Flow control
|
Backpressure is adopted for half-duplex, while IEEE802.3x is adopted for full-duplex.
CAR, a 64K step limitation is conducted to the 100M port, and a 8M step limitation is conducted to the gigabit port.
|
Storm control
|
The broadcast storm is constrained. When the threshold value for controlling the broadcast storm is reached, the broadcast packets are stopped from being forwarded.
|
Multicast
|
IGMP Snooping v1/v2/v3
|
Aggregation
|
Each port binding group contains up to 8 ports, and 6 port binding groups are supported meanwhile.
Dynamic LACP or static aggregation is supported.
|
Mirroring
|
Flow-based or port-based mirroring
|
Stacking
|
