Does 3750 have any IP Base model?

[George-Sl]

Does 3750 have a None E and None X model?

Cisco Catalyst 3750G-48TS

Cisco Catalyst 3750-24PS-S

These two switches are IP Base or Lan base?

What that 5th letter means? what TS and PS-S means?

what command should I put in IOS to see if this is an IP base switch?

[Mark Malone]

Hi
These switches are now EOL , the 36 and 38s replaced them and they have now been replaced with 9200s and 9300 catalyst
Check with show license , to see what you currently have
the TS is non POE , the PS is POE
These switches used to come shipped default with lanbase layer 2 but can be upgraded to ipbase and ipservices

Hi

The G indicates the model platform (model hardware version)

TS means standard image on non poe switch
PS means standard image on poe switch

The last S indicates the image type. S for ip base version. There were E switches that were running advanced ip services image.

Show version will show you the exact image you're running.

[George-Sl]

so let me put it this way, the difference of Advanced IP services, IP Base and Lan Base on 3750 is just a matter of firmware(or IOS), or is it hardware related?

so if It's hardware related what type of 3750 should I look for that offers Advanced IP services.

Thank you so much guys for the help

Hi

Its actually just a software license that gets applied ,nothing to do with hardware,  you install the license when you add it to flash,then that basically opens up the featires available for that specific license after a quick reboot, ipbase gives you some layer 3 features  , ipservices gives you every feature available right up to BGP but there expensive licenses but cover everything available

"Does 3750 have a None E and None X model?"

Yes, the original series.

"Cisco Catalyst 3750G-48TS"

I believe the "G" is for triple speed (i.e. 10/100/1000) copper ports. Models without it are double speed (i.e. 10/100).

Some of the original 3750 series only had 16 GB flash (later models have 32 GB), avoid those with only 16 GB as it limits what IOSs can be loaded onto their flash.

The original models originally had 3 IOS versions, IPBase, IPServices and Advanced IPServices. Later IOS versions combined IPService and Advanced IPServices into one feature set version. As noted by Francesco the "S" (for standard, I recall) was if the the device came with IPBase. The "E" (for enhanced [?]) was for IPServices, if that came with the model. The Advanced IPServices I recall you had to order as a separate license upgrade.

Show version will show what IOS is running. Show flash will show what IOS version(s) are loaded onto flash.

On the original series, there's no hardware licensing restrictions. Any original 3750 will run whatever feature set is loaded onto it. However, legally for a feature set "better" than IPBase, you need to have a "paper" license for the upgrade (or had purchased the "E" variant).

BTW, one model in the original series was designed as a distribution switch. It has twice the TCAM capacity of all the other models and supports SDM templates unique to it. This model can also stack with the others, but then it cannot use its unique SDM templates.

Also BTW, there's also a very rare variant that provides a 10G port (which can only sustain 8 Gbps of throughput - probably one reason the model is so rare).

Lastly, you can mix, in the same stack, the original series with the E and X series. However, there are major improvements in the later two series that are negated by having original series units in the same stack with them.

so technically we can upload the ipservices image(ios) with the tftp to the switch without having any licenses, right?(ofc for study purposes)

one more thing, since this series is EOL, do we still need license to change the ios feature set?

[Francesco Molino]

Uploading and image like IPServices doesn't require any license to be configured but you must have purchased the license in parallel that allows you to use this image.

The platform is EOL which means it isn't sold any more and officially you don't have the right to use an ios feature if you didn't purchased it before.

[George-Sl]

about the flash size as you mentioned earlier, If I am not wrong, I guess you meant it's 16 MB not GB, right?

so what I found from the config of most of 3750E models being sold on the internet that they come with 16MB not 32MB, so I can't figure this, since 3750E has to already have Adv IP services, how can that 16MB limit be an issue?(so I guess we don't need 32MB flash for Adv IP!?) Kindly correct me if I am wrong

maybe you meant for loading Advanced Enterprise we need 32MB?

Thank you so much for putting your time

"about the flash size as you mentioned earlier, If I am not wrong, I guess you meant it's 16 MB not GB, right?"

Oops, yes correct.

"so what I found from the config of most of 3750E models being sold on the internet that they come with 16MB not 32MB, so I can't figure this, since 3750E has to already have Adv IP services, how can that 16MB limit be an issue?(so I guess we don't need 32MB flash for Adv IP!?) Kindly correct me if I am wrong"

I recall (?)most of the 12.x code will fit on a 16 MB flash, but I also recall (?) 15.x code might not. (I also recall the 3750E can run some later 12.x code versions.)

"so technically we can upload the ipservices image(ios) with the tftp to the switch without having any licenses, right?(ofc for study purposes)"

Technically yes, legally no. Legally you own the physical device but not the software on it, the latter requires a license and that, I believe, is non-transferable.

"one more thing, since this series is EOL, do we still need license to change the ios feature set?"

I believe so although I doubt Cisco would pursue you if you use an old unit non-commercially for self-study.

[George-Sl]

I found this https://www.cisco.com/c/en/us/td/docs/ios/csa/configuration/guide/csa_overview.html#wp1102603

I am a bit confused, is this for newer models or even for 3750?(or universal idk??!)

so do I need to have a License key for using the ip services features after uploading the Advanced IP Services Image?

it even says 

The Cisco IOS Software Activation feature includes Cisco IOS EXEC commands that allow these basic licensing tasks from the command line.

another question I found this 3750e switch, it says it comes with

C3750E-UNIVERSALK9-M), Version 15.2(3)E1

and

it also says

License Level: ipbase

License Type: Permanent

Next reload license Level: ipbase

As I got the concept from Cisco website, Universal Roms, they work to the extend that your license allows(has that feature), means that you don't need to upload different images, LAN Base, IP Base, IP Serv, ADV IP SERV are all on one universal image, I just need to have the key for that category, idk if I am right?

so again for study purposes and as you know these switches are expensive, is there anyway I can buy this switch that I just put on top here, and use it as ADV IP Serv?how?

[Francesco Molino]

On 3750x I'm sure and I believe it's the same for 3750e.
You'll need to install a license to get ip services features.

However you should be able to enable the feature without any licenses for a temporary period (evaluation mode). Again this is how it works in 3750x and i believe it's exactly the same on 3750e.

[Joseph W. Doherty]

I suspect the confusion is between license enforcement on an original 3750 or 3750G and and the 3750E or 3750-X. The former, I recall (I'm pretty sure) does no license enforcement. The latter two series (E and X), may (sorry I don't recall as it's been years since I had to deal with licensing on those models) have built-in license enforcement.

The original series has different IOS images per feature set. The latter had/have (?) an IPBase image and an "Universal" image, the latter's features determined by the active license (including IPBase, and if you're wondering why still have an image for IPBase image, it's physically smaller).

Francesco makes a good suggestion that you often can enable advance features for a temporary period (this mainly to get a device working while waiting for a license, equipment replacement or for evaluation purposes). The "gotcha" with the temporary license, it only allows so much time then it requires a reset code from Cisco. I.e. if it's "used up", it's no longer available.

1)So regardless of the hardware, whether it is 3750G or 3750E, can I upload or even downgrade to this image c3750-advipservicesk9-tar.122-46.SE.tar?

2)is there any difference between IOSs "Advanced IP Services Version 12.xx on 3750" and "Universal Version 12.xx with Adv IP services License on 3750E"?

3)What a L3 Switch with all Features can't do, that a router could do?

4)there is also this 3750 v2 I found C3750v2-24PS-S 24-Port that says it has this IOS c3750-ipservicesk9-mz.150 on it, do you think 3750v2 enforce the licensing check? on its advertised config it doesn't show any license, means it doesn't have license, that's why I am asking.

thx guys
