My Lab IOS

I own two 2611's one is 12.1 and another is 12.3. I also have a 3550 and 3560 and they are both 12.2. Is this going to be a problem for the CCNA?

A separate question I have is do you leave your lab running 24/7. How much does this increase your electric bill?

are the 2611's 2600xm routers or non-xm 2600 routers?
non-xm 2600 routers only support up to version 12.3 and you really should have routers that will at least support 12.4.
as far as the switches 12.2 is the last release for them. But, there are alot of releases for the version 12.2 so you might want to see how old the version you are running is. if it is a 3560-ts you could run ios version 15 on it.
and it would be nice to see what feature set of the ios you have.

Neither are XM's

Well, they are non-xm's. My first recommendation would be not to purchase them. But, you already have them. So, is it worth working on them to make them usable. the one has 64/16 for memory so you can get a version of ios 12.3 that will run ipv6. you'll have to find what that is, get it, and install it. the other only has 48/16 your going to have upgrade that to 64 mb of ram and install that same ios. These router have 10mb ethernet ports. In general, 10 mb ports don't support interVlan routing. But, I think I read somewhere that there was a particular ios that did support this. I don't know what it is, so you'll have to look it up. After doing all that work, you will still only be running 12.3 for an ios. In my opinion, you do better investing your time and money in getting some routers that will run at least ios version 12.4.

So if 12.2 is the last release for the switches am I fine there?

That depends on the number and model of devices. For example, the 2950, 2960 (26W), and 3560 (24W) switches are all under 30W, while the newer 3560E uses 141W. Based on Cisco Datasheets, it appears PoE models draw more power (16W more for the 3560-24PS vs. 3560-24TS) even without using the PoE. The 3550 uses more electricity than the 3560. Your best bet would be to look over the datasheets for each device and add up their "power @ 5% throughput" if listed (some older devices only listed the maximum power usage).

Total Watts x 24 Hours x 30 Days x Rate/kWH = Cost

Cisco 1841 = 14.4 KWH/month (No WICs per Hardware Installation Guide)
Cat. 3560-24TS = 17.3 KWH/month (5%), 19.4 KWH/month (100%)
Cat. 2960-24TT-L = 18.7 KWH/month (5%), 20.2 KWH/month (100%)
Cat. 2950-24 = 21.6 KWH/month (100%)
Cat. 3560-24PS = 28.8 KWH/month (5%), 31.0 KWH/month (100%)
Cat. 3750-24TS = 29.5 KWH/month (5%), 32.4 KWH/month (100%)
Cisco 2811 = 28.0 KWH/month ("Typical")
Cisco 2801 = 30.2 KWH/month ("Typical")
Cisco 2821 = 38.9 KWH/month ("Typical")
Cat. 3750-24FS = 42.5 KWH/month (5%), 43.9 KWH/month (100%)
Cat. 3560-48PS = 51.8 KWH/month (5%), 61.9 KWH/month (100%)
Cat. 3750G-12S = 54.0 KWH/month (5%), 72.0 KWH/month (100%)
Cat. 3550-48 = 79.2 KWH/month (100%)
Cat. 3560E-48TD = 101.5 KWH/month (5%), 108.7 KWH/month (100%)

Using the US Average of 12 cent/KWH

Cisco 1841 = $1.73/month
Cat. 3560-24TS = $2.08/month
Cat. 2960-24TT-L = $2.24/month
Cat. 2950-24 = $2.59/month
Cat. 3560-24PS = $3.46/month
Cat. 3750-24TS = $3.54/month
Cisco 2811 = $3.36/month
Cisco 2801 = $3.62/month
Cisco 2821 = $4.67/month
Cat. 3750-24FS = $5.10/month
Cat. 3560-48PS = $6.22/month
Cat. 3750G-12S = $6.48/month
Cat. 3550-48 = $9.50/month
Cat. 3560E-48TD = $12.18/month

Let's take my CCNP Lab

5 x Cisco 1841 = $8.65
1 x Cisco 2811 = $3.36
2 x Cat. 3560-24TS = $4.16
2 x Cat. 3750-24TS = $7.08

Total per Month = $23.25

Officially, 12.2 is the latest release for the 3560, but the 3560-24TS and 3560-48TS can run 15.0SE as they have 32 MB of Flash. The latest version of 12.2SE will support everything you need through CCNP.
