something new to me, wish netpro can share to me and guide me how to resolve this.
Upstream Switch A- model WS-C3750G-12S-S (version 12.2(35)SE5)
Downstream Switch B - Model WS-C3560-24PS-S ( version 12.2(35)SE5)
vtp domain - jack
vtp mode - transparent.
vtp version - 2
when i configured both switch as trunk and dot1Q. it doesn't work.
so, i tried to change it to access vlan. and it work successful.
i am curious. what wrong with this ?
