感谢乔班主和Bit886兄发送的新题库,不过最好看一遍原题,他们两个题答案写的不完全。题库变了,考试花费两个小时。

7 Y9 B- U! K6 S4 B 实验题三道:AAA、LACP、HSRP CASE2。LACP费时60分钟,主要是敲完switchport trunk allowed vlan 1,21-23; siwtchport trunk native vlan 99.EtherChannel就变为SD了,重新配、换到port-channel 2也不行,怀疑是系统BUG,干脆不理。你们最好是敲完上面两条命令,再no shutdown会好些。! B6 z: ]' G J
SwitchA没有switchport trunk encapslution dot1q命令,不用管它。
