I have a dummy question again.
| | ------ ISL_1------ | |
| | ------ ISL_2------ | |
| | | |
| Switch_A | | Switch_B |
| | | |
| | ------ ISL_3------ | |
| | ------ ISL_4------ | |
I have two Trunks:
Let's say Host_X is sending frames from Switch_A to Switch_B through ISL_1; at the same time, ISL_1 is broken.
Thank you for your guidance in advance.

if ISL_1 goes down and there was a frame on it, frame will be lost.
When farme is lost, the whole exchange which the lost frame was part of, have to be resend.
All exchanges traversing trunk isl_1/isl_2 having no frame lost will be uninterrupted on isl_2 only.
Depending on your routing policy on the switches, the next exchanges will be routed either via trunk isl_3/4 or isl_2.
