Support for 10G Ethernet
10Gb Ethernet (10GbE) is a leap of Ethernet in both speed and distance, in which
full-duplex technology is employed, thus avoiding low-speed, half-duplex CSMA/CD
protocol. Moreover, 10GbE maintains the essence of the original Ethernet model,
therefore can integrate with the current Ethernet environment seamlessly. ES4700BD
supports multi-port 10Gb fiber modules, providing wider bandwidth and more powerful
processing capacity, therefore simplifying network structure and lowering network
infrastructure cost. It is an ideal solution for MAN/WAN applications.
„
MAC Address Control
In addition to the standard MAC address dynamic learning, ES4700BD introduces
several MAC table-based management functions. MAC address binding achieves secure
access through the curb of connecting MAC address on the ports. The MAC filtering
function can screen unauthorized access devices through MAC address filtering.
„
VLAN Configuration
ES4700BD support standard IEEE802.1Q VLAN, port-based VLAN and GVRP
VLAN. IEEE802.1Q VLAN can divide ports into up to 4094 VLAN groups. When
IEEE802.1Q VLAN tagging is used, cross-switch VLAN grouping can be enabled to
manage broadcasting traffic, offer better security and improved network performance.
GARP VLAN Registration Protocol (GVRP) based VLANs can achieve dynamic VLAN
registration via GARP (Generic Attribute Registration Protocol), therefore a more flexible
VLAN application results by reducing VLAN configurations due to less VLAN configuration
changes.
„
Layer 3 Forwarding
Layer 3 forwarding is the forwarding of Layer 3 packets (IP packet) across VLANs,
which ES4700BD uses switch chip hardware to forward IP packets, facilitating the on-chip
host route entries and default routing table entries, allowing IP packets to be forwarded at
full wire speed.
„
Layer 3 Routing Protocols
ES4700BD supports static routing (RIP, OSPF and BGP routing protocols) and
Multicast Protocols (IGMP, IGMP Snooping, PIM-SM, PIM-DM and DVMRP), Policy
Routing, IPv6, and Load Balance etc.
„
QoS
ES4700BD supports various QoS policies. It provides 8 priority queues for each port
with bandwidth that can be individually set. WRR/SP/SWRR scheduling are also
supported. Traffic can be sorted by ports, VLAN, DSCP, IP precedence and ACL, etc. By
assigning different DSCP, IP priorities and bandwidth, different service quality for voice,
data and video transmissions can be achieved.
„
ACL
ES4700BD supports standard and extended ACLs. ACL is an IP packets filtering
mechanism employed by switches, providing network traffic control by granting or denying
access through the switches, and thus effectively safeguarding the security of networks.
ES4700BD can filter inbound IP-based traffic by source/destination IP/Mac addresses, IP
protocol types, TCP/IP port numbers, IP Precedence and ToS information.

IEEE802.1x Access Authentication
ES4700BD supports port-based IEEE802.1x access authentication. Access
