ETHERNET ACCESS SWITCH MES2348B

• L2+ switches
• Stacking support
• Multicast support (IGMP, IGMP snooping, MVR)
• Extended safety services (L2-L4 ACL, IP Source address guard, Dynamic ARP Inspection and etc.)

The MES Access switch is a controlled switch of L2+ level that have 48 ports 10/100/1000Base-T and 4 ports 10GBase-X (SFP+)/1000Base-X (SFP).

Switches provide end-user connection to the network of big businesses, small and medium-sized businesses and connection to the network of communication providers via Gigabit Ethernet interfaces.
Switch functionalities provide physical stacking, support of VLAN and multicast groups and extended safety services.
