CONTACT-INFO "support@Supermicro.com" DESCRIPTION " The proprietary MIB module is for configuration of DHCP snooping feature. DHCP snooping provides security between the untrusted hosts and DHCP servers, by filtering the Untrusted DHCP packets which is received from out of the network and also updates the IP binding database present in the IPDB module.
