I have a Nexus 5548UP trunked to a Catalyst 2960S. I have verified that spanning tree is working. I explicitly made the 2960S the root bridge for all VLANs as a temporary measure since it is trunked ...
How can I prevent the Cisco Catalysts 2950/2960/3550/3750 from being vulnerable to ARP Poisoning? Can this be avoided with the ARP INSPECTION? Thanks
