Hi-performance, Network Manageable Fast Ethernet Switch
Proudly presented by OvisLink OV-2252S is the next-generation hi-performance
L2 Ethernet switch with 48 Fast Ethernet ports. It has an advanced
architecture providing 36 Gbps switch fabric, and 13.1 Mpps forwarding rate.
Its hardware wire-speed switching capability provides a powerful, multi-layer
solution not only for enterprises, but also for Internet Service Providers
(ISP’s) and telecom carriers.

OvisLink OV-2252S provides dense Fast Ethernet, enabling enhanced LAN services for
middle-level enterprise, midmarket and ISPs.

The OvisLink OV-2252S also provides:
• Intelligent features at the network edge, such as access control lists (ACLs) and
enhanced security.
• High density port configuration including 48 Fast Ethernet ports
• 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 slot).
• Network control and bandwidth optimization using QoS, granular rate limiting, ACLs,
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
• Lifetime warranty.
• Free software updates.

• Port-based VLAN
• 802.1Q tagged VLAN
• GVRP (GARP VLAN Registration Protocol) to
help management and deploy of VLANs
• Port isolation per VLAN
• QinQ
• Up to 4024 VLAN

- Spanning tree
• 802.1D Spanning tree
• 802.1w Rapid Spanning tree
• 802.1s Multiple Spanning Tree
• Ether-ring protection

- Scalability
• LACP and static Port trunking. Up to 8 groups
with up to 32 ports per group
• Clustering. Manageability through a single P I
address. Up to 256 switches per cluster
• LLDP (Link Layer Discovery Protocol)
• RPS support

- Control
• Traffic control using back pressure at halfduplex
and 802.3x at full-duplex
• Port rate limit. 64K step size
• Storm control. Stop sending at threshold to
prevent unicast/multicast/broadcast storms
• IGMP Snooping for multicast traffic control

- QoS
• HOL (Head Of Line) blocking prevention
• 802.1p tagging (8 priorities)
• 4 dispatching queues per port
• FCFS (First Come First Serve) policy
• Strict priority scheduling algorithm
• WRR (Weighted Round Robin) algorithm
• DSCP (Differentiated Services Code Point)

- Security
• 802.1x port-based authentication
• Remote authentication through RADIUS
• Port Security
• MAC, VLAN and IP ACL for incoming traffic
per port
• Web authentication
• DoS Prevention

- Management
• SNMP v1/2
• RMON groups 1,2,3,9
• CLI (Telnet, console)
• Web interface
• NTP (Network Time Protocol) to provide an
accurate and consistent timestamp to all
intranet switches.
• Port mirroring based on traffic flow
• Software and configuration upload/download
