INSTALLATION AND OPERATION MANUAL
CWGE24MS2
COMMERCIAL GRADE MANAGED LAYER 2+ ETHERNET SWITCH
WITH 20 × 100/1000BASE-FX + 4 × GIGABIT COMBO PORTS
v1.0 November 29, 2016
The ComNet CWGE24MS2 has twenty 100/1000Base-FX SFP ports and four Gigabit
combo ports that allow for TX or FX transmission. 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 CWGE24MS2 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 CWGE24MS2 along with advanced DoS
auto prevention deliver robust network security and enables network administrators
to offer more stable services on a more secure network.

    INSTALLATION AND OPERATION MANUAL CWGE24MS2 STP/RSTP Introduction (R)STP detects and breaks network loops and provides backup links between switches, bridges or routers. It allows a Switch to interact with other (R)STP compliant switches in your network to ensure that only one path exists between any two stations on the network.

Forward Time (Forward Delay): This is the maximum time (in seconds) the Switch will wait before changing states. This delay is required because every switch must receive information about topology changes before it starts to forward frames.
