Cisco Switching/Routing :: Old WS-C3750G-48TS Works With New Replacement (WS-C3750X-48T-E)

Aug 12, 2012

Situation: Currently WS-C3750G-48TS-(S or E) switches are on stack. Now these units will soon EOL on Jan. 30, 2013 and Cisco recommends that
WS-C3750X-48T-S or WS-C3750X-48T-E will be used.
  
The question is: Will the new SKU works together in a stack with the old ones?  Will there be no changes on the type of stacking cable to be used?

Cisco WAN :: WS-C3750G-48TS-S Quiet Replacement Fan?

May 3, 2013

Any replacement fan for the WS-C3750G-48TS-S switch that runs quieter than the one originally built into this router?  I've searched a number of web sites and found plenty of replacement fans available but none of them show noise level specifications.
 
particular manufacturer/model combination that works in this router that will drop the noise level down while maintaining air flow.  This switch is in a short network rack in an small office that also includes people.  The current noise level isn't defining like some servers, but is loud enough to be distracting.

Cisco Switching/Routing :: Stack C3750G And C3750X - Major Version Mismatch

Jun 11, 2013

I'm trying to stack 3750G & 3750X. As discussed in previous threads I am aware of that the version need to match.
 
Here the switch details:
 
Switch Ports Model              SW Version                SW Image
------ ----- --------------             ----------
* 1 24    WS-C3750G-24T      12.2(55)SE7             C3750-IPBASEK9-M
---------------------------------------------------------------------------------------------------------------
* 1 54      WS-C3750X-48      12.2(55)SE7           C3750E-IPBASEK9-M
 
I have changed the universal IOS on the 3750X to IP base..but they still wont come up as a stack. On the 3750X I don't see any log entry, on 3750G (major version mismatch).

Cisco WAN :: Mixed Stack C3750G And C3750X IOS Update Required

Sep 6, 2011

I have running a Stack with two C3750G-24TS-S1U with the IOS c3750-ipbasek9-mz.122-50.SE3.Now I want put a new C3750X-24T-S in the existing stack. I have read this is possible. I have running a other mixed stack with a C3750G-12S and an C3750E-48TD. Its running fine until I want to make an IOS update. The update was done with the CW LMS 3.1. After the automatic update and restart only the C3750E had an new IOS the C3750G doesn't have any IOS. Do I have the same problem with the mixed Stack C3750G and C3750X?Do I have to upgrade the IOS by copying the different IOS Versions ( c3750-ipbasek9-mz.122-50.SE3 / c3750e-ipbasek9-mz.122-50.SE3) to every switch ?

Cisco Switching/Routing :: WS-C2960S-48TS-L / Reasons To Limit 1Gb Capable Switches To 100Mb?

Jul 8, 2012

Our network administrator restricts all our new 1Gb switches to only 100Mb, to which he claims it will increase overall performance. Preventing devices from bottlenecking the network. (that is, only restricting the main switch ports, not the uplinks)For example we have a new building with 2x WS-C2960S-48TS-L connected together with FlexJack and then a 1Gb Fiber connection back to our core switch.
 
This building is on it's own subnet and there is little broadcast traffic. I don't see the point other than it hinders the potential speed we could use. Labs are set up in this building and 1Gb is MUCH faster when it comes to imaging and software deployment.

Cisco Switching/Routing :: High CPU In WS-C3750X-48

Currently, my Cisco 3750x (2 switches stacking) is having very hight CPU. Below are some of the output :

Cisco Switching/Routing :: WS-C3750G-48PS IOS Upgrade

Sep 11, 2012

I am in the process of upgrading our stack of 4 switches consist of WS-C3750G-48PS. Upon reading release notes found that there are two versions of release notes 1 day apart, the one 02 Sep 2012 saying that WS-C3750-48PS is not supported in this version. Then in release next day 03 Sep 2012 that note has been removed. Which one is correct. Is it supported with my model of switch or not. Also unable to update boot path in the stack switches, "switch all" is not supported in the current IOS. Any other way to update it. Master switch has new boot path but unable to change in slaves.

I have downloaded c3750-ipservicesk9-mz.150-1.SE2.bin and I want to upgrade iOS to this image.
 
I have a few questions related to this:
 
1. Is my switch model compatible with this iOS version?

2. Do you recommend the upgrade? Does it bring some notable features?

3. Can I upgrade for free or do I need to buy some license?

4. I also want to upgrade/add the crypto image, can I add crypto for free or some license is required?

5. I have remote access to my switch via the console cable which plugged into machine1. But machine1 is connected to network via the same switch. I am accessing machine1 via SSH, and then the switch via console cable (minicom on CentOS). Is there an upgrade procedure for this kind of situation that also has some fall back (like reboot in X minutes and load the previous image) if the upgrade goes wrong?

Cisco Switching/Routing :: WS-C3750X-48T-S - No Shutdown / Not Working

Jan 5, 2013

I'm experiencing strange issue with my WS-C3750X-48T-S.

Model number: WS-C3750X-48T-S
System image file is "flash:/c3750e-universalk9-mz.122-55.SE3/c3750e-universalk9-mz.122-55.SE3.bin"
  
This switch is situated on a remote site and on the 6th of January it was rebooted.
I still do not know the cause, but it might be power outage or smth. We are still checking. After the reboot I've noticed that one port on this cisco switch is in 'notconnect' state, while I'm pretty sure it should be 'connected'.
 
I've tried to shutdown the port adminstratevly and do the 'no shutdown' but this port remained in 'disable' state.
