Frequently Asked Questions
What are the primary port configurations available on the Cisco WS-C4948E-E? +
The WS-C4948E-E is designed for high-density environments, featuring 48 fixed 10/100/1000 Mbps RJ-45 ports for standard copper connectivity. Additionally, it includes four Small Form-Factor Pluggable (SFP) slots, providing the flexibility required for fiber-optic uplinks in core or distribution layer deployments where high-speed aggregation is essential for network performance.
Does the WS-C4948E-E support Layer 3 routing protocols for enterprise traffic? +
Yes, this model is a fully managed Layer 3 switch. It supports advanced routing protocols, including static routing, RIP, and OSPF, allowing it to efficiently handle complex inter-VLAN routing and traffic segmentation. This makes it an ideal choice for data centers or backbone campus networks requiring robust control over traffic flow and internal network intelligence.
How does the WS-C4948E-E perform in a data center environment? +
Engineered for data centers, this switch offers high throughput and low latency. With a non-blocking architecture, it ensures consistent wire-speed performance across all ports. Its design facilitates efficient rack-mount density, making it a reliable choice for server farms and high-performance computing clusters that require stable, high-speed switching fabric to prevent bottlenecks during intensive data transfer tasks.
Is the WS-C4948E-E capable of being managed via Cisco management software? +
The switch is compatible with standard Cisco management tools, supporting command-line interface (CLI) access via console or Telnet/SSH. It also integrates with SNMP, enabling administrators to monitor device health, bandwidth utilization, and port status through centralized network management platforms. This standardized management approach ensures seamless integration into existing Cisco-based enterprise infrastructures.
What is the typical deployment scenario for the Catalyst 4948E series? +
This switch is commonly deployed in top-of-rack configurations within data centers or as a high-performance wiring closet aggregator. Because of its manageable form factor and strong Layer 3 capabilities, it is perfectly suited for environments needing to bridge high-density copper server connections with high-speed fiber backbones while maintaining granular security and traffic management control.
Are there specific power redundancy features included with the WS-C4948E-E? +
The hardware is designed for high reliability, featuring support for dual, hot-swappable, redundant power supplies. This redundancy ensures continuous uptime even in the event of a power module failure. By utilizing load-sharing power supplies, network administrators can maintain critical operational availability, which is essential for mission-critical enterprise applications and data-intensive server environments.
Can I implement VLANs and security policies on this managed switch? +
The switch provides robust support for 802.1Q VLAN trunking and sophisticated security features. Administrators can configure Access Control Lists (ACLs) to filter traffic based on IP or MAC addresses, port security to prevent unauthorized access, and storm control. These features are vital for maintaining a secure, partitioned network environment that adheres to strict enterprise security standards.
Does the WS-C4948E-E support Quality of Service (QoS) configurations? +
Quality of Service is fully supported, allowing administrators to prioritize traffic based on application needs. You can classify, mark, and queue data to ensure that latency-sensitive traffic, such as VoIP or streaming services, receives preferential treatment over bulk data transfers. This level of granular traffic management is key to maintaining consistent network performance during periods of heavy congestion.
