Multicast
DGS-1100-10 / ME provides an opportunity to work with IPTV-service, or any other, based on the transmission of multicast traffic, enjoys a growing demand in the market, thanks to the support functions such as IGMP Snooping, Limited IP Multicast (Restriction of multicast on IP-addresses) , ISM VLAN and MLD Snooping. Using these functions, enables optimum bandwidth while preserving a high quality of data transmission. Limited IP Multicast function allows you to create profiles multicast and link them to ports or port ranges to allow or deny requests to connect to a particular group (channel) that are sent to users. Using profiles simplifies the management of IPTV service in case the user changes the package. When using the ISM VLAN (IGMP Snooping Multicast VLAN) multicast traffic for the purpose of efficient spending bandwidth transmitted in a separate VLAN. When using the ISM VLAN (IGMP Snooping Multicast VLAN) configuration is necessary on the access switch, and the L3 switch level of aggregation. Bandwidth savings achieved in the case of viewing the same channel in different customer VLAN, it does not require a separate copy of the multicast traffic for each of them in the case of using the ISM VLAN. MLD Snooping function improves the efficiency of multicast and can reduce costs during the transition to IPv6.

Security
DGS-1100-10 / ME also supports security features. Through the use of Static MAC mechanism can allow access only to authorized devices. Port Security allows you to limit the number of MAC-addresses, studied at the port, and prevent flood-attacks against overflow switching table.

High performance and fault tolerance
Switch DGS-1100-10 / ME supports a wide range of functions to ensure smooth operation and simplifies management. Support Loopback Detection prevents the formation of loops in the network. DGS-1100-10 / ME also supports QoS (Quality of Service).Packets may be classified based on the contents and distribute a different priority queue processing. Prioritization mechanism helps to differentiate traffic based on quality of service requirements. With Bandwidth Control allows network administrators to define bandwidth for each port in increments of 16 kbit / s for incoming and outgoing traffic. The switches also support the functional protection from the storm (Storm Control), which allows you to get rid of unnecessary traffic.

Authentication
DGS-1100-10 / ME supports 802.1x authentication on the port-based / node, and authentication based on the local database or RADIUS-server. Administrators can also put unauthorized users in Guest VLAN and assign them limited access rights.
