Managing a Switch Stack

NSF and DHCP Snooping

Figure 8-14 illustrates an L2 access switch running DHCP snooping. DHCP 

snooping only accepts DHCP server messages on ports configured as 

trusted

 

ports. DHCP snooping listens to DHCP messages to build a bindings 

database that lists the IP address the DHCP server has assigned to each host. 

IP Source Guard (IPSG) uses the bindings database to filter data traffic in 

hardware based on source IP address and source MAC address. Dynamic ARP 

Inspection (DAI) uses the bindings database to verify that ARP messages 

contain a valid sender IP address and sender MAC address. DHCP snooping 

checkpoints its bindings database.

Figure 8-14. NSF and DHCP Snooping

If the Management Unit fails, all hosts connected to that unit lose network 

access until that unit reboots. The hardware on surviving units continues to 

enforce source filters IPSG installed prior to the failover. Valid hosts continue 

to communicate normally. During the failover, the hardware continues to 

drop data packets from unauthorized hosts so that security is not 

compromised.
