Switching

Course Description

Dynamic ARP Inspection (DAI) is a security feature that protects ARP (Address Resolution Protocol) which is vulnerable to an attack like ARP poisoning. DAI checks all ARP packets on untrusted interfaces, it will compare the information in the ARP packet with the DHCP snooping database and/or an ARP

These lessons cover everything that has to do with switching. We start with the basics of how switches learn MAC addresses, what VLANs and trunks are and how spanning-tree is used to create loop-free topologies. You will also learn more complex topologies like SDM, CEF and stackwise.
