427 49356123 7068699 6982 49.56% 37.34% 36.96% 0 SISF Main Thread
I have some research and everyone is agree that this is because the implementation of dhcp snooping, but i need DHCP snooping operation,
Can anyone help me with other solutions besides disabled DHCP snooping o how can i find the VLAN that is causing this issue, according to some forum disabled DHCP snnoping to just one VLAN is enough.
