Hello, We have a BD8810 core switch and few models of Extreme EXOS Edge switches (like X430, X440, X460). All of our servers are connected to our core switch. Clients are connected in our Edge Switches. Our core switch having multiple VLAN's. Each vlan have own Tag ID. So, required VLAN's are created in our Edge Switches with relevant Tag ID in core switch. Now, the issue is, From past two days we are facing a issue while pinging the Gateway IP addresses of each VLAN's which are configured in our core. The issue is, reply time in ms is more than 150ms. It was less than 1ms previously. We don't know where the actual issue is? In configuration or is any loop or any slot problem in core. Please help us to resolve this issue.
