Q:
How can I protect Nebula switches against rogue DHCP servers?
A:
To protect your Nebula switches from rogue DHCP servers, you can enable the IP Source Guard feature in Nebula.
IP Source Guard consists of two integrated security mechanisms:
- DHCP Snooping – Allows the switch to build a trusted IP-to-MAC binding table by monitoring DHCP traffic.
- ARP Inspection – Uses the DHCP Snooping binding table to validate ARP packets and prevent spoofing attacks.
These two features are integrated and function together to enhance network security.
