An S3100-C-EPON-EI series Ethernet switch with an ONU sub-card can operate as an EPON
ONU. To disable an EPON ONU from dropping unknown unicast packets, use the
unknown-multicast drop enable [ pon-ignore ] command.

Use the unknown-multicast drop enable command to enable the switch to drop unknown multicast
packets.
Use the unknown-multicast drop enable [ pon-ignore ] or undo unknown-multicast drop enable
command to disable the switch from dropping unknown multicast packets.
By default, a common Ethernet switch does not drop unknown multicast packets.
On an Ethernet switch operating as an EPON ONU:
Use the unknown-multicast drop enable command to enable the EPON ONU to drop unknown
multicast packets.
Use the unknown-multicast drop enable [ pon-ignore ] command to disable the EPON ONU from
dropping unknown multicast packets.
