配置流程圖配置接口IP地址配置接口的屬性配置以太網(wǎng)端口匯聚 2 配置步驟（1）配置接口IP地址。（2）配置匯聚的端口屬性在配置端口匯聚之前，首先要保證Sw1和Sw2所有匯聚的端口必須工作在全雙工方式下，而且必須工作在相同的速率下（不能工作于自協(xié)商模式）。（3）配置端口匯聚3結(jié)果驗證在配置完IP地址后，用Ping檢查兩臺交換機(jī)之間的互通性顯然這個組網(wǎng)圖會導(dǎo)致交換機(jī)之間的環(huán)路的存在，主要表現(xiàn)就是出現(xiàn)廣播風(fēng)暴，交換機(jī)數(shù)據(jù)轉(zhuǎn)發(fā)燈不停的閃爍。廣播風(fēng)暴可能會導(dǎo)致連接在交換機(jī)網(wǎng)口上的Pc反應(yīng)速度變慢，如果出現(xiàn)這種情況，可以先拔掉一根網(wǎng)線消除環(huán)路，待配置好端口匯聚以后再將其插上，此時廣播風(fēng)暴就不會發(fā)生了。（1）檢查配置的正確性Sw1display linkaggregation Master port: Ethernet0/1 Other subports: Ethernet0/2 Mode: both（2）驗證端口匯聚的互為備份這個特性。首先在Sw1上用Display Mac命令檢查MAC地址表，查看目前Sw2的Interface Vlan 1的MAC地址在E0/1還是E0/2，Sw2的Interface Vlan 1的MAC地址可以通過在Sw2上利用命令Display Interface Vlan 1觀察到。Sw1display macMAC ADDR VLAN ID STATE PORT INDEX AGING TIME00e0fc262f3c 1 Learned Ethernet0/2 AGING 1 mac address(es) found Sw2display interface

掌握TFTP配置【實(shí)驗學(xué)時】 建議2學(xué)時【實(shí)驗原理】一、 TFTP配置1 TFTP簡介TFTP（Trivial File Transfer Protocol）是一種簡單文件傳輸協(xié)議。相對于另一種文件傳輸協(xié)議FTP，TFTP不具有復(fù)雜的交互存取接口和認(rèn)證控制，適用于客戶端和服務(wù)器之間不需要復(fù)雜交互的環(huán)境。TFTP協(xié)議一般在UDP的基礎(chǔ)上實(shí)現(xiàn)。TFTP協(xié)議傳輸是由客戶端發(fā)起的。當(dāng)需要下載文件時，由客戶端向TFTP服務(wù)器發(fā)送讀請求包，然后從服務(wù)器接收數(shù)據(jù)，并向服務(wù)器發(fā)送確認(rèn)；當(dāng)需要上傳文件時，由客戶端向TFTP服務(wù)器發(fā)送寫請求包，然后向服務(wù)器發(fā)送數(shù)據(jù)，并接收服務(wù)器的確認(rèn)。TFTP傳輸文件有兩種模式：一種是二進(jìn)制模式，用于傳輸程序文件；另一種是ASCII
