定义时间范围，每个时间范围只能有一个Absolute语句，但它可以有多个Periodic语句。（1）格式：absolute [start time date] [end time date]Time以小时和分钟方式（hh:mm）输入时间。Date以日、月、年方式输入日期。如：absolute start 8:00 end 18:00（2）格式：periodic days-of-the-week hh:mm to [days-of-the-week] hh:mmDays-of-the-week产生作用的某天或某几天；参数可以是单一的一天（如 Monday）某几天（Monday到 Friday）或Daily、Weekday或Weekend。
Daily从星期一到星期天。Weekday从星期一到星期五。Weekend星期六和星期日。如：从星期六早上8∶00到星期天晚上18∶00periodic weekend 8:00 to 18:00一周中的每天8∶00到18∶00periodic daily 8:00 to 18:00从星期三的15∶00到星期六的8∶00periodic wednesday 15:00 to saturday 8:00

以太网络建立多个VLAN典型案例(2006-05-27 02:02:00)
摘要：所谓典型局域网就是指由一台具备三层交换功能的核心交换机接几台分支交换机（不一定具备三层交换能力）。我们假设核心交换机名称为：com；分支交换机分别为：par1、par2、par3，分别通过port 1的光线模块与核心交换机相连；并且假设vlan名称分别为counter、market、managing…… 需要做的工作： &n
bsp; A、设置vtp domain（核心、分支交换机上都设置） B、配置中继（核心、分支交换机上都设置） C、创建vlan（在server上设置） D、将交换机端口划入vlan E、配置三层交换 A、设置vtp domain。 vtp domain 称为管理域。 交换vtp更新信息的所有交换机必须配置为相同的管理域。如果所有的交换机都以中继线相连，那么只要在核心交换机上设置一个管理域，网络上所有的交换机都加入该域，这样管理域里所有的交换机就能够了解彼此的vlan列表。 com#vlan database 进入vlan配置模式 com(vlan)#vtp domain com 设置vtp管理域名称 com com(vlan)#vtp server 设置交换机为服务器模式 par1#vlan database 进入vlan配置模式 par1(vlan)#vtp domain com 设置vtp管理域名称com par1(vlan)#vtp client 设置交换机为客户端模式 par2#vlan database 进入vlan配置模式 par2(vlan)#vtp domain com 设置vtp管理域名称com par2(vlan)#vtp client 设置交换机为客户端模式 par3#vlan database 进入vlan配置模式 par3(vlan)#vtp domain com 设置vtp管理域名称com par3(vlan)#vtp client 设置交换机为客户端模式 ......
思科、华为、HARBOUR交换机广播抑制功能的测试报告(2006-05-27 02:01:00)
摘要：一、CISCO2950（version 12.1(9)）的测试
测试过程：
1、搭建如图一所示的网络并进行相应的配置；2、在PC1上用Solarwinds的WAN Killer向外发送30M的广播包；3、在交换机上观察PORT1和PORT2的广播流量也为30M左右，这说明广播被线速交换转发；4、停止发送广播包；5、在PORT1上启用广播抑制命令： storm-control broadcast level 10 storm-control action shutdown 指令说明：命令1控制PORT1的带宽利用率为10M，命令2指广播流量超过10M就触发ACTION将PORT1关闭6、清空端口，用PC1再次向外发送30M的广播包；7、几分钟后，在交换机上观察PORT1已被自动DOWN掉，在交换机上查看PORT1和PORT2的广播流量为10M左右，这说明当广播流量超过设置的门限
值时，交换机就会自动DOWN掉其相应端口。
测试结果分析：
1、CISCO IOS version 12.1(9)或以上版本才支持广播抑制功能；2、CISCO的广播抑制功能是通过对INPUT的广播流量抑制而起作用的，所以实现此功能时需对CISCO的所有用户端口启用广播抑制；3、当广播流量下降到门限值一下时，不能自动打开DOWN掉的端口，需人为开启端口。
二、港湾U2（version: v140B0018）的测试
测试过程：
1、搭建如图二所示的网络并配置相应的IP地址；2、在PC1上用Sinffer向外发送30M的广播流量;3、在PC1、PC2上用Sinffer DASHBOARD监视广播流量为10M，每秒广播包数是16000个，广播被线速转发；4、停止发送广播包；5、启用广播抑制命令： config broadcast-limit on 1000 指令说明：命令设置所有端口每秒钟允许通过的广播包数量是1000个6、清空端口，在PC1上用Sinffer向外发送10M的广播流量；7、在PORT2上用S......
