I used a 3550 with the EMI image and a 2950 with the enchanced image to get me through CCNP.


Any 3550 you buy will be ok for memory.

The 3550 comes with either a SMI image or an EMI image. The SMI supports some basic routing functions ( I think it's just RIPv2 ) the EMI image supports EIGRP,OSPF, BGP,HSRP and PIM.


More details on the different images can be found here. http://www.cisco.com/en/US/products/hw/switches/ps646/products_configuration_example09186a0080169623.shtml#concept2


The 2950 has no routing capabilities but coupled with the 3550 its useful for playing with Etherchannel, STP, VTP, trunking etc.

If I want to use 2600 router for dot1q encapsulation, actually as "Router on a Stick", what would be appropriate IOS, flash and Dram requirement?

The above link shows a few router models and lists IOS versions and feature sets required for 802.1q Router on a stick configurations.


The best check is to go to the cisco feature navigator ( www.cisco.com/go/fn )


search by feature and select "IEEE 802.1Q VLAN Trunking"


filter by Platform and select your particular model.


You will then be presented with a list of all of the IOS versions that will run on your Router and perform 802.1Q VLAN Trunking. It lists image names, DRAM and Flash requirements.


for instance ios version 12.2(8)T image c2600-is-mz.122-8.T.bin which runs on a 2620-2621 requires 16MB Flash and 64Mb DRAM.

take a look at the 3560 8 port switch. I think you'll find it's pretty cost effective, and is not EOL like the 3550 so you'll have software support for a much longer time.
