I'm trying to setup port channel between Cat2900xl and Cat5500 so there would be 200mb connection between them.
I issued "set port channel 4/23-24 mode on" on Cat5500 and issued "port group 2" on interface 23&24 on Cat2900xl.
Well, it didn't work. :( All of the server on Cat2900xt switch dropped.
Does anyone know what did I do wrong?? And can anyone direct me to solve this problem??
