Compare with the trandition L2/L3network design, VSF provides with multiple markedness advantages. All in
all, we can conclude with 3 main advantages:
1. VSF can increase the efficiency of operation
Only one management point, including configuration documents and gateway IP address (dispense
with HSRP/ VRRP/GLBP). One logical device which is made up by multiple physical devices creates
the simple topology without loop and without the spanning tree protocol (STP). Bottom physical
switches connect together by using standard million-mega Ethernet port; it provides a flexible deploy
option for the location.
2. VSF can optimize the uninterruptedly communication
Switches status conk out switching will not interrupt the applications which are using the internet
