If you do show process cpu and show memory cpu when the issue is occurring what does it show? It is possible that your traffic is overloading what the switch is capable of transmitting.
Hi can i see on 172.16.0.50, STP port table, 26 1/xg4 show state is forwarding and role is root, and connect to level 2 (172.16.0.54) switch. i wondering why set the role as Root, any ideas?
The root port is the port with the shortest path to the root switch for STP.
