ComNet Communication Networks, a specialist in fibre optic and Ethernet network solutions, has introduced a high capacity managed Ethernet switch. The Comworx CNGE2FE24MSPoE is described as the company's first environmentally hardened Managed Ethernet Switch, providing a high port density in a compact package plus power over Ethernet to peripheral devices such as IP cameras and video encoders.
The unit makes available 24 10/100TX ports and two 1000Mbps combo ports that use easily interchangeable small form factor pluggable optic (SFP) devices as optical interfaces. This hardened Ethernet switch is designed to operate in environments where extremes of temperature and vibration are a consideration. All 24 ports support IEEE.802.3af based PoE. Two ports are Gigabit configurable for copper or fibre media for use with multimode or single mode optical fibre, selected by optional SFP modules.
"The new unit offers three significant features," states Vic Milani, ComNet's Vice President of Product Management. "The first is IGMP (Internet Group Management Protocol) snooping V1/V2 for multicast filtering and IGMP Query V1/V2. Without IGMP, multicast traffic (streaming video) is transmitted to all ports within the entire network. This unnecessary traffic floods and ultimately slows the performance of the network. IGMP allows the data to be directed to a specific network address.
"The second feature is Rapid Spanning Tree Protocol (IEEE 802.1w), which provides a redundant network path in the case of a failure on the network. In most cases networks that use ComNet managed Ethernet switches can, in the event of a failure, redirect the data paths allowing network restoration in less than a second.
"Lastly, port based Virtual Local Area Network (VLAN) (IEEE 802.1Q). VLANs address issues such as scalability, security, and network management."
