 | The ComNet CWGE28MS2 has twenty 100/1000Base-FX SFP ports, four Gigabit combo ports that allow for TX or FX transmission and four 1000Base-FX SFP ports. All SFP ports utilize ComNet SFP* modules for fiber, connector type and distance. The IEEE802.3-compliant unit offers multiple Ethernet redundancy protocols (ERPS G.8032 and MSTP/RSTP/STP) which protect your applications from network interruptions or temporary malfunctions by redirecting transmission within the network. The CWGE28MS implements complete Layer 2 to Layer 4 ACLs to restrict access to your sensitive network resources by filtering specific packets based on TCP/UDP ports, source and destination IP addresses or particular network devices. Furthermore, DHCP snooping, TACACS+, ARP, IEEE 802.1X and Port Security provide additional tools to manage access and levels of use of the network. These defence mechanisms of the CWGE28MS along with advanced DoS auto prevention deliver robust network security and enables network administrators to offer more stable services on a more secure network.
