❖
Advanced RSTP implementation
The SWT not only complies with the STP and RSTP protocols for resolving loops in the
network and operation in rings, but it also exceeds the recovery times obtained through
said protocols. Thus, the SWT guarantees recovery times lower than 4 ms per link via the
RSTP standard in case of failure.
❖
Critical services and security.
The different services have their level of importance. For example, sending orders to
open a switch has priority over the traffic from a telephone connection. The SWT has
Quality of Service (QoS), which identifies critical services, guaranteeing that all traffic
receives the appropriate priority.
On the other hand, the SWT implements different security features that prevent
unauthorized access to the traffic system, such as: port disabling, traffic restriction
according to MAC addresses, authentication protocols (, RADIUS), etc.
❖
Broadcast traffic limitation.
In order to avoid the network flooding, the SWT establishes maximum volume limits for
different combinations of broadcast, multicast, and flooding messages, in each one of
their ports.
