Cisco Catalyst 2950 Series

Software Feature Comparison—Standard Image (SI)

and Enhanced Image (EI) Feature Comparison

The Cisco Catalyst®2950 Series switches include two software image versions that support

different degrees of functionality—the Standard Image (SI) and the Enhanced Image (EI)

Software. The version of software depends solely on the model of switch selected, with no

upgrade capabilities.

The SI version is embedded in Cisco Catalyst 2950-12, 2950-24, and 2950SX-24 switches,

and supports basic Cisco IOS®functionality, Fast Ethernet connectivity, and cluster

management.

The EI version supports all that and more. The EI version of software is embedded in Cisco

Catalyst 2950T-24, 2950C-24, and 2950G-12, 2950G-24, 2950G-48 switches, and

supportsadvancedintelligentservices,gigabitconnectivity, and a richer set of features. These

include Cisco Spanning-Tree Protocol enhancements for high availability, access control

parameters (ACPs) for enhanced security, and Differentiated Services Code Point (DCSP)

and rate limiting for advanced quality of service.

The following tables highlight feature comparisons between the ﬁxed-conﬁguration Cisco

2900 Series XL (ﬁxed-conﬁguration Catalyst 2900 XL switches have been discontinued,

modular conﬁgurations still available).
