REASON SWITCHES-TM-EN-3

5 Key Features

 Packet transmissions done by hardware, with a maximum switching capacity

(throughput) of 48 Gbps;

 Automatic learning, auto-negotiation and automatic detection/treatment of

polarity at the copper ports (RJ45 connectors);

 Store-and-forward packet switching;

 Support to IPv4 and IPv6 protocols (Multicast, Unicast and Broadcast);

 Storm detection and control (Multicast, Unicast and Broadcast storm types);

 SSH text mode configuration on a safe connection;

 SSL graphic mode configuration on a safe connection;

 Native and remote authentication and authorization through RADIUS and

TACACS+;

 Remote monitoring through RMON;

 SNMP v1/v2c/v3 traffic mirroring and monitoring functions;

 IP multicast management through IGMP v2/v3 (for IPv4 applications) and MLD

v1/v2 (for IPv6 applications);

 VLAN traffic segregation (IEEE 802.1Q), and up to 4095 VLANs allowed;

 Traffic prioritization (up to 8 Class of Service levels) using QoS (IEEE 802.1Q);

 Loop detection and protection through Spanning-tree protocols: STP, RSTP (IEEE

802.1D) and MSTP (IEEE 802.1Q);

 Loop detection and protection function without Spanning-tree protocols;

 Automatic loop detection with Log and/or Shutdown port;

 Automatic topology detection (ring or mixed-topologies which use redundant

path) and reconfiguration in case of loop detected;
