authentication can be managed by number of client per port and dynamic secure
authentication based on MAC addresses..
„
Spanning Tree
ES4700BD provides support for IEEE 802.1D Spanning Tree Protocol (STP), IEEE
802.1w Rapid Spanning Tree Protocol (RSTP), and IEEE802.1s Multiple Spanning Tree
Protocol (MSTP). Spanning-Tree Protocol is a link management protocol that provides
path redundancy while preventing undesirable loops in the network.
„
Bandwidth Management (Port bandwidth Limit)
ES4700BD features upstream and downstream bandwidth management for both,
enabling different access bandwidth to be specified according to user levels. Each port
can be assigned with different bandwidth to meet the management demands of Access
networks.
„
Trunk Port
Trunk port of IEEE802.3ad is supported by ES4700BD. A Trunk group of 2 to 8 ports
can be established for link redundancy and load balance.
„
IGMP Snooping
ES4700BD supports IGMP Snooping based on multi-casting applications enabling
various multi-cast services (e.g. multimedia playback, remote education and recreation) in
an access network with lowered network traffic.
„
Broadcast Storm Control
ES4700BD can effectively prevent broadcast storms from wasting bandwidth with
packet level Broadcast Storm Control function, resulting in improved overall system
performance.
„
Port Mirroring
ES4700BD supports Port Mirroring, which is used to mirror the inbound and/or
outbound traffic on specific port(s) to another port to gather related statistics, which is
useful in troubleshooting and traffic monitoring.
„
DHCP Server, Relay and Client
ES4700BD supports a DHCP Server. It can dynamically assign IP addresses to hosts
or MAC addresses, and specified IP addresses to implement MAC-IP binding.
„
RADIUS
ES4700BD supports RADIUS (Remote Dial-In User Service) authentication, enabling
users to be authenticated via IEEE802.1x protocols.
„
Comprehensive Network Management
With ES4700BD, in-band and out-of-band management can be done through
Console, Telnet and SNMP. Console and Telnet management provides simple and easy
CLI (command line interface). SNMP management is V1 and V2C compliant, supporting
Ether-Like MIB, Bridge MIB and MIB II, and RMON 1/2/3/9 MIB. With Edge-Core's
ECview, full SNMP network management is available. Furthermore, ES4700BD provides
a unique workstation IP setting management, enabling the switch to filter unauthorized
remote network administrative connections, and keep the validity, security and
consistency of remote network management.
