I have a core and several access switches. I have RVI configured for my VLAN at the core. I have 1 RVI configured for each access switch for the gateway. When I configured arp-inspection and dhcp-examine for all of my VLANs. The whole network went down. The access switches do not like those port security commands for all VLANs.
I am trying to understand why my network went down when I configured those port security commands. Thx
