Don't count on it, it's irresponsible.:) The only things that really differentiate one line card from another are the physical layer interface module (PLIM) and the Layer 3 Forwarding Engine. Each LC can be divided into three major sections: Physical Layer Interface Module (PLIM) - This is the hardware module that terminates the physical connection (media dependent; therefore, Asynchronous T...
The statements inside your source files are generally executed from top to bottom, in the order that they appear. Control flow statements, however, break up the flow of execution by employing decision making, looping, and branching, enabling your program to conditionally execute particular blocks of code. This section describes the decision-making statements (if-then, if-then-else, switch...

在不久的将来，IT经理们将可以更容易地提取和查看路由器中存储的重要通信流量统计数据，这样他们便能更好地管理其网络。 IETF正制订一种格式的标准，利用该格式可从路由器将有关网络通信流量的信息导出至数据 采集设备和网络管理系统。这种拟议中的标准被称为IP流量信息导出（IP flow Information Export，IPFIX），它可以兼容各厂商支持IP协议的路由器和应用。 换句话来说，IT部门以后再也不需要为只支持自有导出格式的路由器专...
Using Java operators An operator takes one or more arguments and produces a new value. Addition(+), subtraction and unary minus(-), multiplication(*), division(/), and assignment(=) all work much the same in any programming language. All operators produces a value from their operands. In addition, an operator can change the vlaue of an operand. This is called a side effect. Almos...

在沒有高級的 cisco 時,該如何做 netflow 流量統計呢? fprobe 會是你的好選擇... 安裝路徑在 /usr/ports/net-mgmt/fprobe/ 不需要用什麼特殊參數... 裝完之後，假設你接 switch mirror port 的網卡是 bge0 則 /usr/local/sbin/fprobe -i bge0 127.0.0.1:9991 可以丟給本機 127.0.0.1 也可以丟到遠端的主機去.. 這樣就會產生 netflow 的資料了.. 再利用 flow-capture 來接收資料 /usr/local/bin/flow-capture -z 6 -n 143 -e 8928 ...
