RC1201-2GE16E1T1 Product Description
Link aggregation helps share traffic among members in an aggregation group. In addition to
effectively improve the reliability on links between devices, link aggregation can help gain
higher bandwidth without upgrading hardware.
The RC1201-2GE16E1T1 support manual link aggregation. The process of aggregating
multiple physical ports to a logical interface does not require any protocol. The consistency of
interface parameters is ensured manually. The RC1201-2GE16E1T1 supports 16 link
aggregation groups and each group support 8 interfaces.
3.7 Storm control
On most Layer 2 network, unicast traffic is much heavier than broadcast traffic. If rate for
broadcast traffic is not limited, when a broadcast storm is generated, total bandwidth will be
occupied. Therefore, network performance is reduced and unicast packet cannot be forwarded.
In addition, communication between devices may be interrupted.
Configuring storm control on RC1201-2GE16E1T1 prevents broadcast storm occurring when
broadcast packets increase sharply in the network. Thus, ensure that the unicast packets can
be properly forwarded.
Broadcast traffic may exist in following forms, so you need to limit the bandwidth for them
on RC1201-2GE16E1T1.
3.8 Routing
Routing is a behavior to transmit packets to the destination through the network. During the
transmission process, packets are forwarded according to routing table. The RC1201-
2GE16E1T1 supports default gateway and static routes without dynamical routes.
There are two ways to route packets:
Unknown unicast traffic: the unicast traffic whose MAC destination address is not in
MAC address table. It is broadcasted by the RC1201-2GE16E1T1.
Unknown multicast traffic: the multicast traffic whose MAC destination address is not in
MAC address table. Generally, it is broadcasted by the RC1201-2GE16E1T1.
Broadcast traffic: the traffic whose MAC destination address is a broadcast MAC
address. It is broadcasted by the RC1201-2GE16E1T1.
Using a default gateway: the default gateway sends data flow of which the next hop is
unknown to the default router.
Using static routes: with manual configuration of routes, the RC1201-2GE16E1T1
forwards packets from specified ports. This is applied for simple networks.
