LACP 那一条switch B 是LAYER3,对於有同志说经常执行SH RUN 後, int port-channel 1 都看不见sw mo trunk,
9 p) e2 a& ~. s* g+ d小弟的做法是 int range fa0/3 - 4) c7 V/ ` f- V
sw tr encap dot1q
. v4 b9 b# O$ Gsw mo trunk7 N5 e0 P1 d0 r1 Y+ N: A7 a

他就能够出现sw mo trunk3 R A! ]; ]4 L) Q R. Y

AAA 那一条题目的最底部份写了由於日後会用到RADIUS AUTHEN 类似之眼,所以 SHOW DOT1x statics 都不会有什麽能看到, f6 e# W# k9 e7 {4 N: w8 y& s

总结:拖拉题不要单纯背单边,最好两边都背下。题库都精准的
