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. Master switch has new boot path but unable to change in slaves.

Currently there are three stacked WS-C3750G-24TS-1U on data centre. I am going to buy a WS-C3560X-48T-L to use 10GbE module. Is it possible stack this switch "WS-C3560X-48T-L" to current switches "WS-C3750G-24TS-1U" ?

I have two Switches which i need to put in a same stack - WS-C3750E-48TD and WS-C3750G-48TS . Possible to do so and also which IOS to put in both the switches as WS-C3750G-48TS is having lower RAM and flash.Whether can i put following IOS in these switches and connect them in a stack as i have read that IOS -- 15.0.1. SE are compatible with both the switches.
a . c3750e-ipbasek9-mz.150-1.SE.bin in switch - WS-C3750E-48TD
b. c3750-ipbasek9-mz.150-1.SE.bin in switch -- WS-C3750G-48TS

I have 8 switch stack consisting of six WS-C3550-48P and two WS-C3750G-16TD running software vesrion 12.2(25) SEB1. When I added new C3750v2-24PS (running image 12.2(50) SE5) in stack so I up-graded the image of existing 8 switches with latest veriosn 12.2(50) SE5. Once I have done with the upgrade then all ports of my stack switches went down after around five minuts. Is it image compatibility issue with existing switches or something else?

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).

WS-C3750G-24TS-S1U switch stack with high CPU utilization. 3 switches are stacked and using PBR on that. I am attaching the show cpu process as an attachment.The current template is "desktop routing" template.The selected template optimizes the resources in the switch to support this level of features for 8 routed interfaces and 1024 VLANs.

I have a customer with a 3750x4 stack. We rebooted the stack over the weekend and the master did not come back up. Upon investigation it was discovered that tghe master was set for Manual Boot. I tried issuing the "no boot manual" command in Global Config mode but it did not change the variable according to a show boot command. According to Cisco documentation, the "no boot manual" command only works on standalone devices. Any way to change the variable while the switch is a member of a stack?

I have been experiencing a strange problem i have a switch stack of 3750 in which 4 switches are cascaded. there is one one switch shows PROVISIONED status when I run "show switch". i have verified the stack cable connectivity its OK.
now when i try to console that particular switch i am unable to access it as well. I tried to reboot that switch and on reboot it only shows one LED syst blink once and after that remains constant and nothing happens to other LEDS. from the back of the switch FAN is working fine.

I can see the boot file at 192.168.100.1 but I can never get into the GUI. The unit boots up, fans running. Eventually the power light flashes red. I don't have the unit hooked up to anything else except a laptop to try and configure it.

Customer is using SUP720 with SP rommon image version 8.1(3), he is trying to boot the new ios image from disk0, but he gets invalid magic error. he fomat the disk0 but still he gets error when he boots from disk0. He suspect that it can't be flash problem but can be software of hardware as he has two flash with same issue on 2 switches.
Customer wanted to recreate, I tried in the lab, i was able to load from disk0, but sup in lab had 8.5(4).
Customer wanted me try with 8.1(3) version. But i was unable to downgrade the SP Rommon image. SP rommon is running in Gold region and I loaded the 8.1(3) from both disk0 and sup-bootdisk, even preferrence was given to region1 but still sup came up with gold region itself.
* Will i be able to downgrade from 8.5(4) to 8.1(3), if so, what are the steps.
* is there any limitation or bug where 8.1(3) will be unable to read disk0.

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 ?

Is there a stacking cable that is "bent"?Im using this cable:"CAB-STACK-50CM", "Cisco StackWise 50CM Stacking Cable".But it takes up to much room in the back of the switch, is there such a thing as "bent" stacking cable.

A site that i am responsible for has the following equipment installed:
2 x 3750G Switches configured as a stack using Stackwise - Collapsed Core/Distribution Layer
5 x 2960G Switches as Access Layer switches
WAN connections into the Core/Distribution Layer are all Gigabit Ethernet over Fibre.This is a dedicated CCTV Network with 50 Cameras all streaming video into the Core (decoders connected to access switches)Each 2960G has 2 links to the Core/Distribution 3750G Switches, 1 to each switch - Gigabit.I'm running rapid-pvst on all switches, so spanning tree is blocking one of the ports and effectively halving the 2 gig bandwidth. Next year our customer is going to add in a further 50 - 60 cameras.After monitoring the current loading on the ports in use, we have suggested to the customer that the 2 connections to each should be Ether-channeled together. [code]
First interface takes commands no problem, keep getting the message that etherchannel cannot be configured across different switches in a stack when i try to put the second interface commands on.

We recently connected a RPS 2300 to our switch WS-C3750G-48PS-E with IOS c3750-ipservicesk9-mz.122-53.SE2.bin.However i do not see any RPS details in the"show env" output.I believe i should get the RPS Name and its Serial and the port number in the output, but i am not finding it in the output. I did reload the switch but still couldnot get this udpated.

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?

I currently have a C3750G connected to a C3560G with default auto-negotiation settings. Ports are up and connected a-100 and a-full. I am trying to change the ports speed to 1G, and have tried all possible combinations of "speed 1000" and "duplex full" setting on both ends to no avail. What should port settings be for 1G speed between the two switches?
Here are the current port settings:C3750G:
