Cisco Catalyst 2950 Overview:

The Cisco Catalyst 2950 switches are one of the longest running and most deployed Fast Ethernet and Gigabit Ethernet connectivity switches offered. This particular switch family made its mark with two distinct groups of software features and a whole host of configurations that make it ideal for any size of business from enterprise branches, to midsize and small size sectors. Plus, with the perfect combination of price to performance, it provided a network edge over competing models. Even today, after Cisco has pulled support for some of the 2950 switches and branded them as legacy devices, we still sell literal tons of them monthly and continue to provide OEM support to vast numbers of them.

What Makes the Cisco 2950 Stand Apart?

All Cisco 2950s come with a standard image software that provides basic functions such as voice, video and data services and networks that demand higher level of security. It offers additional security, high availability and an advanced quality of service (Q0S). This Enhanced Image Software helps deliver intelligent services like security filtering and rate limiting. As for industrial level networks, the Catalyst 2950 offered a new switch solution perfect for intelligent transportation systems or ITSs, industrial Ethernet deployment and transportation network solutions. In fact, the military continues to use these switches in many parts of the world where commercial switching products can't really live up to environmental conditions of the area. All Catalyst 2950 switch series rely on the Cisco Network Assistant, a free centralized management app that helps simplify the administration of Cisco routers, wireless access points and switches. This GUI interface is intuitive, ergonomically designed and easy to troubleshoot and configure. The CNA helps monitor and enable a kitchen sink of tools and features on any network.

Overall Review

Cisco Systems targets the basic entry level customers within the enterprise market with their Catalyst 2950 line. All switches are rated at an impressive 8.8 Gbps throughput and a maximum forwarding bandwidth of around 4.4 Gbps. These benchmarks alone speak volumes about the quality of the product. Considering how long the Cisco 2950 switches have managed to stay relevant and popular on the market, one can only summarize by saying that this is a line of strong performing, high quality, full featured switches at an extremely affordable and attractive price. Consider the features the 2950 line comes with. To start with a highly ergonomic administer friendly management panel. Then there is QoS add traffic management components, IGMP snooping and VLANs. Rounding all this of is the incorporation of 802.1p, 802.1q, round-robin procedures and strict priority for the QoS. CLI, Telnet or CMS (Cisco's own Cluster Management Suite) delivers flawless switch management. In particular the CMS uses Java 2 runtime and applets, with the greatest benefit being the ability to actually manage a large cluster of Cisco devices in a single interface. However, the interface itself might need a bit of polishing. Let's now review some common Cisco 2950 switches.
