It is also an excellent choice as a small enterprise core switch for Gigabit to the Desktop migration. Ethernet Switch Key Features and Benefits Performance and Scalability The ES4625/ES4549 provides 1 optional 10 Gigabit Ethernet module for 10G uplink to fulfill any bandwidth-eager customer. Optional 10 Gigabit Ethernet XENPAK transceivers can be chosen for different distance fiber uplinks. Start stacking up to 8/4 units for a total of 192 10/100/1000 ports and 8 10G ports for pay as your network expands style. A switch stack can be managed with a single IP address and as a single entity for greater management simplicity. 40 Gbps stacking bandwidth for intra-switch data transfer. Backup Master ensures the availability of a master controller for network control at any time. Redundant Stacking ensures continued operation of other units while adding or removing a unit, or in the unlikely event of unit or stacking cable failure. Firmware and configuration are automatically upgraded from master to slave units for management simplicity. Continuous Availability IEEE 802.1w Rapid Spanning Tree Protocol provides a loop-free network and redundant links to the core network with rapid convergence. IEEE 802.1s Multiple Spanning Tree Protocol runs STP per VLAN base, providing Layer 2 load sharing on redundant links. IEEE 802.3ad Link Aggregation Control Protocol (LACP) increases bandwidth by automatically aggregating several physical links together as a logical trunk and providing load balancing and fault tolerance for uplink connections. IGMP snooping prevents flooding of IP multicast traffic, and limits bandwidth intensive video traffic to only the subscribers. Optional Redundant Power Supply provides uninterrupted power. L3 Features The ES4629/ES4649 delivers high- performance, hardware based IP routing. RIP and OSPF provides dynamic routing by exchanging routing information with other Layer 3 switches or routers. DVMRP, PIM-DM Multicast Routing Protocols send IP multicast traffic from one subnet to another. VRRP prevents your system from failing by dynamically backing up multiple L3 switches for routing. Comprehensive QoS 8 egress queues per port enable differentiated management of up to 8 traffic types. Traffic is prioritized according to 802.1p, DSCP, IP precedence and TCP/UDP port number, giving optimal performance to real- time applications such as voice and video. Bidirectional rate-limiting, per port or traffic class, preserves network bandwidth and allows full control of network resources. Enhanced Security IEEE 802.1X port-based access control ensures all users are authorized before being granted access to the network. Access Control Lists (ACLs) can be used to restrict access to sensitive network resources by denying packets based on L2/L3/L4 headers. SSL, Web Management Encryption, RADIUS and TACACS+ protect data communication and ensure data privacy. Simple Management Industry standard Command Line Interface (CLI) via console port or Telnet can be usedfor switch management. Embedded user friendly web interface helps users quickly and simply configure switches. Support four groups of RMON. Backup and restore Firmware and configuration files via TFTP.
