重点说下813,做天刚过的。运气不好,上来两题就是Lacp+MLS,第8、9题的样子又遇到AAA,前10题就把实验题搞定了。后面遇到3道托图和几道有争议的题,没有新题。, c- ~, V$ r* K+ z

我看了两个题库,一个是鸿鹄论坛2013.11.7的题库,一个是论坛里面之前有人发的197的题库。. T$ c7 h5 [) T* l4 J2 O

. B0 M4 @; ?- `8 f先说Lacp,Lacp我按照197的题库,先把fa0/3-4划进channel-group 1,再在port-channel 1 里面做的配置,但是做完后show interface trunk死活看不到信息,不知道是不是bug,没办法,又在interface rangge fa0/3-4接口下面把配置也做了一遍,才ok。所以考试的时候建议大家在两个下面都做。然后需要注意的是interface rangge fa0/3-4这类命令,- 符号的两边都要留一个空格,不然会报错。6 [2 V. h1 Y/ s3 @, d" X3 Y- U4 x

最后有一道托图题,鸿鹄两个题库的答案不一样。我按照197的选的,是正确的。第一次发帖,不知道怎么截图。就是197题库拖图题的第1题,对应是鸿鹄论坛2013.11.7题库的话就是托图第17题。第二个图框要选what routing protocol will be used。大家下载一下附件就好了。4 H g- B; D$ e! g1 y z. L2 \7 a
