PREDICTABLE PERFORMANCE AND SCALABILITY

The Cisco Catalyst 4948-10GE is optimized for multimedia applications with its advanced multicast support. 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 is Internet Engineering Task Force (IGMP) 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 4948-10GE offers superior per-port quality of service (QoS) features to help ensure that network traffic is classified, prioritized,

and scheduled optimally to efficiently manage bandwidth-hungry multimedia, and time-sensitive and mission-critical applications. The Catalyst

4948-10GE can classify, police, and mark incoming packets, allowing the administrator to differentiate between traffic flows and enforce policies.
