Cisco Catalyst 9300-48U-A - Managed switch, Grey

The Cisco Catalyst 9300-48U-A 48-port managed PoE switch (Network Advantage) is an L2/L3 unit designed for high-density enterprise network access. It features 48 Gigabit Ethernet RJ-45 ports, providing both network connectivity and Power over Ethernet (PoE) to endpoints. With a total switching capacity of 256 Gbit/s and a forwarding rate of 190.48 Mpps, the unit supports stable packet delivery to connected workstations, IP phones, and wireless access points. The combination of Layer 2 switching and Layer 3 routing allows for the segmentation and routing of data across complex corporate infrastructures.

The grey chassis is designed for rack mounting and measures 445 × 445 × 44 mm, fitting standard data centre racks. Network administrators can prioritise critical traffic, such as voice and video, using integrated Quality of Service (QoS) protocols. Access Control Lists (ACLs) secure the network by filtering data packets based on established policies. DHCP snooping prevents unauthorised IP address assignment, protecting the local area network from spoofing. Multicast support allows the hardware to distribute traffic to multiple destinations efficiently, conserving bandwidth during large-scale transmissions.

• Maintains a MAC address table of up to 32,000 entries for tracking and routing packets across extensive end-user networks.
• Supports up to 4,094 active VLANs to isolate departments or device groups at the data link layer.
• Processes jumbo frames up to 9,198 bytes, improving efficiency for large file transfers and server backups.
• Complies with IEEE networking standards, including 802.1X for port-based network access control and 802.1w for rapid spanning tree.
• Includes Management Information Base (MIB) support for integration with third-party network monitoring and diagnostic software.
