Port Trunking Provides Higher Availability
The ES-2008 supports IEEE 802.1ad with load distribution control and fail
over recovery. It supports up to 4 groups with each group aggregating
traffic from 1 to 8 ports. The ES-2008 distributes traffic to each trunk
port based on MAC address, and thus balances the traffic load.
VLAN Offers Both Security and Performance
The VLAN feature in the ES-2008 offers the benefits of both security and
performance. VLAN is used to isolate traffic between different users and
thus provides better security. Performance is also enhanced by limiting the
broadcast traffic to the same VLAN broadcast domain.
Port Mirroring Achieves a Better Network Monitoring
Port mirror copies traffic from a specific port to a target port. This
mechanism helps track network errors or abnormal packet transmission without
interrupting the flow of data across the network.
Multicasting and Broadcast Storm Control Optimize Bandwidth Utilization
The IGMP snooping feature reduces multicast traffic and optimizes bandwidth
utilization for bandwidth-consuming applications such as broadcast video.
The per-port broadcast storm control allows a user-defined threshold to
limit broadcast traffic and avoid degrading overall system performance.
Access Control Enhances Network Security
The ES-2008 supports port-based access control for subscriber authentication
and allows system administrators to define a limited number of MAC addresses
that can access the network from a particular port. This feature denies
access of unauthorized devices to communicate through the switch, thus
highly enhancing the network security.
