CS3-248FC4TF Series Layer 3 Managed Switch

NetLink CS3-248FC4TF series switches are L3 10G Switches based on the new generation of high-performance hardware and NetLink Operating System Platform (TOS). It provides a large capacity, high-density GE interfaces, and 10GE uplink interfaces. With extensive service features and IPv6 forwarding capabilities, and supports Static Routing, RIP, and OSPF, the CS3-248FC4TF series switches is applicable to various scenarios. For example, it can be used as an access or aggregation switch on campus networks or an access switch in data centers. CS3-248FC4TF series switches integrate many advanced technologies in terms of reliability, security, and energy-saving. It employs simple and convenient means of installation and maintenance to reduce customers’ OAM costs and help enterprise customers build a next-generation IT network.

Comprehensive QoS policies and security mechanisms

The CS3-248FC4TF supports strict ARP learning, which prevents ARP spoofing attacks that exhaust ARP entries, CS3-248FC4TF also provides IP source guard to prevent DoS attacks caused by MAC address spoofing, IP address spoofing, and MAC/IP spoofing.

The CS3-248FC4TF supports DHCP snooping, which generates user binding entries based on users’ access interfaces, MAC addresses, IP addresses, IP address leases, and VLAN IDs. DHCP snooping discards invalid packets that do not match any binding entries, such as ARP spoofing packets and IP spoofing packets. This prevents hackers from using ARP packets to initiate man-in-the-middle attacks on campus networks. The interface connected to a DHCP server can be configured as a trusted interface to protect the system against bogus DHCP server attacks.


Easy deployment and maintenance free

Supports SNMP v1/v2/v3 and provides flexible methods for managing devices. Users can manage the CS3-248FC4TF using the CLI and Web NMS. Supports SSH2.0 and other encryption, which makes management much more secure. Supports LLDP protocol for simpler management.
