Manageable L3

Hi-performance, Network Manageable Fast Ethernet Switch
OvisLink is proud to present the OV-3252S the next-generation hi-performance
L3 Ethernet switch. It has an advanced architecture, 36 Gbps switch
fabric, and 13.1Mpps L3 forwarding rate. Its hardware wire-speed L3 switching
capability provides a powerful, multi-layered solution not only for enterprises,
but also for Internet Service Providers (ISPs) and telecom carriers.

OvisLink OV-3252S is an enterprise-class switch providing Fast Ethernet and Gigabit
Ethernet configurations. The OvisLink OV-3252S is an ideal distribution layer switch
for enterprise LAN or branch-office environments, enabling the deployment of new
applications such as IP telephony, video surveillance, building management systems, etc.
Customers can deploy network intelligent services such as quality of service (QoS), rate
limiting, access control lists (ACL s), NAC , multicast, and high-performance IP routing
while keeping the simplicity of traditional LAN switching.

The OvisLink OV-3252S provides:
• Intelligent features at the network edge, such as sophisticated access control lists
(ACL s) and enhanced security.
• Combo Gigabit Ethernet ports flexibility, allowing use of either a copper or a fiber
uplink. The combo port has one 10/100/1000 Ethernet port and one Small Form-Factor
Pluggable (SFP)-based Gigabit Ethernet port, with one port active at a time (using
expansion modules)
• Network control and bandwidth optimization using QoS, granular rate limiting, ACLs
(L2-L4), and IGMP Snooping.
• Network security through a wide range of authentication methods, and Network Access
Control based on users, ports, and MAC addresses.
• Extended manageability using CLI.
• Manageable through cluster technology allowing management using only one IP
• Dynamic unicast IP routing, including the most popular and standard protocols such as
RIPv1/2, OSPF, BGP and a Cisco EIGRP compatible (BEIGRP)
• In addition to dynamic IP unicast routing, the OV-3252S is perfectly equipped for
networks requiring multicast support providing Protocol Independent Multicast (PIM)
and Internet Group Management Protocol (IGMP)
• IP services such as DHCP, Proxy ARP and NAT
• Reliability using Virtual Router Redundancy Protocol (VRRP)
• Automatic recognition for straight-through or cross-over cables.
• Lifetime warranty.

and 802.3x at full-duplex
• Port rate limit. 64K step size
• Storm control. Stop sending at threshold to
prevent unicast/multicast/broadcast storms
