Product features

Shared-buffer architecture
All Cisco Catalyst 4900 series switches are designed using a simple yet highly scalable architecture. One of the main differences between the Cisco Catalyst 4900 series and other data center platforms is the shared-memory architecture, which reduces the need for latency and jitter causing internal packet copy operations from one buffer space to another. This shared memory space has an additional advantage in multicast environments, in which a single packet may be transmitted from any number of ports without replication of the packet payload internally. Thus, this switch series provides a write-once architecture.
Smart top-of-rack design
Historically, data center design engineers have had to trade off access-layer features such as QoS, network visibility, and security when moving from an end-of-row (EoR) to a ToR data center design. The Cisco Catalyst 4948E-F offers the same features found on large EoR data center switches in a 1RU form factor optimized for ToR deployments.
Predictable performance and scalability
The Cisco Catalyst 4948E-F, with its advanced multicast support, is optimized for multimedia applications. It supports Protocol Independent Multicast (PIM), Source-Specific Multicast (SSM), and Pragmatic General Multicast (PGM), providing end users with additional scalability to support multimedia applications. Also supported are Internet Group Management Protocol (IGMP) snooping and Multicast Listener Discovery (MLD) snooping in hardware, enhancing performance and reducing network traffic by allowing a switch to dynamically add and remove hosts from a multicast group.
Intelligent network services with QoS and sophisticated traffic management
The Cisco Catalyst 4948E-F offers superior per-port QoS features to help ensure that network traffic is classified, prioritized, and scheduled optimally to efficiently manage bandwidth-intensive multimedia and time-sensitive and mission-critical applications. The Cisco Catalyst 4948E-F can classify, monitor, and mark incoming packets, allowing the administrator to differentiate traffic flows and enforce policies. Sharing, shaping, and strict-priority configurations determine scheduling of egress traffic.
