The WS-X4306-GB is ideal for our network setup. It ensures stable, fast performance and handles high-density environments effortlessly.
The WS-X4306-GB is a half-width linecard for Cisco Catalyst 4500 series switches that provides 48 100BASE-X ports via optional SFP uplinks for flexible fiber connectivity.
The WS-X4306-GB is compatible with Cisco Catalyst 4500 and 4500E chassis equipped with any Supervisor Engine 6, 7L, or 8 for seamless integration and full feature support.
This linecard delivers 48 independent 100 Mbps ports with full-duplex support, providing up to 4.8 Gbps per direction or 9.6 Gbps aggregate switching capacity.
The WS-X4306-GB supports Cisco-approved 100BASE-X SFPs such as GLC-FE-100FX, GLC-FE-100LX, and third-party MSA-compliant modules for multimode or single-mode fiber links.
At 64-byte frames, the WS-X4306-GB can forward up to 7.2 million packets per second, ensuring low latency and consistent performance.
No additional licensing is required; the WS-X4306-GB is covered under the base Cisco IOS feature set installed on the Catalyst supervisor engine.
The WS-X4306-GB is supported on Cisco IOS Software 12.2(25)E or later and Cisco IOS XE releases that run on Supervisor Engines 7L and 8.
Power down the switch chassis, insert the linecard into an available slot until it clicks into place, secure it with captive screws, then power up and verify recognition via the supervisor console.
Use “show module” to confirm the linecard is online and “show interfaces status” to verify port status; SNMP and Cisco Prime Infrastructure also provide real-time health metrics.
The linecard supports per-port QoS policies, 802.1Q VLAN trunking, private VLANs, port-based rate limiting, and CoS marking for enterprise traffic management.
The WS-X4306-GB consumes approximately 45 Watts; ensure the chassis cooling system meets the minimum fan airflow of 350 CFM per bay to maintain optimal operating temperature.
Use built-in Cisco IOS commands such as “show controllers sfp” and “show interfaces counters errors” to isolate link issues; run hardware diagnostics via Embedded Event Manager (EEM) policies for proactive alerts.
The WS-X4306-GB boasts an MTBF of over 100,000 hours under normal operating conditions, reflecting Cisco’s design for high availability and reliability.
Cisco provides a limited lifetime warranty for the WS-X4306-GB with next-business-day replacement when covered under a valid Cisco SMARTnet or Cisco Service Agreement.
Unlike Gigabit linecards, the WS-X4306-GB is optimized for high-density 100 Mbps deployments, offering cost-effective Fast Ethernet ports while leaving uplinks flexible via SFPs.
You can upgrade to Cisco Catalyst 4500E Gigabit or 10 Gigabit Ethernet linecards such as the WS-X45-G2 or WS-X4624-SFP to increase port speeds and overall switch capacity.
