4.12.8 DHCP Snooping 

DHCP Snooping is used to block intruder on the untrusted ports of DUT when it tries to intervene by injecting a bogus DHCP 

reply packet to a legitimate conversation between the DHCP client and server.   

 

 

 

Configure DHCP Snooping on this page. The DHCP Snooping Configuration screen in
