Cisco Switch CBS350-24T-4G

The Cisco Business 350 Series Switches, part of the Cisco Business line of network solutions, is a portfolio of affordable managed switches that provides a critical building block for any small office network. Intuitive dashboard simplifies network setup, and advanced features accelerate digital transformation, while pervasive security protects business critical transactions. The Cisco Business 350 Series Switches provide the ideal combination of affordability and capabilities for small office and helps you create a more efficient, better-connected workforce.


High Reliability and Resiliency:

In a growing business where availability 24 hours a day, 7 days a week is critical, you need to ensure business continuity and that employees can always access the data and resources they need. The Cisco Business 350 Series Switches support dual images, allowing you to perform software upgrades without having to take the network offline or worry about the network going down during the upgrade.


IPv6 Support:

As the IP address scheme evolves to accommodate a growing number of network devices, the Cisco Business 350 Series Switches can support the transition to the next generation of networking. These switches continue to support previous-generation IPv4, allowing you to evolve to the new IPv6 standard at your own pace and helping ensure that your current network will continue to support your business applications in the future.


Advanced Layer 3 Traffic Management:

The Cisco Business 350 Series Switches enable a more advanced set of traffic management capabilities to help growing businesses organize their networks more effectively and efficiently. For example, the switches provide dynamic Layer 3 routing, allowing you to segment your network into workgroups and communicate across VLANs without degrading application performance.


Compact Design:

The sleek and compact design for the Cisco Business 350 Series Switches provide additional deployment flexibility, including outside wiring closet installation such as retail stores, open plan offices, and classrooms without disturbing the environment.

Up to 990 static routes and up to 128 IP interfaces


IPv6 routing:

Wirespeed routing of IPv6 packets


Layer 3 Interface: Configuration of Layer 3 interface on physical port, Link Aggregation (LAG), VLAN interface, or loopback interface


Classless Interdomain Routing (CIDR): Support for classless interdomain routing


RIP v2: Support for Routing Information Protocol version 2 for dynamic routing


Policy-Based Routing (PBR): Flexible routing control to direct packets to different next hop based on IPv4 or IPv6 Access Control List (ACL)


DHCP Server: Switch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopesSupport for DHCP options


DHCP relay at Layer 3: Relay of DHCP traffic across IP domains


User Datagram Protocol (UDP) relay:

Relay of broadcast information across Layer 3 domains for application discovery or relaying of Bootstrap Protocol (BOOTP)/DHCP packets


Priority levels: 8 hardware queues


Scheduling: Strict priority and Weighted Round-Robin (WRR)


Rate limiting: Ingress policer; egress shaping and rate control; per VLAN, per port, and flow based; 2R3C policing


Congestion avoidance: A TCP congestion avoidance algorithm is required to minimize and prevent global TCP loss synchronization


iSCSI traffic optimization: A mechanism for giving priority to iSCSI traffic over other types of traffic


Energy Detect: Automatically turns power off on RJ-45 port when detecting link down. Active mode is resumed without loss of any packets when the switch detects the link up


Cable length detection: Adjusts the signal strength based on the cable length. Reduces the power consumption for shorter cables.


EEE Compliant (802.3az): Supports IEEE 802.3az on all copper Gigabit Ethernet ports


Disable port LEDs: LEDs can be manually turned off to save on energy


Time-based port operation: Link up or down based on user-defined schedule (when the port is administratively up)
