Switching Loop

MAKhan · ‎05-11-2009

Hello Dear,

How to stop the loop in the switches without enabling spanning-tree on the switches. Let's suppose there are 4 switches in the network and the requirement is NOT TO ENABLE SPANNING-TREE.

thanks in advance.

best regards

Depends on how you connect the switches. If you connect them in a chain ie.

SW1 -> SW2 -> SW3 -> SW4

then you have no issue and can leave STP disabled (altho i wouldn't).

If they are connected to form a square in effect ie.

SW1 -> SW2 -> SW3 -> SW4 -> SW1

then if all vlans are the same on all switches then one of the links would need to be L3 not L2.

Dear Jon,

Thank you for your quick reply, would you be so kind to post a small sample configuration including L3.

Thanks in advance.
