前言

今天再次復習了下S5700交換機的三層聚合，但是奇怪的是，可能長時間沒接觸，容易忘。。又出問題了，翻了筆記本才發現原來是這個問題。

一、試驗情況

二、命令如下

1.CE1

代碼如下（示例）：

The device is running!<HUAWEI>undo terminal monitor Info: Current terminal monitor is off. <HUAWEI>sys Enter system view, return user view with return command. [~HUAWEI]int [~HUAWEI]interface eth [~HUAWEI]interface Eth-Trunk 1 [*HUAWEI-Eth-Trunk1]undo portswitch [*HUAWEI-Eth-Trunk1]ip add 10.1.1.1 24 [*HUAWEI-Eth-Trunk1]q [*HUAWEI]int g1/0/0 [*HUAWEI-GE1/0/0]undo shutdown [*HUAWEI-GE1/0/0]eth-trunk 1 [*HUAWEI-GE1/0/0]int g1/0/1 [*HUAWEI-GE1/0/1]undo shutdown [*HUAWEI-GE1/0/1]eth-trunk 1 [*HUAWEI-GE1/0/1]q [*HUAWEI]interface LoopBack 0 [*HUAWEI-LoopBack0]ip address 192.168.1.100 32 [*HUAWEI-LoopBack0]q [*HUAWEI]ip route-static 192.168.2.100 32 10.1.1.2

2.CE2

代碼如下（示例）：

The device is running!<HUAWEI>undo terminal monitor Info: Current terminal monitor is off. <HUAWEI>sys Enter system view, return user view with return command. [~HUAWEI]int Eth-Trunk 1 [*HUAWEI-Eth-Trunk1]undo portswitch [*HUAWEI-Eth-Trunk1]ip add 10.1.1.2 24 [*HUAWEI-Eth-Trunk1]q [*HUAWEI]int g1/0/0 [*HUAWEI-GE1/0/0]undo shutdown [*HUAWEI-GE1/0/0]eth-trunk 1 [*HUAWEI-GE1/0/0]int g1/0/1 [*HUAWEI-GE1/0/1]undo shutdown [*HUAWEI-GE1/0/1]eth-trunk 1 [*HUAWEI-GE1/0/1]q [*HUAWEI]int [*HUAWEI]interface LoopBack 0 [*HUAWEI-LoopBack0]ip add 192.168.2.100 32 [*HUAWEI-LoopBack0]q [*HUAWEI]ip route-static 192.168.1.100 32 10.1.1.1

問題出現

問題來了，不通。。。。。

查看問題所在

老樣子，翻出我的老筆記本，發現，原來用S5700交換機做三層聚合的時候，必須得最后退出進行保存配置，否則不生效，所以我又重新來過

1.CE1

代碼如下（示例）：

The device is running!<HUAWEI>undo terminal monitor Info: Current terminal monitor is off. <HUAWEI>sys Enter system view, return user view with return command. [~HUAWEI]int [~HUAWEI]interface eth [~HUAWEI]interface Eth-Trunk 1 [*HUAWEI-Eth-Trunk1]undo portswitch [*HUAWEI-Eth-Trunk1]ip add 10.1.1.1 24 [*HUAWEI-Eth-Trunk1]q [*HUAWEI]int g1/0/0 [*HUAWEI-GE1/0/0]undo shutdown [*HUAWEI-GE1/0/0]eth-trunk 1 [*HUAWEI-GE1/0/0]int g1/0/1 [*HUAWEI-GE1/0/1]undo shutdown [*HUAWEI-GE1/0/1]eth-trunk 1 [*HUAWEI-GE1/0/1]q [*HUAWEI]interface LoopBack 0 [*HUAWEI-LoopBack0]ip address 192.168.1.100 32 [*HUAWEI-LoopBack0]q [*HUAWEI]ip route-static 192.168.2.100 32 10.1.1.2 [*HUAWEI]q Warning: Uncommitted configurations found. Are you sure to commit them before ex iting? [Y(yes)/N(no)/C(cancel)]:y

2.CE2

代碼如下（示例）：

總結

果然啊，老師容易忘記這個很少出現的東西，還是得常復習啊。
