IGMP Snooping enable: IGMP Snooping is the process of listening to IGMP
traffic. IGMP snooping, as implied by the name, is a feature that allows the EOC
Modem to "listen in" on the IGMP conversation between hosts and routers by
processing the layer3 IGMP packets sent in a multicast network
DHCP Snooping enable: DHCP snooping performs two main tasks:
Keeping a record of which IP address are currently allocated to hosts
downstream of the ports on the EOC Modem.
Deciding which packets are candidates for having Option 82 information
inserted, and actively filtering out packets that are deemed to be invalid
DHCP packets.
NetBIOS blocking enable: Blocking SMB protocol, exp. TCP/UDP 137-139,
UDP 445
Maximum DHCP session manager: Counting final DHCP ACK, and check to
half Least Time alive?
DHCP Option 82 enable: DHCP Relay Agent Information Option 82 is an
extension to the Dynamic Host Configuration Protocol (DHCP), and is defined in
RFC 3046.
