– 1+1 power supply and fan redundancy for hardware replacement with no downtime
– Strict front-to-back cooling with no side or top venting
– Large shared packet buffers for microburst protection
– Nonblocking internal packet switching for east-to-west traffic patterns
– Full set of Layer 2 and 3 forwarding features
– Outstanding multicast performance
– Zero-touch provisioning with Cisco IOS? Embedded Event Manager (EEM)
– Advanced quality of service (QoS)
– IP Version 6 (IPv6) switching and routing in hardware
– Extended MAC address tables to enable server virtualization
Table 1 summarizes the main features of the Cisco Catalyst 4900 Series Switches.
The Cisco Catalyst 4948E supports three levels of Cisco IOS Software, summarized in Table 2. The basic level is LAN Base, developed for deployments that require data center – class hardware along with Layer 2 switching. The next level of software is IP Base; most customers will deploy this level of software because it offers many of the value-added Cisco features that provide operational consistency and an easy-to-manage environment. The top level of software is Enterprise Services. Enterprise Services adds support for advanced routing protocols such as Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), Intermediate System to Intermediate System (IS-IS), and Enhanced Interior Gateway Routing Protocol (EIGRP).
