The T4340a switch supports Layer 2 bridging and Layer 3 IPv4/v6 unicast and multicast routing with Layer 2 through Layer 4 advanced traffic classification, filtering and prioritization. It is designed for applications requiring strict data prioritization and filtering, advanced traffic classification and traffic monitoring, as well as delay-sensitive and critical environments. Four of the 24 GigE ports and two of the 10 GigE ports come out the front of the switch; 16 ports are accessible via the rear and are configurable in groups of four as 1000BT or 1000Kx ports. Additional functions on the fully-managed version include monitoring of all statistical counters and an extensive list of remote monitoring counters.
