Rate-limiting of DHCP, IGMP,
and ARP control packets at an
ONT UNI port
SOC-based ONTs rate-limit the number of control packets for protocols IGMP, DHCP,
and ARP to 10 control packets per second by ONT UNI port. IGMP is not rate-limited at
an ONT UNI port if an IGMP channel is provisioned for the port.
Gratuitous ARP discard The ability to enable gratuitous ARP discard on an ONT UNI port basis is provided. The
7342 ISAM FTTU supports a discard mechanism that filters incoming traffic for
gratuitous ARP requests. When gratuitous ARP discard is enabled, incoming gratuitous
ARP requests are discarded.
Dynamic source address
anti-spoofing with DHCP
Where the IP or MAC source addresses are not known, dynamic source address
anti-spoofing is available.When dynamic anti-spoofing is enabled, an IP address is
dynamically added to the anti-spoofing table of authorized source addresses when a
host sends a DHCP ACK message, and is deleted when the DHCP lease expires.
Power over Ethernet (PoE)
support for LP MDU and GE LP
MDU
The LP MDU and GE LP MDU support the SWRD (Single Wire Return Device). The SWRD
unit functions as a data conversion device, and an Ethernet connection is used as a
video return channel in the upstream direction. The video return channel is carried
over an HSI service, and returned to the video service provider.
