Hi All ,
I have tw cabinets side by side each other , in one cabinet i have 2 switches and the other just one. These three switches are all C2960X. they work fine now issues . SW1 has a prot channel to SW2 and SW1 also has a port channel to SW3 in the other cabinet.
keep this is mind there is no connection between SW2 and SW3 there shouldnt be any loop , the problem begins if i connect SW4 to SW2 via port channlel.... i start to revceive mac flaps for every vlan , keep in mind there isnt a loop or shouldnt be :
Please help, are there any special considerations i might have missed ?
