The E4800G Gigabit family delivers outstanding security, reliability, and multi-service support capabilities for robust switching at the edge or aggregation layer of large enterprise and campus networks, or in the core layer of medium- and small-sized enterprise networks. the family is comprised of Layer 2/3/4 Gigabit Ethernet switches that can accommodate the most demanding applications, providing resilient and secure connectivity and the latest traffic-prioritization technologies to optimize applications on converged networks. Designed for maximum flexibility, these switches are available with 24 or 48 Gigabit ports. Power over Ethernet (PoE) and non-PoE models are offered with optional 10-Gigabit expansion capability and SFP mini-GBiC Gigabit combo ports for fiber flexibility. The all-SFP model with dual power supplies, for highest availability applications, allows for very flexible fiber with copper Gigabit connectivity.

Management

• IEEE 802.1AB Link Layer Discovery Protocol (LLDP): automated device discovery protocol provides easy mapping by network management applications


Connectivity

• Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100 and 10/100/1000 ports


Resiliency and high availability

• Spanning Tree Protocol (IEEE 802.1D): provides redundant links while preventing network loops


Manageability

• Advanced IRF technology stacking: - locally connect up to nine E4800G switches using 10-Gigabit or CX4 local connections. - improve resiliency by spreading aggregated links across multiple stacked units. - see faster performance through a distributed routing architecture where locally bound traffic is handled at each unit. - simplified management with single IP management and a unified control interface per stack.


Layer 2 switching

• VLAN support and tagging: support the IEEE 802.1Q. 4094 VLAN IDs with all working simultaneously


Layer 3 services

• ARP: determines the MAC address of another IP host in the same subnet; supports static ARPs; gratuitous ARP allows detection of duplicate IP addresses; proxy ARP allows normal ARP operation between subnets or when subnets are separated by a Layer 2 network


Layer 3 routing

• Layer 3 IP routing: provides routing of IP at media speed; supports static routes, RIP, RIPv2, and OSPF
