What is the difference between a Cisco 2950 SMI and EMI. I posted a message
a few days ago and someone replied that I would need a 2950 EMI to complete
my CCNP & CCIE studies. I check in Ebay and those 2950 EMI could easily cost
me USD1000. Living in a 3rd world country, this means several months of
savings to me, not to mention that I would need several 2950 to play with.
So I have a few more questions to ask.
1. For CCNP, do I need 2950 SMI or EMI?
2. For CCIE, do I need 2950 SMI or EMI?
3. I did bump into www.cisco.com on a features chart for router IOS (e.g.
what are the features of IP, IP Plus, Enterprise). I couln't find the
samething on Cisco 2950. Anyone have any idea where?
4. What is the ideal no of Cisco 2950 and 3550 that I need to have for CCNP?
5. What is the ideal no of Cisco 2950 and 3550 that I need to have for CCIE?

.. What is Cisco EI Software?
A. The Cisco Catalyst 2950T-24, 2950C-24, and 2950G switches are installed
with Cisco EI Software, which delivers intelligent services, such as
advanced QoS, rate limiting, security filters, and multicast management, to
the network edge.
Q. What is the difference between the Cisco Catalyst 2950 SI and EI
A. The Cisco Catalyst 2950 Series includes two software image versions that
support different degrees of functionality-the Standard Image (SI) and the
Enhanced Image (EI). 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 Software functions, Fast Ethernet
connectivity, and cluster management.
The EI version is embedded in Cisco Catalyst 2950T-24, 2950C-24, 2950G-12,
2950G-24, and 2950G-48 switches, and supports advanced intelligent services,
gigabit connectivity, 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 QoS.
