Comprehensive multicast functions enable various
channel program designs for IPTV providers
Fully IPv6 Compatible
IPv6 compatibility ensures continued reliable usage
by Internet Service Providers (ISPs) when migrating to
next-generation IP networks.
Gigabit Ethernet Connection
Gigabit Ethernet ensures that high-bandwidth
demand can be fulfilled easily.
With the growing demands of IPTV usage, the DGS-1100-05PD is ideal as it provides a variety
of functions to enhance transmission quality and management efficiency, such as IGMP
Snooping, Limited IP Multicast, ISM VLAN, and MLD Snooping for an IPv6 environment. In
Limited IP Multicast, users can set Multicast Address profiles and associate them to a port or
multiple ports, allowing the switch to permit or deny join requests sent by subscribers. The
ability to set a profile eases the management effort required to add or delete subscribers from
a channel package. ISM VLAN (IGMP Snooping Multicast VLAN) needs configuration on both
the access switch and the uplink aggregation L3 switch, and the duplicated stream can be
eliminated in the uplink when users in different VLANs are watching the same channel. While
migrating to IPv6, MLD Snooping takes over and ensures that multicast quality stays high in the
future when IPv6 becomes widely used.
The DGS-1100-05PD also enables security functions to keep the network devices in control.
Through Static MAC, administrators can filter packets sent by non-registered devices. Port
Security can limit the number of MAC addresses learned per port and prevent MAC address
Strong Performance and Redundancy
As a metro access switch, the DGS-1100-05PD is equipped with functions
that help networks remain stable and easy to manage. Supporting Loopback
Detection, it can easily prevent data loops from happening and minimize the
risk of breaking down the network. The DGS-1100-05PD also supports QoS
(Quality of Service). Packets can be classified based on contents, and assigned
to different queues. The prioritization mechanism helps users to differentiate
traffic in terms of service packages and customer levels. The bandwidth control
feature allows network administrators to define the ingress/egress throughput
levels for each port with granularity down to 16 kpbs. The switch also supports
the storm control feature which minimizes problems from excessive traffic
within the network.
The DGS-1100-05PD supports port-based and host-based 802.1X access
control with local server or RADIUS server. Administrators can also put
unauthorized users into Guest VLAN and give them limited access rights.
The switch features a variety of management tools and supports several
communications standards. Configuration can be done through Telnet,
SNMP, and HTTP. The graphical web user interface provides administrators
a straightforward and convenient way to manage their networks. The Link
Layer Discovery Protocol (LLDP) allows the switch to advertise its identity
and capabilities on the local network and to detect neighboring devices, so
that the devices can provide topology information to management software
The DGS-1100-05PD helps administrators do quick troubleshooting and
diagnostics. The Cable Diagnostics function can detect the cable length of
connected cables and display the cable status. This saves administrators a lot
of inconvenience in looking for network problems and conducting repairs.
The DGS-1100-05PD also supports IEEE802.3ah, a data link layer protocol
which provides network administrators the ability to monitor the health of the
network and quickly determine the location of failing links or fault conditions
on point-to-point and emulated point-to-point Ethernet links.
