Cisco Switching/Routing :: Upgrading WS-C3750G-24TS-E1U To 15.0.1-SE2?
Feb 17, 2012
I have the following switch:
#show version
Cisco IOS Software, C3750 Software (C3750-IPSERVICES-M), Version 12.2(52)SE, RELEASE SOFTWARE (fc3)
Copyright (c) 1986-2009 by Cisco Systems, Inc.
Image text-base: 0x01000000, data-base: 0x02C00000
ROM: Bootstrap program is C3750 boot loader
BOOTLDR: C3750 Boot Loader (C3750-HBOOT-M) Version 12.2(44)SE5, RELEASE SOFTWARE (fc1)
[code]...
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?

Got 2 of these switch stacked and there is some changes that we are going to undertake which will require us to utilize the whole 8 or 4 (2 from each switch) SFP ports. Just need some adivce on which particular fiber modules should I procure. Does this switch support 10GB of SFP ?

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'm troubleshooting interface drops. However the output of the following show commands don't match number of drops. Based on the output, can you find out what is causing the drops? the G1/0/28 is the uplink. Is that just the port got overrun by the traffic?
#show int g1/0/28
GigabitEthernet1/0/28 is up, line protocol is up (connected)
Hardware is Gigabit Ethernet, address is 0019.5667.191c (bia 0019.5667.191c)

We have two switches WS-C2960S-24TS-L running in stack with running IOS c2960s-universalk9-mz.122-55.SE3.We have connected two checkpoint devices on Gi1/0/24 and Gi2/0/24 with a simple configuration:
interface range GigabitEthernet1/0/24, gi2/0/24
switchport access vlan x
switchport mode access
spanning-tree portfast
On the devices log we get the following message:
%SW_MATM-4-MACFLAP_NOTIF: Host 0000.0000.fe21 in vlan x is flapping between port Gi2/0/24 and port Gi1/0/24
The mac-address 0000.0000.fe21 is not found on any checkpoint interface. "Show mac-address int gi1/0/24 or gi2/0/24" does not show the correct mac-address of the checkpoint interface connected to the port, but instead shows 0000.0000.fe21.Is there a bug in the IOS, something wrong with the switch config or does it have something to do with the checkpoint config?

I have a got a requirement where a 24 Port Switch should have 4 SFP's and all 4 should be used at a time, So I've chosen " WS-C2960S-24TS-L"
The transeiver should be GLC-LH-SM, so kindly let me no whether I would be able to use all 4 ports at a time or not.

I just received three WS-C2960S-24TS-Land three WS-C3560E-48TD-S switches that i entered the Express Setup on as usual. On two of each type of switch i found the default network that is used to facilitate the Express Setup was 10.0.1.1 and the others used an IP range of 10.0.2.1, i realized this is a small negligible at best difference though i need to provide management with an answer as to why there is a difference between the two and can’t find anything online as to why there is a difference or something that proves there should be a difference. All the documentation I find sounding Express Setup notes that the IP range will be 10.0.1.1 not 10.0.2.1

Is there a way I can downgrade the firmware on a C3750 v2 switch 24TS-S v07 to 12.2(35) SE5. I have added this new switch to an existing stack but the FW is not compatable. I believe the answer is to upgrade the rest but I cannot afford any down time as they are used to run a CCTV securiy network 24/7. I have included details below to assist with my problem. Switch 4 is the one with a version miss match.

I would like to know if Catalyst WS-C3750G-48TS-E recognizes and understand Cisco VSS ( Virtual Switching System) . Is there a List available which tells us which Old Catalyst Switches or current switches understand Cisco VSS?

I am confused about some things regarding the different IOS versions and their compatibility with certain switch hardware. I understand the differences between the IPBASE and IPSERVICES ios but am not quite clear as to how you can tell which ios images will work on which Cisco switch model platforms, other than the fact that some switches are designed only to run the IPBASE images and others have advanced hardware to run the advanced images. For instance, if I have a 3750-24TS-E with an IPBASE ios on it, can I load an IPSERVICES ios that came from say a 3750G-24TS-E1U? whether the ios on one platform can be transferred to another?

Devices are 3750-24TS Switches, software version is 12.2(55)SE6. how to troubleshoot this issue, I have a pair of ports which are not bundling, no matter what. Is the same behavior with LACP or PAgP. In this outputs I have only the PAgP case.
Output is similar to:
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
12 Po12(SD) PAgP Fa1/0/23(I) Fa1/0/24(I)
Configuration on ports is simple:
SW1:
interface FastEthernet1/0/24
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 12 mode desirable

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.

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 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:

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
